Description
Burette class B 50 ml with Schellbach stripe, lateral valve stopcock and PTFE spindle is a precision volumetric glassware item intended for accurate titration work. The 50 ml capacity is graduated in 0,1 ml increments and manufactured to class B tolerances, providing dependable delivery for routine analytical procedures. A Schellbach stripe improves meniscus readability, while the side-mounted valve stopcock fitted with a PTFE spindle ensures smooth, chemically resistant flow control and reliable shut-off. The complete unit weighs 0,089 kg net and is supplied in a pack of two pieces from manufacturer Witeg. This configuration is well suited to general laboratory titrations, educational use and quality-control applications where class B accuracy is sufficient. The combination of clear Schellbach reading aid and durable PTFE spindle stopcock supports consistent performance across repeated dispensing cycles without the need for grease on the valve.

Questions about Burettes class B 50 ml Schellbach valve stopcock
What is this article?
Burettes class B 50 ml Schellbach valve stopcock 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.
