Weighing Dishes & Boats

<h2 data-section-id="4vlupf" data-start="410" data-end="461">What Are Laboratory Weighing Dishes and Funnels?</h2>
&nbsp;
Laboratory weighing dishes and funnels are disposable antistatic consumables used in gravimetric sample preparation&mdash;where solid or liquid materials are weighed on analytical or top-loading balances before being transferred into reaction vessels, volumetric flasks, or tubes. Weighing dishes (also called weigh boats or pour boats) are flat-bottomed antistatic polystyrene containers used to hold samples on the balance pan during weighing. Weighing funnels are antistatic polypropylene tools with one flat side for stability on the balance and a conical stem designed to fit flask necks, allowing complete quantitative transfer of material with minimal loss. Globe Scientific offers antistatic PS weighing dishes in square, hexagonal, and pour-boat formats ranging from 10 mL to 350 mL, and antistatic PP weighing funnels in extra-small through extra-extra-large sizes. Both are single-use only because washing removes antistatic properties and affects weighing accuracy.

&nbsp;
Weighing Dish Shape
Square weigh boats are used for routine laboratory weighing and are designed with sloping sides and recessed corners to minimize sample loss during transfer. Hexagonal weigh boats provide better stability on balance pans due to their molded edges and also offer improved grip during handling, making them suitable for workflows where stability matters. Pour-boat designs include a built-in spout that allows controlled and accurate dispensing of liquids or viscous samples into receiving vessels without spillage.
Weighing Dish Capacity
Small 10&ndash;20 mL dishes are used for micro-scale weighing of reagents typically under 2 g on analytical balances. Medium 50&ndash;100 mL dishes are used for routine laboratory weighing of 2&ndash;20 g samples. Large 200&ndash;350 mL dishes are used for bulk powders and higher-volume transfers on top-loading balances.
Weighing Funnel Size
Extra-small funnels are used for 5&ndash;20 mL vessels and microtubes, small funnels for 20&ndash;50 mL, medium funnels for 50&ndash;200 mL, large funnels for 200&ndash;500 mL, and extra-large funnels for 500&ndash;1000 mL flasks. The flat side ensures stable placement on the balance pan during weighing before transfer.
Color: White vs. Black
White dishes provide high contrast for dark or strongly colored samples, making them easier to visualize during transfer. Black dishes are used for light-colored or transparent samples where residue visibility is important, especially when confirming complete sample recovery.

2D Rockers Accessories

<h2>What are 2D rocker accessories?</h2>
&nbsp;
2D rocker accessories are the non-slip mats, container clamps, tray organizers, and platform protection sheets that complement a 2D rocking platform for daily use with flat gel boxes, blot containers, and staining dishes. Unlike orbital shaker or tube rotator accessories that must be engineered for centrifugal force retention, 2D rocker accessories primarily address the simpler problem of keeping containers from sliding off a gently tilting platform surface. Non-slip rubber or silicone mats hold containers by friction; container clamps with spring clips grip the sides of blot boxes at higher rocking speeds; and protective mats shield the rocker platform from chemical spills from gel stains or hazardous blotting reagents.

A stacking platform with flat mat adds 3.5" clearance:&nbsp;&nbsp;for taller vessels on compatible 2D rockers, provide stable sample placement during rocking.
</li>
</ul>
&nbsp;
<h2>How to choose 2D rocker accessories</h2>
&nbsp;
Start with a non-slip mat for all routine blot and gel applications
A non-slip silicone or rubber mat placed on the 2D rocker platform surface prevents gel boxes, blot containers, and staining dishes from sliding during rocking, particularly as the tilt increases. The mat also provides a layer of chemical protection between spilled staining reagents and the rocker platform surface.
Use container clamps for larger or heavier containers at faster speeds
At rocking speeds above approximately 25&ndash;30 rpm or with larger, heavier gel staining dishes filled with destaining solution, friction alone may be insufficient to prevent sliding, and platform clamps that grip the container edges provide positive mechanical retention regardless of the speed or tilt angle.
Consider a tray divider or multiple smaller mats for running several containers
When running multiple blot containers simultaneously on a single platform, tray dividers or separate small non-slip mats for each container help organize and stabilize each container independently, preventing them from sliding into each other during rocking and ensuring each container's contents are evenly agitated.
Check platform mat dimensions match your rocker platform area
Non-slip mats are sized to fit specific platform dimensions and should not overhang the platform edges, since an overhanging mat can fold or shift during rocking and cause containers placed on it to tilt unevenly. Confirm the mat dimensions against your rocker platform dimensions before purchase.
Protect the platform surface from gel stains and corrosive reagents
Ethidium bromide, SYBR stains, Coomassie Blue, and some membrane stripping reagents can damage or stain the platform surface if spilled directly on it. A protective platform mat acts as a sacrificial barrier, absorbing spills and protecting the instrument surface, and can be cleaned or replaced when contaminated.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Non-slip platform mats for 2D rockers are typically made from silicone or natural rubber and are chemically resistant to most aqueous biological reagents, ethanol, and common blotting buffers, though concentrated organic solvents, strong acids, or bleach may degrade certain mat materials. As of 2026, silicone non-slip mats cut to standard rocker platform dimensions are the most widely used 2D rocker accessory in molecular biology labs, combining chemical resistance, non-slip surface texture, and ease of cleaning in a low-cost consumable format.

3D Rockers Accessories

<h2>What are 3D rocker accessories?</h2>
&nbsp;
3D rocker accessories are the interchangeable tube holders, platform mats, and container-retention clips that allow a 3D rocking platform to be used with different vessel types beyond flat trays resting directly on the platform surface. Tube holder accessories fix microcentrifuge, 15 mL, or 50 mL conical tubes in defined positions on the platform, enabling the 3D rocking motion to agitate tube contents without requiring a separate tube rotator. Non-slip platform mats grip trays, gel boxes, and flat containers by friction, preventing them from sliding during rocking. Container clips secure the edges of blot containers or larger trays at higher speeds.

