Questions about Piston spring 200µL
What is this article?
Piston spring 200µL 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.
