Vacuum Filtration

<h2 dir="ltr">What are Vacuum Bottle-Top Filter Systems?</h2>
 Vacuum bottle-top filter systems are single-use, sterile filtration assemblies consisting of a graduated polystyrene funnel with an integrated membrane filter bonded to a polystyrene receiver bottle, connected by a hose-port adaptor to a house vacuum line or benchtop vacuum pump. The applied negative pressure (&minus;50 to &minus;100 kPa) draws liquid through the membrane into the receiver bottle, which is sealed after filtration for immediate use or cold-room storage.&nbsp;

<h2 dir="ltr"> How to Choose Vacuum Filtration Systems</h2>
 PES vs. PVDF Membrane for Vacuum Filtration PES membranes provide low protein binding (~1&ndash;2 &micro;g/cm&sup2;), high flow rates, and broad aqueous-solution compatibility &mdash; the standard for routine DMEM, RPMI, HBSS, PBS, and supplement-containing media sterilization. PVDF membranes have slightly lower protein binding than PES and greater chemical resistance to mild organic solvents, mild acids, and alkaline solutions. Use PVDF when filtering protein-rich solutions (FBS, antibody preparations, conditioned medium with high protein content) or when mild organic solvents are present in the filter solution. Volume Selection 250 mL systems (50 mm diameter membrane, 50 mL funnel) suit small media aliquots, supplement solutions, and transfection reagent preparations. 500 mL systems (90 mm diameter membrane, 150 mL funnel) are the routine lab workhorse for standard 500 mL media bottle preparation and FBS filtration. 1,000 mL systems (90 mm diameter membrane, 350 mL funnel) handle full-liter media preparations and large-volume buffer sterilization. All NEST systems include a pre-attached, graduated polystyrene receiver bottle in the corresponding volume. Pore Size: 0.10 &micro;m vs. 0.22 &micro;m vs. 0.45 &micro;m 0.22 &micro;m is the sterilizing grade per USP &lt;1229.2&gt; and ICH Q9: retains all bacteria and fungi; used for routine cell culture media, PBS, and buffer preparation. 0.45 &micro;m is the clarification grade: used as a pre-filtration step before 0.22 &micro;m to remove large particulates from turbid or high-biomass samples (FBS, conditioned media, cell culture supernatants, crude lysates), extending 0.22 &micro;m filter throughput by 3&ndash;5&times; on difficult samples. 0.10 &micro;m is the mycoplasma-removal grade: required when preparing media for Mycoplasma-sensitive primary cell culture or when processing serum or supplementary reagents that may harbor Mycoplasma species. Note that 0.10 &micro;m filtration is substantially slower than 0.22 &micro;m due to the tighter membrane pore structure. Practical Tips for Maximum Throughput Pre-wet the membrane by briefly passing 5&ndash;10 mL of sterile water through before the sample &mdash; this wets the hydrophilic PES or PVDF membrane and reduces initial resistance. For FBS and other viscous solutions, pre-filter through 0.45 &micro;m before the 0.22 &micro;m step. Maintain a vacuum at &minus;50 to &minus;80 kPa; excessive vacuum (&gt; &minus;100 kPa) can shear fragile membrane pores and increase non-specific protein adsorption. Do not autoclave the assembled bottle-top filter &mdash; PES and PS components are not rated for autoclave sterilization.

