Dry Baths Accessories

<h2>What Are Dry Bath Incubator Accessories?</h2>
&nbsp;
Dry bath accessories are the secondary components that extend or optimize the functionality of a dry block heater: aluminum insert blocks that define the tube format capacity; heated lids that eliminate condensation; external temperature reference probes for calibration verification; and carrying and storage cases for portability. Because the aluminum insert block physically determines which tube formats the dry bath can process, insert block selection is the single most impactful purchase decision after the base unit itself. Most manufacturers supply one insert format as standard with the base unit; labs processing multiple tube formats must purchase additional inserts separately. Select accessories based on the tube formats used in your primary protocols, confirming that inserts are brand- and model-compatible before ordering.

<h2>How to Choose Dry Bath Accessories</h2>
&nbsp;
Aluminum insert blocks: format selection
Insert blocks are precision-machined from aluminum to accept specific tube formats with tight well tolerances (typically within plus or minus 0.1 mm of the tube's outer diameter). Common formats include: 24 wells for 0.5 mL tubes; 15-16 wells for 1.5 mL microcentrifuge tubes; 12-15 wells for 2 mL microcentrifuge tubes; 8-strip configuration for 0.2 mL PCR strip tubes; 12 wells for 15 mL conical tubes; 6 wells for 50 mL conical tubes; and a flat surface (no wells) for microplates or irregular vessels. Inserts are not universally interchangeable across brands; confirm the insert fits the specific dry bath model's block holder dimensions and, for models with auto-recognition, that the insert carries the required auto-recognition contact.
Insert material and thermal conductivity.
Aluminum (Al 6061 alloy) is the standard material for dry bath inserts due to its high thermal conductivity (approximately 167 W/m K), low density, and machinability for tight tolerances. Some specialty inserts for aggressive chemical applications use hard-anodized aluminum or stainless steel, with lower thermal conductivity but better chemical resistance. Always use manufacturer-supplied or manufacturer-approved aluminum inserts; after-market inserts with inferior tolerances reduce thermal contact and degrade temperature uniformity.
Heated lid accessories
Heated lid accessories for dry baths are sold separately for many base unit models or as an upgrade kit. When selecting a heated lid, confirm: (1) it fits the specific block footprint and height of your dry bath model; (2) the lid temperature range covers the required anti-condensation temperature (typically 60-110 degrees C); (3) the lid temperature is independently controlled from the block; and (4) the lid surface material is non-reactive with samples. For protein and enzyme protocols, a lid temperature 5-10 degrees C above the block temperature is the typical starting point.
External temperature reference probe
An external calibration probe (typically a thin RTD or thermocouple probe rated for direct insertion into a tube well, connected to a calibrated digital reference thermometer) verifies that the temperature inside the well matches the instrument's displayed setpoint. External probe verification is required for GLP-compliant and regulated laboratory protocols (ISO 9001, CLIA, cGxP) and is good practice annually for any research dry bath. Confirm that the probe diameter fits the insert well format (most probes are 2-5 mm diameter; well diameter varies by tube format) before ordering.
Carrying case for portable dry baths
Mini and portable dry bath models (Labnet PR1MA Mini, and similar) are available with dedicated carrying cases for field applications: point-of-care diagnostics, on-site environmental sampling, and field isothermal PCR or LAMP assays using a 12 V DC automotive power adapter. Carrying cases provide impact protection, secure block holder positioning, and cable management for field use.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Aluminum insert block well tolerances of plus or minus 0.1 mm ensure full circumferential contact between the tube outer wall and the block well, maximizing heat transfer and minimizing temperature gradients between the sample and the block setpoint. A loose-fitting insert with 0.5 mm or more of air gap between tube and well reduces heat transfer and can introduce a temperature lag of 1-3 degrees C compared to the block setpoint, systematically underheating samples. Heated lid accessories eliminate condensation-related volume errors of 5-15% that can occur in short (&lt;10 microliter) enzyme reactions at 37-55 degrees C over 30-60 minute incubations. Auto-recognized interchangeable block inserts (where the dry bath unit automatically detects which format insert is installed) are a standard feature on Labnet and similar mid-range dry bath models, improving setup speed and reducing configuration errors.&nbsp;

