Description
Piston spring for 300 µl is a dedicated replacement part for 300-µL pistons used in precision laboratory pipettes. The orange colour code allows rapid visual identification during maintenance or spare-part exchange. Designed for Eppendorf Research® plus, Reference® 2 and Xplorer® (plus) models, the spring re-establishes proper piston return force and stroke behaviour essential for accurate volume dispensing. Supplied as one piece, it has a net weight of 0,002 kg, gross weight of 0,003 kg and packaging volume of 0,001 m³. The component originates from Germany (Hamburg) and is classified dual-use “Nein”, confirming its status as a standard laboratory accessory. From manufacturer Eppendorf, this Kolbenfeder meets the mechanical specifications required to keep the 300-µL piston assembly operating within original tolerances. Installation restores the spring-loaded function that supports repeatable pipetting performance in research, diagnostics and routine laboratory workflows. The part is intended solely for the listed pipette families and corresponding piston size.
This article is part of Pipette stands, calibration & accessories, in Liquid handling.

Questions about Piston spring 300µL (c)
What is this article?
Piston spring 300µL (c) 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.
