Questions about SPARES-KIT SYSTEM SH840G
What is this article?
SPARES-KIT SYSTEM SH840G is the article on this page. Luminix Health distributes KNF for laboratory use. It sits in Pipetting accessories, inside Pipettes & pipette tips, in Lab consumables.
Pipetting accessories are the boxes, the ejectors, the spare seals and the carousel parts around a pipette and its tips. A seal set is model-specific. A tip box that does not match the rack footprint will not sit on the pipette aid.
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.