Shaking Incubator Accessories

<h2>What Are Shaking Incubator Accessories?</h2>
&nbsp;
Shaking incubator accessories are platform attachments and replacement components that secure culture vessels to the shaking deck, expand the range of vessel types a single incubator can accommodate, and maintain safe operation at high agitation speeds. The primary accessories are flask clamps (spring-type or magnetic-attachment systems) for Erlenmeyer flasks of specific volumes, tube racks for culture tubes and centrifuge tubes, microplate holders for 24-well, 96-well, and deep-well plate formats, universal platforms with non-slip surfaces for various container types, and adhesive mats for securing irregularly shaped vessels. Accessories are not universally interchangeable: platform slot patterns, clamp arm geometry, and attachment mechanisms vary by manufacturer and model, so confirm compatibility with the specific shaking incubator before ordering. Always match the flask clamp size to the exact flask volume in use; undersized clamps allow movement that damages cultures, and oversized clamps do not seat correctly in platform slots.

</ul>
&nbsp;
<h2>How to Choose Shaking Incubator Accessories</h2>
&nbsp;
Flask clamp size and type
Flask clamps are specified by flask volume: 50 mL, 125 mL, 250 mL, 500 mL, 1 L, and 2 L are the standard sizes. One-piece stainless steel clamp construction is preferable to spot-welded or riveted designs for durability at high agitation speeds. For flasks 2 L and above, clamps with a secondary girdle ring provide additional security during prolonged shaking at 200 rpm or above. Magnetic clamp systems (such as MAGic Clamp-style designs) allow tool-free, rapid exchange between flask sizes without loosening bolts.
Tube racks
Tube racks for shaking incubators accommodate standard 10 mL, 14 mL, 17 mL, 50 mL, and culture tube formats, slotted into the platform deck. Adjustable tube racks that fit multiple tube diameters offer more flexibility than fixed-diameter designs. Confirm the number of tube positions and whether the rack base fits the specific platform slot pattern of your incubator.
Microplate holders
Microplate holders secure 96-well, 24-well, deep-well (2 mL per well), and skirted PCR plate formats to the shaking platform. Platforms designed for microplates typically operate at smaller orbit sizes (19 mm) and higher speeds (up to 400 rpm) compared to flask platforms. Confirm that the holder is rated for the plate format and the speed required by your protocol.
Universal platforms and adhesive mats
Universal platforms with rubber-coated surfaces provide a non-slip base for tissue culture flasks (T-25, T-75), Petri dishes, staining trays, and containers that do not fit standard clamps. Adhesive mats function similarly and are useful for microcentrifuge tube arrays or multiple small containers. Replace adhesive mats periodically as tackiness degrades with repeated use and autoclaving.
Platform compatibility
Before purchasing accessories, identify the platform slot pattern (tab-and-slot vs. screw-mount vs. magnetic) specific to your shaking incubator model. Accessories from the same manufacturer as the incubator are the safest choice; third-party platforms may fit universal tab-and-slot patterns, but should be verified before high-speed use.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Stainless steel flask clamps are the preferred material for autoclavability and chemical resistance. Verify whether accessories can be autoclaved at 121 degrees C; not all rubber or plastic components on tube racks and mats withstand repeated steam sterilization. The load capacity of the platform (in kg per position) limits the total mass of vessel plus culture volume that can be safely agitated; exceeding this limit at high speed stresses the drive bearings. For heavy-use labs running continuous 24-hour shaking protocols, select clamps with single-piece construction and check the drive belt or brushless motor specifications for continuous-duty cycle ratings.&nbsp;

3D Rockers

<h2>What are 3D rockers?</h2>
&nbsp;
3D rockers are laboratory rocking platforms that produce motion in multiple planes simultaneously &mdash; combining the basic back-and-forth tilt of a 2D rocker with a simultaneous lateral tilt, wave motion, or orbital component &mdash; creating a complex, three-dimensional liquid flow across the platform surface. This multi-axis motion ensures that liquid reaches every part of a flat container or membrane, including corners and edges that single-axis rocking can leave as dead zones with reduced agitation. Some 3D rockers (sometimes called nutators or wave mixers) produce a gyrating or teeter-totter-plus-wave motion rather than a strict two-axis tilt.

