Are the pipettes autoclavable?

Yes, the Hamilton adjustable volume, fixed volume and multi-channel pipettes are autoclavable at 121°C without the need of disassembly or recalibration.

Why are the Hamilton pipettes autoclavable?

All materials used in the SoftGrip manual pipette, including those in the upper body, are autoclavable. Many competitor models contain materials in the upper body that cannot withstand autoclaving, causing melting or warping that leaves the pipette unusable.

When I want to autoclave the Hamilton SoftGrip ergonomic pipette, do I need to do anything special to the pipette prior?

It is suggested to loosen the lower body of the Hamilton pipette and placing it inside an autoclave bag before autoclaving. Doing so may extend the life of the pipette.

Pipette Ergonomics and Performance

We've learned that our best ideas come from listening to people in the lab who use our laboratory products. Responding to user demand, we have developed our ergonomic pipettes and pipettors with a priority on addressing the issues of hand strain, fatigue, and other repetitive strain injuries caused by daily use. You'll feel the difference the first time that you pick one up. Hamilton’s line of SoftGrip™ Pipettes are easy to use, reliable, and maximize the efficiency of your lab. Each product features a user-centric design that maximizes quality, comfort, and precision which significantly reduces your chance of injuries during liquid handling.

Single-Channel Adjustable Volume Pipettes

Available in 0.2µL - 1 mL, SoftGrip’s isolated volume adjustment increases accuracy by removing parallax errors and preventing accidental volume adjustment, thanks to our next-generation dual indicator. Hamilton pipettors boast a slim design that allows for reaching the bottom of narrow tubes without the need for extended-length tips.

Single-Channel Fixed Volume Pipettes

SoftGrip fixed volume pipettes come with a slim ejection sleeve made of chemically resistant, high-strength polymer, as well as a universal calibration key to reduce calibration time. Hamilton fixed volume pipettes are available in 5 µL - 1 mL.

Multi-Channel Pipettes

Hamilton multi-channel pipettes come with either 8 or 12 channels and are available for both 5 µL - 50 µL or 30 µL - 300 µL volumes. The movable lower body and unique long-tip ejector allow for full 360° rotation to provide maximum comfort for both right-handed and left-handed users.
