Eppendorf Reference 2 Manual Single-channel pipette, 0.5-10 uL, Universal tips compatible (Certified Refurbished)

The Eppendorf Reference 2 is a single channel, variable volume air-displacement pipette with a 0.5-10 �L volume built around Eppendorf's innovative single-button operating concept - a single control button handles volume setting, aspiration, dispensing, and tip ejection, eliminating the need to reposition the thumb between steps. This streamlined design not only speeds up pipetting workflows but also provides active aerosol reduction, since the tip can be ejected immediately after dispensing without reaching for a separate ejector button. A clear haptic feedback at the blow-out step helps prevent accidental tip ejection. The four-digit volume display with magnifying window is visible from every angle and is paired with a volume lock to prevent unintentional changes during pipetting cycles. For liquids with densities significantly different from water or when working at altitude, a secondary user adjustment allows the pipette to be fine-tuned without a full recalibration - and factory settings can be restored afterward.

The Reference 2 features a spring-loaded tip cone that reduces tip attachment and ejection forces, improving ergonomics and user-to-user reproducibility. Its stainless steel external edges and sturdy upper handle with spring-loaded bumpers give the pipette excellent impact resistance, helping it stay in calibration even after an accidental drop. The smooth, one-pour housing and quick-connect lower part make the Reference 2 fully autoclavable without disassembly and easy to decontaminate, making it well suited for sterile environments and cleanroom use.