&nbsp;
Staining: Coplin Jars Coplin staining jars are vertical-slot containers that hold 5&ndash;10 slides facing outward, immersing them simultaneously in staining reagents &mdash; haematoxylin, eosin, Gram stains, silver stains, and alcohols. Glass Coplin jars are solvent-resistant for xylene and all laboratory alcohols; polypropylene versions are suitable for aqueous and mildly solvent-containing reagents but are not xylene-compatible. &nbsp; Transport: Slide Mailers Three mailer types address different transport needs. Flip-top plastic mailers are reusable for short-range intra-facility transport. Polypropylene mailers with red screw caps provide a leak-proof sealed closure for shipping biological specimens. Cardboard mailers offer a lower-cost option for non-biohazardous, short-distance lab-to-lab sharing. &nbsp; Bench Access: Slide Dispensers Slide dispensers hold up to 72 slides in a tilted stack, dispensing one slide at a time from the front with one-handed access. This prevents contamination from repeatedly handling the full slide stack and reduces breakage during high-volume staining sessions. &nbsp; Archiving: 20-Place File Holders and Cabinets Twenty-place slide file holders accommodate a single case's slides in a flat, portable format suitable for filing or transporting a patient case. Expandable slide storage cabinets provide modular drawer-based storage for collections that grow over time, holding 100&ndash;500+ slides per cabinet unit.

Single Channel Pipettors

<h2 dir="ltr">What Are Single-Channel Pipettors?</h2>
 A single-channel pipettor is the single most widely used liquid handling instrument in molecular biology, cell biology, and clinical research. It transfers precise volumes between 0.1 &micro;L and 5,000 &micro;L, one well or tube at a time, using an air-displacement piston mechanism. The piston creates a partial vacuum that aspirates liquid into a disposable tip; advancing the piston fully dispenses the liquid. A spring-loaded tip ejector releases the used tip without hand contact for contamination control. Manual models depend on finger force and offer simple, battery-free operation; electronic models add programmable aspiration/dispensing speeds, multi-dispense modes, and up to 5 custom pipetting programs.&nbsp; A set of four manual single-channel pipettors (P10, P20, P200, P1000) covers 95% of molecular biology liquid handling; add electronic models for high-throughput repetitive work.

 Volume Range: Build a Complete Bench Set A standard four-pipettor bench set covers P10 (1&ndash;10 &micro;L), P20 (2&ndash;20 &micro;L), P200 (20&ndash;200 &micro;L), and P1000 (100&ndash;1,000 &micro;L). For sub-microliter work (sequencing, single-cell), add a P2 (0.2&ndash;2 &micro;L). For large-volume dispensing (media prep, column loading), add a P5000 (1,000&ndash;5,000 &micro;L). Avoid selecting a volume range that places your target dispense below 20% of the maximum &mdash; accuracy degrades at the low end of any range. Manual vs Electronic Manual single-channel pipettors (Eppendorf Research Plus, Gilson PIPETMAN Classic, Rainin Pipet-Lite XLS+) are the standard for routine lab work: field-calibratable, autoclavable, and requiring no power source. Electronic single-channel pipettors (Eppendorf Research Pro, Rainin Pipet-Lite XLS+ Electronic) add: programmable aspiration/dispense speed (5 speeds), multi-dispense (repeat pipetting) mode, mix mode, dilution mode, and backlight LCD volume display. Electronic models reduce hand fatigue in workflows exceeding 200&ndash;300 tip changes per day. Tip Compatibility Three tip systems cover the market: standard conical (universal fit &mdash; fits Eppendorf Research Plus, Gilson PIPETMAN, Rainin non-LTS, Thermo, Sartorius/BioHit); Rainin LTS cylindrical (requires LTS-specific tips &mdash; lower force insertion); Eppendorf epT.I.P.S. proprietary (tightest fit for Eppendorf instruments). Select the tip system that matches your pipettor purchase and existing tip inventory before committing to a brand. Autoclavability and Chemical Resistance Manual pipettors from Eppendorf, Gilson, and Rainin have fully autoclavable lower sections (121&deg;C, 15 psi, 15 min). Electronic pipettors have autoclavable nose cones only &mdash; the electronic module cannot be autoclaved. Calibration and Service All single-channel pipettors are factory-calibrated per ISO 8655. Field recalibration tools are available for Eppendorf, Gilson, and Rainin to perform in-lab gravimetric verification without external service. 
<h2 dir="ltr"> Specifications Context </h2>
 ISO 8655 Part 2 accuracy spec for a 200 &micro;L air-displacement pipettor: &plusmn;0.8 &micro;L systematic error, &le;0.3 &micro;L random error (Eppendorf Research Plus specification at 200 &micro;L). Most manual pipettors weigh 70&ndash;120 g; electronic models weigh 150&ndash;220 g. Operating temperature range: typically 15&ndash;40&deg;C. Eppendorf Research Plus, Gilson PIPETMAN Classic, and Rainin Pipet-Lite XLS+ LTS remain the three dominant single-channel pipettor platforms in North American research labs.&nbsp;

