Description
Blow-out pipettes class AS 20:0,1 ml are precision glass measuring instruments intended for accurate volumetric liquid transfer in analytical and routine laboratory work. These class AS blow-out pipettes offer a nominal capacity of 20 ml with fine 0,1 ml graduations, enabling reliable dispensing once the prescribed waiting time of 5 seconds has elapsed. Dual yellow colour-code rings allow immediate visual identification on the bench or in storage racks. The blow-out design ensures complete delivery of the measured volume by expelling the residual drop, supporting consistent results in titrations, sample preparation and quality-control procedures. Each pipette has a net weight of 0,032 kg and is supplied in practical packs of 12 pieces from manufacturer Witeg. Suitable for chemistry, life-science and industrial laboratories that require high-accuracy glassware conforming to established volumetric standards, these pipettes integrate smoothly into existing workflows while maintaining clear traceability through their distinctive colour coding and class AS performance characteristics.
This article is part of Graduated pipettes, in Pipettes & pipette tips. See also Volumetric pipettes.

Questions about Blow-out pipettes, Class AS 20:0,1ml, w
What is this article?
Blow-out pipettes, Class AS 20:0,1ml, w is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Graduated pipettes, inside Pipettes & pipette tips, in Lab consumables.
A graduated pipette delivers a chosen volume along a scale, to contain or to deliver as marked. Class A and class B differ in tolerance. A serological pipette is a different, usually plastic, article. Reading the meniscus and delivering correctly, blow-out or not, is printed on the pipette.
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.
