Description
Volumetric pipettes 4,0 ml class AS are single-mark glass pipettes designed for precise volumetric delivery in analytical and routine laboratory work. These class AS instruments feature one calibration mark, a waiting time of 5 s and KB calibration, supporting accurate transfer of aqueous solutions and reagents. The brown DIFFICO finish provides a durable surface while the red colour code enables quick volume identification at the bench. Supplied in packs of 12 pieces from manufacturer Witeg, each pipette has a net weight of 0,024 kg and is intended for applications requiring high volumetric accuracy according to class AS tolerances. Typical uses include sample preparation, titrations, standard solution handling and quality-control procedures in chemical, pharmaceutical and research laboratories. The clear single-mark design minimises reading errors and supports reproducible results when proper pipetting technique and the specified waiting time are observed. These volumetric pipettes integrate readily into existing glassware workflows for reliable liquid handling.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

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