Beschrijving
Pellet burette DIN-B 25 ml amber glass with PTFE stopcock is a precision titration instrument for laboratory volumetric analysis. Featuring a 25 ml capacity graduated at 0,05 ml, it conforms to DIN-B accuracy standards. The unit is fitted with a PTFE intermediate stopcock and a lateral valve stopcock that incorporates a PTFE spindle for durable, chemically inert control of liquid flow. A 2 litre amber glass reservoir bottle forms part of the assembly, which is delivered without a pressure ball. From manufacturer Witeg, the brown glass material safeguards light-sensitive media during both storage and use. Designed for rapid-operation burettes after Schilling, pellet burette methods and general titration setups, it enables efficient dispensing in analytical chemistry environments. Net weight is 1,224 kg. Available in packs of 2 pieces, the burette mates securely with standard NS laboratory joints for consistent, leak-resistant performance.

Questions about Autom. burettes, Pellet, 25ml:0,05 DIN-B
What is this article?
Autom. burettes, Pellet, 25ml:0,05 DIN-B is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labmateriaal.
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.
