Description
Lower part with PTFE piston, fixed, 2 mL, red is a specialised replacement assembly for the Eppendorf Reference® 2 fixed single-channel pipette. Featuring a PTFE-coated piston, this lower part delivers elevated chemical resistance against highly aggressive reagents such as trifluoroacetic acid (TFA). The red colour code identifies the 2 mL volume according to the Reference 2 system, ensuring correct matching during service. After installation of the new lower part, pipette recalibration is recommended to restore volumetric accuracy. Important: the component is not autoclavable. Supplied as a single unit, it is intended for laboratories that routinely handle corrosive solvents and require a more durable piston interface than standard materials provide. Net weight is 0,045 kg. This PTFE-coated lower part from manufacturer Eppendorf extends the usable life of Reference 2 pipettes in demanding chemical and analytical workflows where standard lower parts would degrade more rapidly.
This article is part of Pipette stands, calibration & accessories, in Liquid handling.

Questions about Lower part with PTFE piston fix. 2 mL
What is this article?
Lower part with PTFE piston fix. 2 mL 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.