Multi-Channel Pipettors

<h2 dir="ltr">What Are Multi-Channel Pipettors?</h2>
 A multi-channel pipettor contains 8 or 12 piston-tip cone assemblies arranged in a single row at 9 mm centre-to-centre spacing &mdash; matching the well spacing of standard 96-well plates &mdash; allowing an operator to simultaneously dispense into an entire plate row (12-channel) or column (8-channel) with a single plunger depression. This reduces the time to fill a 96-well plate from ~96 individual dispenses to 12 (8-channel) or 8 (12-channel). For 384-well plates, 16-channel models or adjustable-spacing multichannel pipettors accommodate the 4.5 mm inter-well spacing. Multi-channel pipettors are the standard instrument for ELISA plate loading, serial dilution across 96-well plates, PCR master-mix dispensing, and cell-based assay setup. An 8-channel pipettor fills a 96-well plate in 12 strokes; a 12-channel pipettor fills it in 8 &mdash; choose based on whether your workflow is row-based or column-based.

<h2 dir="ltr"> How to Choose a Multi-Channel Pipettor</h2>
 8-Channel vs 12-Channel 8-channel pipettors (8 rows) are used when working column-by-column across a 96-well plate &mdash; the standard for PCR setup, ELISA, and serial dilutions where samples run down columns. 12-channel pipettors (12 columns) are used when filling row-by-row, common for reagent dispensing from reservoirs across all 12 columns simultaneously. Both configurations dispense the same 96 wells per plate but in different orientations. Volume Range Common multi-channel volume ranges: 0.5&ndash;10 &micro;L (for low-volume PCR or sequencing), 5&ndash;50 &micro;L, 10&ndash;100 &micro;L, and 20&ndash;200 &micro;L (the most widely used range for ELISA and cell-based assays), and 30&ndash;300 &micro;L. Select the range that places your most frequent dispense volume at 50&ndash;80% of the maximum for best accuracy. Manual vs Electronic Manual multi-channel pipettors (Eppendorf Research Plus Multichannel, Gilson PIPETMAN Multichannel) require no battery and are field-calibratable. Electronic multi-channel pipettors (Eppendorf Xplorer Multichannel, Rainin Pipet-Lite L8 LTS Electronic) add programmable speed, multi-dispense mode, and reduced plunger force &mdash; particularly valuable for high-throughput plate workflows. Tip Compatibility Multi-channel pipettors use the same tip collar geometry as single-channel models: standard conical for Eppendorf Research Plus and Gilson PIPETMAN (universal-fit 8-strip tips); LTS cylindrical for Rainin L8/L12 LTS (LTS 8-strip tips). Confirm tip format matches the multichannel instrument before ordering tip strips. Adjustable Tip Spacing Eppendorf Research Plus Move It and equivalent adjustable-spacing models allow spacing between channels to be set to 4, 6, 8, or 12 mm &mdash; enabling use with 24-well, 48-well, and 384-well plate formats without a dedicated instrument for each format. 
<h2 dir="ltr"> Specifications Context</h2>
 Multi-channel pipettors are subject to ISO 8655 Part 6 (multichannel piston-operated volumetric instruments). Standard accuracy specification for a 200 &micro;L 8-channel model is &plusmn;1.5 &micro;L systematic error; inter-channel CV should be &le;1.0% to ensure well-to-well reproducibility in plate-based assays. Autoclavable lower sections are standard on Eppendorf Research Plus and Gilson PIPETMAN multichannel models. Eppendorf Research Plus Multichannel and Rainin Pipet-Lite L8/L12 LTS remain the dominant manual multichannel platforms in North American research labs.&nbsp;

