Description
Volumetric pipettes 12,5 ml class AS are high-accuracy single-mark glass pipettes intended for precise dispensing of a fixed liquid volume in laboratory practice. Rated accuracy class AS, they are calibrated to deliver (KB) and incorporate a waiting time of 5 seconds to ensure the specified delivery volume is obtained. The DIFFICO brown marking provides durable, high-contrast indication of the nominal 12,5 ml capacity. Supplied in packs of 12 pieces and with a net weight of 0,032 kg per unit data, these pipettes support quantitative analysis, standard-solution preparation, titration and general volumetric work. Produced by manufacturer Witeg in Germany, the instruments meet conventional class AS requirements for laboratory glassware. Their one-mark construction focuses exclusively on the stated volume, minimising parallax and reading errors relative to graduated measuring pipettes. The brown DIFFICO finish assists quick visual sorting among mixed pipette sets. Suitable for analytical chemistry, quality assurance, pharmaceutical and research environments that demand reproducible class AS volumetric transfer under controlled laboratory 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 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.
