Description
Volumetric pipettes 20,0 ml class AS are high-accuracy single-mark glass pipettes manufactured in accordance with DIN EN ISO 648 for precise liquid dispensing in scientific laboratories. Belonging to accuracy class AS, they feature a standardised waiting time of 5 seconds that guarantees complete and reproducible delivery of the calibrated volume. The pipettes are finished in DIFFICO brown and carry a yellow colour code for immediate visual differentiation from other nominal sizes during multi-volume workflows. Their single-mark design concentrates exclusively on the 20,0 ml capacity, minimising parallax and reading errors in analytical chemistry, sample preparation, titration and quality-control applications. Lightweight yet durable, each pipette has a net weight of 0,032 kg. Supplied in packs of 6 pieces from manufacturer Witeg, the set provides convenient stock for routine laboratory use where class AS volumetric precision and clear colour coding are required for efficient and reliable quantitative work.

Questions about Volumetric pipettes 20,0 ml class AS
What is this article?
Volumetric pipettes 20,0 ml class AS is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Volumetric pipettes, inside Pipettes & pipette tips, in Lab consumables.
A volumetric pipette has a single mark and a bulb, and it delivers one volume with a tighter tolerance than a graduated pipette. It is for preparing standards. It is not for reagents that attack glass, and it is not a blow-out pipette unless it is marked as one.
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.
