Description
Volumetric pipettes 12,0 ml class AS blue graduated are precision single-mark glass pipettes for accurate liquid delivery in analytical and research laboratories. These instruments belong to accuracy class AS, are calibrated to deliver (KB) and specify a waiting time of 5 seconds to reach the nominal volume. The blue graduation provides clear contrast at the meniscus, supporting reliable volume setting at 12,0 ml. Offered as a pack of 12 pieces, the pipettes suit volumetric analysis, preparation of standard solutions, titration workflows and routine wet-chemistry procedures where reproducible delivery is essential. Manufactured by Witeg, they originate from Germany and follow established class AS tolerances for laboratory glassware. The one-mark design concentrates on a single nominal capacity, reducing reading uncertainty compared with multi-graduated measuring pipettes. Blue colour coding of the graduation also aids rapid identification within mixed glassware sets. These Vollpipetten are appropriate for chemical, pharmaceutical, quality-control and teaching laboratories that require high-accuracy volumetric transfer of aqueous and many common organic liquids under controlled conditions.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes 12,0 ml class AS blue
What is this article?
Volumetric pipettes 12,0 ml class AS blue 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.
