Description
Pellet burette 25 ml DIN B is an amber-glass titration burette fitted with a PTFE spindle stopcock for smooth, chemically resistant control of titrant flow. Graduated 25 ml with 0,05 ml division and configured without an intermediate stopcock, it employs a lateral valve cock with PTFE spindle for reliable sealing in Schilling-type pellet burette applications. Amber glass reduces light exposure for photosensitive solutions. The assembly includes a 2 l reservoir bottle and is supplied without a pressure bulb, enabling gravity or system-driven feed from the reservoir for efficient multi-sample titration sequences. Net weight is 1,186 kg. Offered by manufacturer Witeg, this DIN B class instrument suits analytical chemistry, quality control, and teaching laboratories that prefer PTFE contact surfaces at the stopcock for broader chemical compatibility. Packaged as 2 pieces, it provides capacity for dual workstations or spare readiness on the titration bench while maintaining consistent volumetric performance.

Questions about Pellet burette 25 ml DIN-B amber glass
What is this article?
Pellet burette 25 ml DIN-B amber glass 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.
