Questions about Optifit tip 50-1200 l, Flexibulk(480)
What is this article?
Optifit tip 50-1200 l, Flexibulk(480) is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Pipette tips, inside Pipettes & pipette tips, in Lab consumables.
A pipette tip has to seal on the pipette it was designed for. Volume range, filter or no filter, sterile or not, and low-retention are the choices. A tip that merely looks the right size leaks or falls off. Racked tips and bulk tips are the same tip in different packaging.
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.
