Description
Pellet burette 25 ml class AS with Schellbach stripe provides precise volumetric delivery for titration applications conforming to ISO 385. Graduated at 0,05 ml intervals over a 25 ml capacity, the instrument meets class AS tolerance requirements and incorporates a Schellbach stripe for improved meniscus visibility. This model includes an NS intermediate stopcock together with a lateral stopcock and NS glass plug, enabling controlled filling and dispensing from the attached 2 l reservoir bottle. The assembly is supplied calibrated and without a pressure ball. Manufactured by Witeg, the burette is intended for Schilling-type rapid-operation titration systems used in analytical chemistry and routine laboratory workflows. Glass construction with an NS glass plug supports standard laboratory handling and cleaning procedures. The pack contains 2 pc(s), offering a practical supply for laboratories that require reliable class AS performance, clear scale reading and convenient reservoir integration during serial titrations.
This article is part of Burettes, in Volumetric glassware.

Questions about Autom. burettes, Pellet, Class-AS, 25 ml
What is this article?
Autom. burettes, Pellet, Class-AS, 25 ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