</ul>
&nbsp;
<h2>How to choose a 3D rocker</h2>
&nbsp;
Understand the specific motion type of each 3D rocker model
The term "3D rocker" covers different motion patterns: true dual-axis tilt (simultaneous tilt on both X and Y axes), wave-motion platforms that combine tilt with a propagating wave, and nutator-style platforms that produce a gyrating circular-tilt motion. Each produces a different liquid flow pattern, and checking the manufacturer's description of the platform motion helps in predicting how liquid will move in your specific container type.
Choose a 3D rocker when corner coverage in flat containers is important
In flat containers like square or rectangular blot boxes with right-angle corners, single-axis 2D rocking may leave residual unmixed volumes in corners on each sweep. A 3D motion that alternates between both tilt axes or produces a wave ensures liquid reaches all corners on each mixing cycle, producing more uniform washing and incubation.
Use a 3D rocker with tube holders for gentle multi-directional tube incubation
Many 3D rocking platforms accept tube holder accessories that fix microcentrifuge, 15 mL, or 50 mL tubes on the platform, providing a multi-directional mixing motion for tube contents without requiring a separate dedicated tube rotator. For gentle incubations where end-over-end rotation is not required, this is a convenient multi-use configuration.
Verify speed range and tilt angle against your application requirements
3D rockers operate at lower speeds and tilt angles than orbital shakers, typically 5&ndash;25 rpm with tilt angles of 10&ndash;30&deg;. Confirm that the rocker's speed range and tilt angle are appropriate for your specific incubation &mdash; gentle cell culture rocking requires lower speed and shallower tilt than more vigorous blot washing.
Consider platform size relative to your largest container
As with 2D rockers, the platform must accommodate the largest container you intend to use, with the additional consideration that in a 3D motion platform, a container positioned asymmetrically relative to the motion center may experience less uniform agitation at its extremes.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
The nutator-style 3D rocker uses a tilting platform driven in a slow circular path rather than a strict two-axis tilt, producing a smooth gyrating motion that keeps liquids in continuous gentle motion without the periodic deceleration of back-and-forth rocking, and is a common format used for gentle hybridization and tube mixing applications in molecular biology. As of 2026, compact 3D rocking platforms with programmable speed and timer are standard in molecular biology labs handling multiple blot and hybridization incubations simultaneously.

Microcentrifuge Accessories

<h2>What Are Microcentrifuge Accessories?</h2>
&nbsp;
Microcentrifuge accessories maintain performance, extend tube-format versatility, and ensure safe operation of benchtop microcentrifuges. These include replacement fixed-angle rotors for 12&ndash;24 &times; 1.5/2.0 mL tube positions, tube adapters for 0.5 mL and 0.2 mL formats, aerosol-tight sealed rotor lids for biocontainment of infectious specimens, balance tubes for partial-load runs, and specialty rotors for PCR strips or 5.0 mL tubes where supported by the centrifuge model. All microcentrifuge accessories are model-specific, as rotor coupling systems and tube bore dimensions differ between manufacturers and even between models within the same brand, making exact model verification essential before ordering.
&nbsp;
<h2>What You Will Find:</h2>
&nbsp;
<ul>
<li>High-quality adapters and rotors for precise and reliable tube fit</li>
<li>Multiple formats including PCR strips, microtubes, plates, and spin columns</li>
<li>Specialized and high-capacity rotors for enhanced compatibility</li>
<li>Swing-out and sealed options for reliable and contamination-free processing</li>
</ul>
&nbsp;
<h2>How to Choose Microcentrifuge Accessories</h2>
&nbsp;
Replacement Rotor Identification
The rotor model number is typically printed on the rotor body or listed in the centrifuge user manual. Cross-reference it with the manufacturer's accessory catalog to confirm that the coupling system matches the centrifuge motor shaft. For standard 12-position rotors, verify compatibility with both 1.5 mL and 2.0 mL microtubes.
Tube Adapter Sizing
For 0.5 mL adapters, ensure the outer diameter closely matches the rotor bore so the tube remains secure during operation. For 0.2 mL adapters, confirm that PCR tubes are positioned correctly to achieve the intended centrifugal force while maintaining stability throughout the run.
Aerosol-Tight Sealed Lids
Choose sealed lids rated for the rotor's maximum operating RCF. O-rings should be inspected regularly for flattening, cracking, or discoloration and replaced immediately if any signs of wear appear. Maintaining replacement O-rings for frequently used lids helps ensure continued safe operation.
Specialty Rotors
Some microcentrifuge models support optional rotors for 5.0 mL tubes, PCR strips, or microplates. These accessories expand workflow flexibility but may operate at lower maximum RCF values than standard 1.5 mL rotors. Always verify the rated speed and force limits before use.
Balance Tubes
Balance tubes help maintain proper rotor balance during partial-load runs. They should closely match the mass and dimensions of the sample tubes being processed. Proper balancing reduces vibration, minimizes bearing wear, and supports long-term centrifuge performance.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Many modern fixed-angle rotors and polypropylene adapters are autoclavable, although specific sterilization requirements vary by manufacturer and material. Always follow the OEM maintenance and decontamination guidelines for each accessory. Rotor service life is generally determined by cumulative operating hours and manufacturer recommendations rather than visual appearance alone.
Sealed rotor lid systems with one-touch release mechanisms have become standard in modern molecular diagnostic laboratories, providing improved safety, easier maintenance, and enhanced biocontainment for regulated workflows.

