Description
Burette 25 ml class AS with PTFE plug is a precision volumetric instrument for accurate titration and quantitative analysis in analytical laboratories. It offers a 25 ml capacity with 0,05 ml graduation intervals and class AS accuracy, supported by a Schellbach stripe that improves meniscus visibility and reading precision. The straight stopcock is equipped with a PTFE plug, delivering smooth control and chemical resistance without the need for grease. These burettes are conformity certified and supplied in a pack of 2 pieces, each with a net weight of 0,073 kg. Manufactured by Witeg, the clear-glass design with Schellbach stripe is well suited to acid-base, redox and complexometric titrations as well as routine volumetric work in research, quality-control and teaching laboratories. The PTFE plug maintains a reliable seal while preserving calibration integrity during repeated use. This class AS burette provides the accuracy and durability required for standardised laboratory procedures where certified volumetric glassware is essential.

Questions about Burette 25 ml cl-AS PTFE-plug CC
What is this article?
Burette 25 ml cl-AS PTFE-plug CC 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.