Filtered Pipette Tips

<h2 dir="ltr"> What Are Filtered Pipette Tips?</h2>
 Filtered pipette tips contain a hydrophobic aerosol-barrier plug &mdash; polyethylene (PE) frit or cellulose &mdash; embedded inside the tip body, positioned to intercept aerosol and liquid that would otherwise travel up through the tip collar into the pipette barrel during dispensing or when handling volatile or splashing samples. The filter protects the pipette barrel from internal contamination (which requires costly professional decontamination) and protects samples from cross-contamination by previously deposited nucleic acids, proteins, or biohazardous material in the barrel. Filtered tips are the standard consumables for PCR and qPCR setup, RNA extraction, cDNA synthesis, working with radioactive or biohazardous agents, and any workflow where a single contaminated barrel could compromise a run or an experiment. Non-filtered tips remain appropriate for routine buffer, media, and reagent dispensing where cross-contamination through the barrel is not a concern. Use filtered tips for all nucleic acid work, PCR, and biohazardous samples; use standard tips for routine buffer and reagent dispensing.

</ul>
<h2 dir="ltr"> How to Choose Filtered Pipette Tips</h2>
 Filter Material: Polyethylene Frit vs Cellulose Hydrophobic PE frits are the most common and most studied aerosol-barrier material; they block liquid ingress reliably without absorbing sample material or releasing fibres. Cellulose filters are used in some barrier tips (including the original Thermo Barrier tips); they are effective aerosol barriers but can absorb a small volume of aqueous sample, relevant at &le;10 &micro;L, where the absorbed volume is proportionally significant.
Universal Fit vs LTS-Compatible Filtered Tips Universal filtered tips use standard collar geometry (3.8 mm for &le;10 &micro;L, 6.1 mm for &le;200 &micro;L) and fit Eppendorf, Rainin Classic (non-LTS), and Thermo pipettes. LTS-compatible filtered tips use Rainin's cylindrical LTS mounting geometry and are required for Rainin LTS pipettes.&nbsp;
Low-Retention Filtered Tips Low-retention filtered tips combine an aerosol barrier with a hydrophobic inner tip wall, reducing liquid adhesion during dispensing. They are recommended for small-volume (&le;10 &micro;L) nucleic acid work, RNA, protein, and enzyme dispensing, where both contamination protection and volume accuracy are critical.
Volume Range Filtered tips are available across 10 &micro;L (P2&ndash;P10), 20 &micro;L (P20), 100 &micro;L (P100), 200 &micro;L (P200), 300 &micro;L, 1,000 &micro;L (P1000), and 1,250 &micro;L extended formats. Extended-length filtered tips reach deep into 15 mL and 50 mL conical tubes for nucleic acid elution and sample transfer steps.
Packaging Filtered tips are typically sterile-racked (96/rack, 10 racks/box); reload/refill formats are available for high-volume filter tip users.

<h2 dir="ltr"> What Are LTS-Compatible Filter Tips?</h2>
 LTS-compatible filter tips combine two design features: the cylindrical collar geometry of Rainin's LiteTouch System (LTS), which mates with Rainin LTS pipette shafts for low-insertion-force ergonomic operation, and an integrated hydrophobic aerosol-barrier filter element that prevents aerosol droplets and liquid from reaching the pipette barrel. They are the required tip format for Rainin LTS labs running PCR, qPCR, RT-PCR, RNA extraction, nucleic acid dispensing, or any contamination-sensitive workflow where both LTS ergonomics and aerosol protection are needed simultaneously. LTS filter tips are the single correct format for Rainin LTS users doing PCR, RNA, or biohazardous work &mdash; no substitution with universal filtered tips is possible.

