Description
Schellbach burette class B with straight stopcock and PTFE key, 50 ml is a volumetric laboratory instrument intended for controlled liquid delivery during titration and related analytical work. It incorporates a Schellbach stripe that improves meniscus visibility and reading precision, together with a straight stopcock fitted with an NS-PTFE key. The nominal capacity is 50 ml and the burette conforms to accuracy class B. Each unit has a net weight of 0,089 kg and a gross weight of 0,089 kg. The product is offered in a pack of 2 pieces and originates from Germany (Baden-Württemberg). This burette from manufacturer Witeg belongs to the family of class-B Schellbach burettes used in educational, quality-control and routine laboratory environments. Its design supports straightforward integration into standard titration setups and pellet or rapid-operation burette configurations. The combination of the Schellbach scale and PTFE key provides a practical solution for everyday volumetric measurements where class-B tolerances are specified. Physical characteristics and packaging details align directly with the stated manufacturer data for reliable laboratory handling and storage.

Questions about Burettes class B, with short line gradua
What is this article?
Burettes class B, with short line gradua 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.