Vortex Mixers Accessories

<h2>What are vortex mixer accessories?</h2>
&nbsp;
Vortex mixer accessories are the interchangeable cup heads, foam inserts, and platform adapters that convert a standard single-tube vortex mixer to batch-process multiple tubes or different vessel formats simultaneously. The standard single-tube cup head can be replaced with a multi-tube foam insert holding 6 to 24 microcentrifuge tubes, a tube strip or microplate adapter, or a platform-style attachment for larger vessel formats. These accessories are typically instrument-specific, using a proprietary attachment mechanism that varies between vortex mixer brands.&nbsp;

</ul>
&nbsp;
<h2>How to choose vortex mixer accessories</h2>
&nbsp;
Select foam inserts by the tube format they accommodate
Foam inserts for vortex mixers are sized to hold specific tube formats by pressing the closed tube caps into the foam at defined positions: standard microcentrifuge inserts hold 1.5 mL and 2 mL tubes, larger foam blocks accommodate 15 mL and 50 mL conical tubes, and low-profile inserts hold 0.5 mL tubes or PCR strip tubes in defined arrays. Check that the insert format matches the tube types you use most and that the insert is rated for your vortex mixer's speed range.
Confirm accessory compatibility with your vortex mixer model
Vortex mixer accessories attach via model-specific connectors &mdash; threaded onto the drive spindle or clipped onto the instrument head &mdash; and are not universally compatible between brands or models. Always check that the specific accessory is listed as compatible with your vortex mixer model before ordering.
Use a microplate adapter for 96-well plate mixing
Microplate vortex adapters replace the standard cup head with a flat or recessed platform sized to hold a standard 96-well plate, allowing entire plates to be mixed in continuous mode for ELISA plate washing steps, microplate cell resuspension, and plate-format biochemical assays. The adapter should be rated for the speed at which it will be used to prevent plate sliding.
Check that foam insert speed ratings are compatible with your operating speed
Foam inserts are rated for a maximum operating speed, and using a foam insert at speeds above its rating risks tubes not being securely retained by the foam compression at high rpm. Confirm that the insert's rated speed covers your intended operating speed before batch-processing valuable samples.
Consider a universal platform adapter for flexible use
Some vortex mixer manufacturers offer a universal platform adapter that replaces the cup head with a flat non-slip platform, accepting a wide range of vessel formats using a non-slip mat for retention. While less format-specific than a dedicated foam insert, a universal platform provides flexibility for less common vessel formats.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Foam inserts work by compressing foam around tube caps to provide frictional retention during high-speed oscillation; foam material and cell size determine tube sizes accommodated and maximum safe speed. As of 2026, inserts accommodating PCR strip tubes alongside microcentrifuge tubes in a single insert have become available, reducing the number of separate formats needed.

