Description
Volumetric pipettes 12,5 ml class AS, blue are precision single-mark glass pipettes designed for accurate delivery of a fixed liquid volume in analytical laboratories. They carry accuracy class AS, are calibrated to deliver (KB) and require a waiting time of 5 seconds to achieve the nominal 12,5 ml volume. The DIFFICO blue graduation supplies clear, durable contrast at the meniscus for confident volume setting. Packaged as 12 pieces, these pipettes are well suited to volumetric analysis, preparation of standard solutions, titration sequences and routine wet-chemistry applications that depend on reproducible class AS performance. Manufactured by Witeg and originating from Germany, the instruments conform to established tolerances for high-accuracy laboratory glassware. The single-mark layout concentrates on one defined capacity, reducing reading uncertainty compared with multi-graduated measuring pipettes. Blue DIFFICO colour coding further simplifies identification within mixed glassware collections. These Vollpipetten serve chemical, pharmaceutical, quality-control and research laboratories needing reliable volumetric transfer of aqueous solutions and many common solvents under controlled conditions.

Questions about Volumetric pipettes, 12,5 ml, class AS,
What is this article?
Volumetric pipettes, 12,5 ml, class AS, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Pipettes jaugées, inside Pipettes & embouts de pipette, in Consommables.
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.