&nbsp;
<h2>How to choose 3D rocker accessories</h2>
&nbsp;
Match tube holder accessories to your tube size and the rocker model
Tube holders for 3D rockers are designed for specific tube formats &mdash; microcentrifuge (1.5 mL and 2 mL), 15 mL conical, and 50 mL conical &mdash; and attach to the platform via a platform-specific mounting system. Confirm that the tube holder accessory is listed as compatible with your specific 3D rocker model, since mounting systems vary between manufacturers.
Use a non-slip mat for flat containers at low to moderate rocking speeds
A non-slip silicone or rubber platform mat holds flat trays and gel boxes by friction at rocking speeds up to approximately 20&ndash;25 rpm, suitable for most blot and gel incubation applications. At higher speeds or steeper tilt angles, the tray may slide despite the mat, and dedicated container clips provide more secure retention.
Choose container clips or tray holders for heavier or larger containers
For large gel staining dishes or containers with significant weight or liquid volume that might slide on the platform, dedicated container clips or tray holder frames that attach to the platform edges provide secure retention at any rocking speed. These are important when working with larger format blots or multiple staining trays simultaneously.
Consider a multi-format accessory kit for maximum versatility
A set covering a non-slip mat, microcentrifuge tube holder, and 50 mL conical tube holder allows the same 3D rocker to serve flat-surface and tube-mixing applications without separate orders per format, and is the standard starting accessory purchase for a new 3D rocker installation.
Verify material compatibility with your lab cleaning agents
Platform mats and tube holders are typically made from polypropylene, silicone, or polyurethane, and should be compatible with your lab disinfectants. Silicone mats resist common lab disinfectants; check materials for compatibility with bleach-based or solvent-based cleaning protocols used.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Tube holders for 3D rocking platforms must secure tubes against centrifugal and gravitational forces during the tilting cycle, and the holder's design determines the maximum safe rocking speed. As of 2026, universal tube holders fitting multiple formats from a single base mount have become available, reducing the number of separate accessories needed for labs mixing different tube sizes on the same 3D rocker.

Homogenizer Accessories

<h2>What are homogenizer accessories?</h2>
&nbsp;
Homogenizer accessories are the interchangeable tools, replacement parts, and supporting vessels and hardware that enable a laboratory homogenizer to be used across different sample volumes, sample types, and processing conditions beyond what the base instrument alone provides. For rotor-stator homogenizers, the critical accessories are the generator head and dispersing tool (the probe tip with rotating blade inside a stator tube), available in different sizes to match different sample volumes. For ultrasonic probe homogenizers, the primary accessories are the sonic probe tip or microtip, which is the consumable component that transmits ultrasonic energy and eventually wears or fatigues. Additional accessories include cleaning stations, jacketed vessels for temperature control, and support stands.
&nbsp;

<li>Rotor-stator homogenizer generator probes</li>
<li>Rotor-stator homogenizer probe tips and microtips</li>
<li>Bead kit and bead grinding media for bead mill homogenizers</li>
<li>Sample tube adapters and holders for homogenizers</li>

<li>Cup horns and flow cells for ultrasonic homogenizers</li>
<li>Sound chamber enclosures for noisy ultrasonic homogenizers</li>
<li>Seals and other replaceable homogenizer parts </li>
</ul>
&nbsp;
<h2>How to choose homogenizer accessories</h2>
&nbsp;
Match the generator head size to your sample volume
Rotor-stator generator heads (dispersing elements) are designed for specific volume ranges: the S10N generator head suits 0.5&ndash;30 mL, S18N suits 5&ndash;150 mL, and S25N suits 50&ndash;500 mL volumes in common IKA Ultra-Turrax style instruments. Processing a 2 mL sample with a large S25N head gives poor energy density; processing 200 mL
Check ultrasonic probe tip diameter against the sample vessel and volume
Ultrasonic probe homogenizer tips are available in standard (12.7&ndash;19 mm) and micro (3&ndash;6 mm) diameters, with the micro-tip providing higher acoustic intensity for small volumes and the standard tip covering larger volumes. The tip diameter should be approximately 1/4 to 1/3 of the diameter of the sample container for effective cavitation throughout the sample.
Replace ultrasonic probe tips before pitting becomes severe
Ultrasonic probe tips erode at the vibrating face through cavitation, and a pitted tip delivers less energy, generates metal particles contaminating the sample, and risks mechanical failure. Inspect the tip face regularly for pitting and replace at the first signs of significant erosion to maintain energy delivery.
Use a water-jacketed vessel for temperature-sensitive samples
Water-jacketed homogenization vessels circulate cold water around the sample vessel during homogenization, limiting the temperature rise in the sample from frictional and ultrasonic heating. This is particularly important for enzyme preparations, RNA isolation, and other applications where sample heating above a few degrees above ambient can cause degradation.
Invest in a probe cleaning station for high-throughput work
Probe cleaning stations hold cleaning and rinse solutions in sequence for rapid cleaning between samples, reducing cleaning time and ensuring consistent decontamination in labs processing many samples per session compared with manual cleaning.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Ultrasonic probe tip replacement is a consumable cost, with tip lifespan typically 50&ndash;200 hours before pitting degrades performance. Manufacturers specify replacement tip models compatible with each horn assembly; non-specified tips risk poor energy coupling or damage. Titanium alloy probe tips remain the standard material for their combination of acoustic properties, corrosion resistance, and fatigue resistance under repeated ultrasonic cycling.
