Description
Lower part with PTFE piston, variable, 2,5 mL is a specialised replacement lower part for Eppendorf Reference® 2 single-channel pipettes with a nominal volume of 2,5 mL. The unit carries a PTFE coating that provides higher chemical resistance and is designed for handling highly aggressive chemicals such as trifluoroacetic acid (TFA). Red colour coding distinguishes the 2,5 mL volume range during installation, inventory checks and daily laboratory use. After replacement of the lower part, pipette calibration is recommended so that dispensing accuracy remains within specification. Attention: the lower part is not autoclavable and should be processed only with suitable non-autoclave cleaning procedures. Delivered as one piece with a net weight of 0,045 kg and gross weight of 0,060 kg, the accessory is compact enough for organised spare-parts storage. From manufacturer Eppendorf and originating in Germany, this PTFE-coated lower part extends the chemical-compatibility options of the Reference® 2 single-channel system for research, analytical and quality-control workflows that involve demanding reagents.

Questions about Lower part with PTFE piston var. 2,5 mL
What is this article?
Lower part with PTFE piston var. 2,5 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.
