Description
Burette with lateral valve stopcock Schellbach class B 5 ml:0,02 is precision volumetric glassware for accurate titration and liquid dispensing in analytical laboratories. This class B instrument offers a 5 ml nominal capacity with 0,02 ml graduation intervals and incorporates a Schellbach stripe that sharpens meniscus visibility for reliable readings. A lateral valve stopcock fitted with a PTFE spindle provides smooth, chemically resistant flow control during routine titrations. Supplied as a pack of 2 pieces from manufacturer Witeg, the burette supports standard volumetric procedures where class B accuracy is required. The side-mounted stopcock arrangement allows convenient operation while the PTFE component resists sticking and attack by common reagents. Laboratories employ this glassware for acid-base, redox and complexometric titrations as well as teaching demonstrations of volumetric techniques. Clear Schellbach contrast reduces reading errors under ordinary lighting and promotes reproducible endpoints. Durable construction suits repeated use in quality-control, research and educational environments that demand dependable class B performance.

Questions about BURETTES, KLASSE B, 5 ML:0,02 LATERAL NE
What is this article?
BURETTES, KLASSE B, 5 ML:0,02 LATERAL NE 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.
