Description
Reference® 2 tip ejector sleeve, variable/fixed version for 20 µL, is a colour-coded replacement component finished in light grey or yellow. This dedicated Abwerfhülse restores reliable tip ejection on pipettes from the Reference® 2 series when the original sleeve becomes worn through intensive daily use. Designed specifically for the 20 µL working range, it supports both variable and fixed volume configurations while preserving the ergonomic handling characteristics of the instrument. Colour coding in light grey or yellow follows the established volume identification scheme of the pipette family, allowing quick visual verification during maintenance or reassembly. Supplied as a single piece with a net weight of 0,005 kg and a compact packaging volume of 0,001 m³, the part is convenient for laboratory service inventories and instrument workshops. Compatible with Eppendorf Reference® 2 pipettes, the sleeve helps keep precision liquid-handling tools in proper working order for research, clinical and quality-control workflows. Originating from China and classified among laboratory equipment accessories, it provides a straightforward spare-part solution without altering the calibrated performance of the pipette itself.

Questions about Ref.2 Ej.sleeve vari/fix 20uL l.gray/yel
What is this article?
Ref.2 Ej.sleeve vari/fix 20uL l.gray/yel is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Lab instruments.
A pipette stand holds piston pipettes upright so liquid does not run into the piston. Calibration accessories and certificates are how a pipette's delivered volume is shown to be inside tolerance. A stand is also a carousel. The certificate belongs to one pipette, identified by serial number.
A piston pipette delivers a set volume of liquid by air displacement or, for viscous and volatile liquids, by positive displacement. A single channel is the ordinary tool. A multichannel repeats the same volume across a row of a plate. A bottle-top dispenser meters reagent from the bottle it sits on. The accuracy is a property of the pipette and of how it is used, which is why calibration and a certificate exist. Piston-operated apparatus is treated under ISO laboratory apparatus. The volume unit sits with the BIPM and NIST.
