Description
Measuring pipette 20:0,1 ml class AS with zero point at the bottom is a precision glass volumetric instrument for accurate liquid handling in analytical and research laboratories. Manufactured in accordance with DIN EN ISO 385, this total-delivery (Vollablauf) pipette incorporates a defined waiting time of 5 seconds to support reproducible drainage and measurement. Durable DIFFICO brown graduations ensure long-term legibility, while the dual yellow colour-code rings allow rapid visual identification on the bench. The 20 ml nominal capacity is subdivided in 0,1 ml increments, making the pipette suitable for serial dilutions, sample preparation, titrations and routine volumetric work that demands class AS tolerance. Zero-point placement at the bottom simplifies reading and handling during repeated transfers. Supplied in practical packs of 12 pieces from manufacturer Witeg, the lightweight glass construction (net weight 0,026 kg) combines clarity with mechanical robustness for everyday use in chemistry, life-science and quality-control environments. Clear scale markings and standardised design contribute to reliable performance wherever precise liquid measurement is required.

Questions about Grad. pipette, 20:0,1 ml, class AS, 0-po
What is this article?
Grad. pipette, 20:0,1 ml, class AS, 0-po 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.