Microplate Reader Accessories

<h2>What Are Microplate Reader Accessories?</h2>
&nbsp;
Microplate reader accessories are supplementary components that extend detection range, maintain instrument performance, and support compliance in regulated workflows. They fall into four groups: optical accessories (filters, filter cubes, and polarizers for wavelength selection in fluorescence and absorbance detection); illumination accessories (replacement xenon flash lamps, deuterium lamps, or LED upgrade modules that provide the excitation light source); calibration and validation tools (absorbance validation plates with certified reference values, fluorescence uniformity plates, and luminescence performance standards used to verify reader performance); and automation and software accessories (reagent injectors for kinetic luminescence assays, plate stackers for unattended batch reading, and software module licenses for 21 CFR Part 11 compliance, spectral scanning, or advanced kinetics). Because accessory designs are manufacturer-specific, a filter block designed for one plate reader brand will not fit another; always order accessories using the instrument's model number as the primary specification parameter. Filter sets are the most commonly needed accessory for multi-mode readers; confirm the filter block format and thread size for your specific reader model before ordering, as filter cube dimensions vary significantly between manufacturers and generations.

&nbsp;
<h2>How to Choose Microplate Reader Accessories</h2>
&nbsp;
Filter sets for fluorescence and absorbance.
Fluorescence filter sets (excitation filter, dichroic mirror, emission filter) must match both the fluorophore's excitation and emission spectra and the filter cube housing format of the specific reader. Most microplate reader filters use standard 25 mm diameter circular filters; some readers use 12 mm micro-filters. Common fluorescence filter sets: FITC/SYBR Green (Ex 485/12 nm, Em 520/10 nm); DAPI/Hoechst (Ex 360/40 nm, Em 460/40 nm); TRITC/PI (Ex 544/10 nm, Em 620/10 nm); Cy5 (Ex 620/10 nm, Em 680/10 nm). For absorbance, filter-based readers require individual narrow-bandpass filters at the wavelengths required by each assay protocol: 450 nm for ELISA, 595 nm for Bradford, 562 nm for BCA, 260 nm, and 280 nm for nucleic acid and protein.
Replacement lamps
Xenon flash lamps are the standard excitation source in high-quality fluorescence and absorbance microplate readers; typical lamp lifetime is 500 million flashes (approximately 3 to 5 years of daily use). Lamp output decreases gradually before failure; rising CV% in repeated measurements of the same standard is the first sign of lamp degradation. Replacement xenon flash lamps are model-specific; confirm part number from the instrument manual before ordering. Some instrument manufacturers have transitioned to LED-based excitation sources, which have much longer lifetimes (50,000+ hours) and do not require routine lamp replacement.
Calibration and validation plates
Calibration plates contain certified optical standards (neutral density filters, fluorescent reference dyes at known concentrations, or luminescent reference materials) in an SBS-format plate footprint for installation in the plate carriage. They are used to verify photometric accuracy, linearity, and inter-well uniformity (CV% across all 96 or 384 wells). These verifications are required in ISO 17025 accredited labs and GLP/GMP environments, and recommended as best practice for any lab relying on quantitative plate reader data. Validation plates are model-specific and must be re-certified periodically (typically annually) by the manufacturer.
Reagent injectors
Reagent injectors are syringe-pump accessories that dispense a defined volume of reagent into each well of a microplate immediately before or during reading, required for luminescence kinetic assays (luciferase, beta-galactosidase, flash luminescence from coelenterazine), where the signal decays rapidly after reagent addition. Single injectors add one reagent (e.g., luciferase substrate); dual injectors allow sequential addition of two reagents for sequential flash and glow luminescence detection. Injectors are model-specific and must be installed and calibrated by the manufacturer or a qualified service engineer.
Plate stackers and automation accessories
Plate stacker modules load and unload microplates automatically from a tray of 10 to 50 plates, allowing unattended overnight batch reading. Integration with laboratory robotics and LIMS extends this to fully automated plate reading workflows. Plate stackers are model-specific and typically sold as separate accessories from the reader. Confirm that the plate stacker is compatible with the specific plate type (96-well standard, 384-well, with or without sealing film) and the plate loading orientation.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
Filter bandpass width (the FWHM of the filter transmission curve) affects sensitivity and selectivity. Narrower bandpass filters (10 nm FWHM) improve selectivity by excluding off-target fluorophore emission but transmit less light, reducing signal. Wider bandpass filters (20 to 40 nm) transmit more light for a brighter signal, but may allow bleed-through from closely overlapping fluorophores. In multiplex assays with two or more fluorophores, narrow bandpass emission filters reduce spectral cross-talk between channels. Optical density (OD) of the blocking region outside the transmission band should be at least OD 5 to OD 6 for fluorescence filters to prevent light leakage from the excitation source from reaching the detector.

