Description
Blow-out volumetric pipette 25 ml class AS is a precision glass pipette for accurate liquid delivery in analytical and research laboratories. This Ausblaspipette meets class AS requirements and features a defined waiting time of 5 s together with a clear ring mark to support complete and reproducible volume transfer. DIFFICO brown marking and the blue ISO colour code enable rapid visual identification of the 25 ml nominal capacity during routine work. Offered in a practical pack of 6 pieces from manufacturer Witeg, each pipette has a net weight of 0,034 kg and is intended for volumetric analysis, solution preparation, titration and standardized sample handling. The blow-out design ensures full expulsion of the measured liquid after the waiting period, making the pipette suitable for quantitative chemistry, quality-control procedures and general laboratory applications that demand reliable class AS accuracy with glass volumetric ware.
This article is part of Volumetric pipettes, in Pipettes & pipette tips.

Questions about Blow-out volumetric pipettes 25 ml class AS
What is this article?
Blow-out volumetric pipettes 25 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.
