Description
Spring for piston 2,5 / 10 / 20 µL (c) is a genuine replacement piston spring intended for selected Eppendorf air-cushion pipettes. It is specified for use with Eppendorf Research® plus, Reference® 2 and Xplorer® (plus) models and fits the corresponding 2,5-µL, 10-µL and 20-µL pistons. Colour coding is grey or yellow, matching the familiar volume identification scheme of these pipette families and helping technicians select the correct spare part during maintenance. As a dedicated mechanical component, the spring restores proper piston return force and contributes to consistent pipetting feel and performance after routine service or repair. Supplied as a single piece with a net weight of only 0,002 kg, it is a compact spare part for laboratory workshops and pipette service stations. Originating from Germany, this Eppendorf accessory supports continued reliable operation of precision liquid-handling instruments in research, quality-control and routine laboratory environments where original-equipment replacement parts are preferred to maintain instrument integrity and workflow continuity.

Questions about Piston spring 2.5,10,20µL
What is this article?
Piston spring 2.5,10,20µL is the article on this page. Luminix Health distributes Eppendorf for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Instruments de précision.
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.
