Description
Volumetric pipettes 4,0 ml class AS USP are single-mark glass pipettes manufactured to class AS and USP requirements for high-accuracy volumetric work. Each pipette features one calibration mark, a waiting time of 5 s and a brown DIFFICO finish, with a double red colour code for clear volume recognition. All units are supplied with a batch number and an accompanying batch certificate per sales unit, supporting traceability in regulated environments. Available in packs of 12 pieces from manufacturer Witeg, the pipettes have a net weight of 0,023 kg and are suited to pharmaceutical, analytical and quality-control laboratories that require documented conformity. Typical applications include precise sample and standard preparation, titrations and controlled reagent delivery. The USP-compliant design together with the batch certificate facilitates audit-ready documentation while the class AS tolerances ensure reliable volumetric performance when the specified waiting time and correct technique are applied.

Questions about Volumetric pipettes 4,0 ml class AS USP
What is this article?
Volumetric pipettes 4,0 ml class AS USP 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.
