Description
Volumetric pipettes with 2 marks class AS 25 ml are precision glass instruments used for the accurate measurement and transfer of liquid volumes in scientific laboratories. Featuring two permanent marks that define the exact delivery volume of 25 ml, these class AS pipettes offer the tight tolerances required for quantitative analytical procedures. The specified waiting time of 5 seconds allows residual liquid to drain completely, ensuring conformity with established volumetric standards. Conformity certified and distinguished by a blue colour code, the pipettes enable rapid identification during multi-volume workflows. They are particularly suited to applications in chemical analysis, quality control and educational settings where reproducible results are critical. Offered in a convenient pack of 6 pieces and produced by manufacturer Witeg, each pipette weighs 0,035 kg net. Originating from Germany, these glass volumetric pipettes combine durability with the precision demanded by modern laboratory practice. Their design supports both routine and specialised liquid handling tasks while preserving long-term calibration stability under normal use conditions.
This article belongs on Volumetric pipettes, in Pipettes & pipette tips.

Questions about Volumetric pipettes with 2 marks class AS 25 ml
What is this article?
Volumetric pipettes with 2 marks class AS 25 ml 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.
