Aspirating Pipettes

What Are Aspirating Pipettes?

Aspirating pipettes are single-use polystyrene or polypropylene pipettes supplied without graduation marks or filter plugs, intended for vacuum-assisted removal of spent media, wash buffers, and supernatants from tissue culture vessels and plates. Their key distinction from serological pipettes is the absence of calibrated graduation marks — they are not used to measure volumes but to remove liquid efficiently and without contamination risk. They are used in conjunction with vacuum aspiration systems (benchtop vacuum pumps, VACUSAFE, Rainin QuickFlow, BrandTech BVC, Accuris ASPIRE) or handheld aspirators in cell culture workflows. Polystyrene construction is transparent for visual confirmation of aspiration; polypropylene Plasteur-type pipettes offer greater chemical resistance for non-standard reagents. Use aspirating pipettes for media removal; they are cheaper per unit, require no volume reading, and are optimised for rapid vacuum removal.

What you will find:

• Sterile & Individually Wrapped: Maximum protection for sensitive cultures.

• Efficiency at Scale: Available in bulk packaging for high-throughput environments.

• Versatile Design: Plugged and non-plugged options to fit your specific setup.

How to Choose Aspirating Pipettes

Diameter: 1 mL vs 2 mL vs Pasteur-equivalent
1 mL and 2 mL aspirating pipettes have narrow-bore tips suitable for aspirating from 96-well plates, 24-well plates, and culture dishes without disturbing cell monolayers. Larger-bore aspirating pipettes (equivalent to 10–25 mL serological body diameter) are used for rapid media removal from T-flasks and roller bottles. Pasteur-equivalent plastic aspirating pipettes replace glass Pasteur pipettes for routine vacuum aspiration without breakage risk.

Individual Wrapping vs Bulk Packaging
Individually wrapped aspirating pipettes maintain sterility per unit and are required for cleanroom and BSC work where contamination of unused pipettes would be unacceptable. Bulk-packed formats (100–200 per bag) reduce per-pipette cost for high-volume media removal workflows where the BSC environment maintains sterility adequately.

Plastic/Plastic Wrap vs Paper/Plastic Wrap
Plastic/plastic individually wrapped pipettes eliminate particulate generation from paper wrapping — recommended for workflows where paper fibres could contaminate sensitive cultures or downstream applications such as RNA extraction.

Compatibility with Aspiration Systems
Confirm the aspirating pipette outside diameter matches the vacuum aspiration system's cone adapter. Systems such as the Rainin QuickFlow, Integra VACUSAFE, and BrandTech BVC accept standard serological and aspirating pipette diameters; the Accuris ASPIRE uses 200–300 µL pipette tip adapters for small-volume aspiration and Pasteur pipette adapters for larger volumes.

Purity Certification
Aspirating pipettes for cell culture and RNA work should be certified sterile, DNase-free, RNase-free, non-pyrogenic, and non-cytotoxic. These pipettes provide sterility assurance level, endotoxin-free assurance, non-cytotoxicity assurance, and RNase/DNase-free assurance with every case.

Specifications Context

Aspirating pipettes are manufactured from optically clear virgin polystyrene (standard) or polypropylene (Plasteur-type) in Class 100,000 cleanroom conditions. Sterility: individually wrapped pipettes are EO-sterilised to SAL 10⁻⁶. Purity certifications per lot: sterility, non-pyrogenic, non-cytotoxic, DNase-free, RNase-free.Globe Scientific, Falcon, and Nest Scientific are the leading reference brands in this category.