 Confirm LTS Instrument Only pipettes displaying 'LTS' in the model designation &mdash; Pipet-Lite XLS+ LTS, Pipet-Lite M LTS, L8 LTS, L12 LTS &mdash; accept LTS tips. Standard Rainin models (older PIPET-LITE without 'LTS') and all non-Rainin pipettes require universal-fit tips, not LTS-specific tips. Low-Retention Filter Tips for Small Volumes Low-retention LTS filter tips combine the LTS mount, aerosol barrier, and hydrophobic inner wall. Use them when dispensing &le;20 &micro;L of RNA, enzyme, or protein solutions where maximum volume recovery plus contamination protection are simultaneously required &mdash; the most stringent tip specification for Rainin LTS users. Volume Range Common LTS filter tip volumes: 20 &micro;L, 200 &micro;L, 300 &micro;L, 1,000 &micro;L, and 1,200 &micro;L. Confirm the exact volume range available in LTS-compatible filter format from your supplier, as not all volumes are available in every format from every manufacturer. OEM vs Third-Party Rainin OEM filter tips for LTS are specified to the tightest cylindrical geometry tolerance.

Pipette Tips

<h2 dir="ltr">What Are Pipette Tips?</h2>
 Pipette tips are disposable polypropylene cones that attach to the shaft of an air-displacement pipette, forming the liquid-contact surface for aspiration and dispensing. The seal between the tip collar and the pipette shaft is the single most important factor in volumetric accuracy; a poorly fitting tip introduces systematic volume error that causes the instrument to deviate from its calibrated specification. Tips span micro volumes (0.1&ndash;10 &micro;L) through standard (20&ndash;200 &micro;L and 100&ndash;1,000 &micro;L) to high-volume (up to 1,250 &micro;L), with variants for filtered aerosol protection, low-retention liquid release, extended reach into deep vessels, and wide-bore dispensing of viscous samples.&nbsp;

&nbsp;
<h2 dir="ltr">How to Choose Pipette Tips</h2>
 Collar Size and Pipette Compatibility Tip collar diameter determines fit: 3.8 mm collar for &le;10 &micro;L pipettes; 6.1 mm collar for &le;200 &micro;L; approximately 7.5&ndash;8.0 mm collar for P1000 pipettes. Universal fit tips use these standard collar sizes and are compatible with Eppendorf Research, Rainin Classic (non-LTS), Thermo Finnpipette, and Sartorius/BioHit. Rainin LTS and Eppendorf epT.I.P.S. use proprietary collar geometry and require instrument-specific tips. Filtered vs Non-Filtered Aerosol-barrier filter tips contain a hydrophobic PE or cellulose plug that blocks aerosol and liquid from reaching the pipette barrel; required for PCR, qPCR, and RT-PCR setup, RNA extraction, and work with biohazardous samples. Non-filter standard tips are appropriate for buffer, media, and reagent dispensing where cross-contamination through the barrel is not a concern. Low-Retention vs Standard Polypropylene Low-retention tips are injection-moulded from hydrophobic polypropylene with reduced surface energy or coated to minimise liquid adhesion on the inner wall. They improve accuracy at &le;10 &micro;L and for dispensing viscous, protein-containing, or organic solvent samples. Standard PP tips leave small residual volumes in the tip after dispensing; this residue is negligible at 200 &micro;L but significant at 2&ndash;5 &micro;L. Extended-Length and Wide-Bore Extended-length tips (also called long tips or gel-loading tips) reach into deep 15 mL and 50 mL tubes, cryovials, and electrophoresis gel wells. Wide-bore tips have an enlarged aperture for dispensing viscous samples, cell suspensions, and tissue lysates without shearing. Packaging Format Hinged 96-tip racks are standard for manual pipetting. Reload inserts fit into reusable rack bases to reduce per-tip cost and plastic waste. Bulk bags provide the lowest cost per tip for non-sterile applications.
&nbsp;
<h2 dir="ltr">Specifications Context</h2>
 Pipette tips are certified DNase-free, RNase-free, ATP-free, human DNA-free, PCR inhibitor-free, and pyrogen-free per independent lot testing. Virgin polypropylene free of additives, antistatic agents, and dyes is the standard material. ISO 8655 compliance for the pipette system depends on tip-pipette seal quality; confirm tip compatibility with your specific pipette model.&nbsp; Sorenson Bioscience universal and filtered tips, Globe Scientific, and Nest Scientific lines are stocked by MBP Inc.&nbsp;

