Questions about Graduated pipettes 20:0.1 ml, class AS,
What is this article?
Graduated pipettes 20:0.1 ml, class AS, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Graduated pipettes, inside Pipettes & pipette tips, in Lab consumables.
A graduated pipette delivers a chosen volume along a scale, to contain or to deliver as marked. Class A and class B differ in tolerance. A serological pipette is a different, usually plastic, article. Reading the meniscus and delivering correctly, blow-out or not, is printed on the pipette.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
