Description
Volumetric pipettes with 2 marks class AS 0,5 ml are precision glass volumetric instruments for accurate delivery of a fixed liquid volume in the laboratory. These class AS pipettes are calibrated for a nominal volume of 0,5 ml and carry two marks that define the delivery volume. Each pipette is conformity certified and specified with a waiting time of 5 s, supporting reproducible drainage after delivery. Colour coding with two black rings enables rapid visual identification of the 0,5 ml size within a mixed set of volumetric glassware. The pipettes are supplied as a pack of 12 pc(s) and have a net weight of 0,006 kg per piece; gross weight is likewise 0,006 kg. Origin is Germany, region Baden-Württemberg. These glass volumetric pipettes (Vollpipetten) from manufacturer Witeg belong to the glass pipette category and are intended for quantitative laboratory work where class AS volumetric glassware is required. The two-mark construction and defined waiting time form the basis for controlled, repeatable volume transfer in analytical and routine procedures that rely on fixed-volume glass pipettes of this type and capacity.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes with 2 marks class AS 0,5 ml
What is this article?
Volumetric pipettes with 2 marks class AS 0,5 ml 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.
