Questions about Shaft w. ejector spring Transferp. S+pro, fix 20 + 25 µl, adjustable 2 - 20 µl
What is this article?
Shaft w. ejector spring Transferp. S+pro, fix 20 + 25 µl, adjustable 2 - 20 µl is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Pipette stands, calibration & accessories, inside Liquid handling, in Instruments de laboratoire.
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.