Hotplate & Stirrer Accessories

<h2>What Are Hotplate and Stirrer Accessories?</h2>
&nbsp;
Hotplate and stirrer accessories are supplementary components for single-position and multi-position hotplate stirrers that improve temperature accuracy, expand vessel compatibility, enable reflux setups, and maintain equipment in working condition. The most important accessory for research-grade hotplate use is an external temperature probe, which monitors actual solution temperature rather than hotplate surface temperature, which can be 20 to 50 degrees C higher than the liquid in the vessel. PTFE stir bars in standard cylindrical, oval, octagonal, cross-shaped, and polygon geometries allow matching of bar shape to vessel type and mixing requirement. Support rods and clamp assemblies secure condensers, separating funnels, and other glassware above the hotplate for reflux chemistry. Magnetic stir bar retrieval wands recover stir bars from flasks without contaminating the solution. An external temperature probe is the single most impactful hotplate stirrer accessory: without one, you are controlling plate temperature, not solution temperature, and the two can differ by 20 to 50 degrees C.

<h2>How to Choose Hotplate and Stirrer Accessories</h2>
&nbsp;
External temperature probes
Confirm probe type compatibility with the hotplate stirrer model: most digital hotplate stirrers accept either a PT1000 resistance temperature detector (RTD) or a Type K thermocouple, and these are not interchangeable between models. The probe is inserted directly into the solution and feeds temperature data back to the PID controller to maintain the solution (not the plate surface) at the setpoint. Probe length and sheath material (stainless steel, glass, or PTFE) should be matched to the vessel size and chemical compatibility requirements.
PTFE stir bars: geometry and size
PTFE stir bars are available in cylindrical, oval (egg-shaped), octagonal, cross (X-shape), polygon, and ring geometries. Cylindrical bars are the most common general-purpose format. Octagonal bars provide more turbulent mixing in flat-bottomed vessels than cylindrical bars. Cross-shaped bars improve mixing in round-bottom flasks by preventing the bar from riding the wall. Ring or hoop bars are used for mixing around fixed probes or frits inside the vessel. Stir bar length is selected to match vessel diameter, typically 30 to 50% of vessel inner diameter.
Support stands and clamp sets.
Support stands (rod-and-base assemblies) mount above or adjacent to the hotplate to hold condensers, addition funnels, thermometers, and other glassware in reflux setups. Confirm rod diameter compatibility with the clamp set (most lab glassware clamps fit 12.7 mm or 16 mm rods). Weighted bases provide stability for tall assemblies. Crossbar assemblies allow horizontal positioning of clamps at adjustable heights along the support rod.
Magnetic stir bar retrieval tools
Stir bar retrievers are magnetic wands encased in a non-contaminating sleeve (PTFE or glass) that attract and remove the stir bar from a vessel without inserting fingers or metal into the sample. Available as handheld wands or bench-mounted extractors. An essential accessory for labs processing multiple samples per day, as losing track of stir bars is among the most common minor equipment management issues in bench chemistry.
Replacement sensors and calibration weights
Temperature probes degrade after repeated heating cycles or chemical exposure; replace probes showing drift against a calibrated reference thermometer. For hotplate stirrer models with external calibration weights (balance verification), confirm the weight set is OIML or ASTM traceable for regulated workflows.
&nbsp;
<h2>Specifications Context</h2>
&nbsp;
PTFE stir bars should be inspected regularly for chipped or worn PTFE coating. Bare metal exposure from a chipped bar contaminates the sample with metallic particles and alters the bar's magnetic coupling properties, resulting in reduced mixing efficiency or bar stall at lower speeds. Discard and replace any stir bar showing PTFE damage. For regulated lab environments (GMP, ISO 17025), maintain a stir bar inventory log and retire bars on a scheduled basis. External temperature probes rated for immersion in aqueous solutions should be verified against a calibrated reference thermometer at least annually; probes showing more than 1 degree C deviation should be recalibrated or replaced.&nbsp;
