Description
Research 3 piston spring 2,5-20 µL grey/yellow is a specialised replacement piston spring for Eppendorf Research® 3 single-channel pipettes covering the 2,5-20 µL volume interval. The dual grey/yellow colour code corresponds to the official Eppendorf volume identification system, ensuring quick and unambiguous selection of the matching spare part. Supplied by manufacturer Eppendorf, the spring provides the calibrated return force necessary for accurate piston movement and reliable microlitre pipetting. Net weight is 0,002 kg and gross weight is 0,003 kg, resulting in a compact component that integrates directly into the original pipette mechanism. The unit is delivered as a single piece and is intended for installation by trained service personnel in accordance with manufacturer guidelines. Typical laboratory settings include molecular biology, PCR preparation, enzyme assays and other applications that demand precise low-volume liquid handling with Research® 3 instruments. Fitting this genuine spring restores the mechanical behaviour of the pipette and supports continued high-quality performance. Manufactured in Germany, the part forms an integral element of the Research® 3 spare-parts programme and helps laboratories maintain instrument integrity over long service intervals.

Questions about Res.3 piston spring 2.5-20µL gray/yellow
What is this article?
Res.3 piston spring 2.5-20µL gray/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 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.
