Eppendorf Research 2100 Manual Single-channel pipette, 2-20 uL, Universal tips compatible (Certified Refurbished)

The Eppendorf Research Series 2100 is a single channel, adjustable volume air-displacement pipette is designed for reliable, everyday liquid handling across a broad range of laboratory applications including pipetting and mixing liquids, filling plates and reaction vessels, and phase extraction. Operating on the air-cushion principle, it uses a precision piston-stroke mechanism with a two-stop control button - the first stop for the calibrated measuring stroke and the second for complete blow-out of residual liquid. With a variable volume of 20-200 �L, volume is set continuously via a rotating setting ring coupled to a digital display that reads from top to bottom, and the pipette can be adjusted to any value within its range rather than being limited to fixed increments.

A separate ejector button allows one-handed tip disposal without repositioning the thumb from the control button. The lower part of the pipette is autoclavable at 121 �C (1 bar, 20 minutes), and the ejection sleeve can be removed independently for sterilization, making Research 2100 pipette well suited for sterile and cell culture work.
