Choosing PFAS-free pipette tips

Fit comes first

A pipette tip that doesn't seat properly on your specific pipette model can leak, deliver inaccurate volumes, or fall off mid-transfer—no PFAS-free designation fixes a fit problem. Confirm the tip is rated for your pipette brand and model before evaluating anything else.

Volume range and graduation

Match the tip's rated volume range to your actual transfer volumes—using a tip far outside its intended range hurts accuracy at both ends of its range. Graduated tips help with visual volume checks; low-retention tips reduce sample loss to the tip's inner surface, which matters more for viscous or precious samples than for routine aqueous transfers.

Filtered vs. non-filtered

Filter tips include a barrier that blocks aerosols and liquid from reaching the pipette shaft—standard practice for PCR and other contamination-sensitive work. If your workflow doesn't need aerosol protection, non-filtered tips cost less and work fine; the filter is a specific answer to a specific contamination risk, not a universal upgrade.

What "PFAS-free" adds—and what it doesn't confirm

A PFAS-free designation addresses the tip's own material background, not its fit, accuracy, or sterility—those remain separate specifications to check independently. And as with any PFAS-free labware, the designation is typically source-designated wording from the supplier rather than an independently verified test result for that specific SKU and lot; see our PFAS evidence guide before relying on it for regulated work.
