Description
Research 3 single-channel piston 20 µL light grey or yellow is a precision replacement piston intended for Eppendorf Research® 3 single-channel pipettes. Colour-coded light grey or yellow, it corresponds to the 20 µL volume specification and ensures correct identification during pipette assembly or servicing. The piston is supplied as one piece and restores the mechanical integrity required for accurate aspiration and dispensing. Produced by Eppendorf, this spare part supports laboratories that depend on reliable single-channel pipetting for sample preparation, reagent addition and serial dilutions. With a net weight of 0,009 kg and gross weight of 0,010 kg it remains lightweight and convenient to handle. The dual colour option (light grey or yellow) follows the established coding scheme of the Research 3 series, helping users quickly select the correct component. Regular replacement of worn pistons maintains the pipette’s original performance characteristics and contributes to consistent results in molecular biology, analytical chemistry and routine quality-control applications.

Questions about Res.3 sing.-piston 20µL gray or yellow
What is this article?
Res.3 sing.-piston 20µL gray or yellow 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.