<h2 dir="ltr">What Are LTS-Compatible Pipette Tips?</h2>
 LTS (LiteTouch System) pipette tips use a cylindrical collar that mates with the cylindrical shaft of Rainin LTS pipettes, as opposed to the conical taper used on standard universal-fit tips. The cylindrical-to-cylindrical interface reduces the insertion force needed to seat the tip, lowering the repetitive-strain load on the hand and wrist during high-throughput pipetting &mdash; the primary ergonomic benefit Rainin's LiteTouch design addresses.&nbsp; LTS tips are required for Rainin LTS pipettes &mdash; no other tip format seats correctly. Third-party LTS-compatible tips offer equivalent performance at a lower cost than OEM.

<h2 dir="ltr"> How to Choose LTS-Compatible Tips</h2>
 Confirm Your Pipette Has LTS Not all Rainin pipettes use LTS. Rainin Classic (original PIPET-LITE) and older Rainin models use standard conical shafts and require universal-fit tips. LTS is found on Rainin Pipet-Lite XLS+, Pipet-Lite M, and multichannel L8 and L12 LTS models. Look for 'LTS' in the model name on the pipette barrel before ordering LTS-specific tips. Filtered vs Non-Filtered Non-filtered LTS tips are appropriate for buffer, media, and reagent dispensing. Filtered LTS tips &mdash; with an aerosol-barrier element &mdash; are required for PCR, RNA, and contamination-sensitive work. See the dedicated [LTS Compatible Filter Tips](mbpinc.net/consumables/liquid-handling-products/filtered-pipette-tips/lts-compatible-filter-tips [confirmed]) page for filtered LTS options. Volume Range LTS tips span approximately 20 &micro;L through 5,000 &micro;L across single-channel and multichannel pipette ranges. Common volumes: 20 &micro;L (LTS SL L10/L20), 200 &micro;L (LTS SL L200, L300), 1,000 &micro;L (LTS SL L1000), and 5,000 &micro;L macro tips for large-volume LTS pipettors. OEM Rainin vs Third-Party Compatible Rainin OEM LTS tips are manufactured to the tightest dimensional specification for LTS instruments. Third-party LTS-compatible tips are precision-moulded to LTS cylindrical geometry and certified DNase/RNase-free; they provide equivalent performance in routine applications and are typically 20&ndash;40% lower in cost than Rainin OEM tips. For critical applications (clinical diagnostics, cGMP workflows), confirm compatibility with your quality system before switching from OEM. Packaging LTS tips are available in hinged racks (10 racks &times; 96 tips = 960 tips/box) and refill wafer inserts for compatible rack bases. Sterile and non-sterile options are available across the range. 
<h2 dir="ltr"> Specifications Context</h2>
 LTS-compatible tips are manufactured from virgin polypropylene; some formats use hydrophobic low-retention PP for reduced liquid adhesion. LTS-compatible tips use hydrophobic resin technology for low retention and are certified RNase/DNase/DNA/PCR inhibitor-free. LTS tips are available from multiple third-party suppliers at 20&ndash;40% lower cost than Rainin OEM, with equivalent documented performance.&nbsp;
