Beschrijving
Pellet burette 25 ml DIN-B with Schellbach stripe and PTFE spindle is a precision volumetric instrument for rapid laboratory titrations. It offers a 25 ml capacity with 0,05 ml graduation intervals and conforms to accuracy class DIN-B. The design omits an intermediate stopcock and instead uses a lateral valve stopcock fitted with a PTFE spindle for smooth, chemically resistant flow control. A Schellbach stripe runs along the burette tube to improve meniscus visibility and reading precision during endpoint determination. The complete assembly includes a 2 l reservoir bottle and is supplied without a pressure ball, supporting continuous refill operation typical of Schilling-type pellet burettes. This configuration from manufacturer Witeg is well suited to analytical chemistry, quality-control titration and educational laboratories that require reproducible dispensing of aqueous or dilute reagent solutions. The compact layout facilitates bench-top installation while the PTFE spindle ensures long-term sealing performance. Packaged as a set of two complete units, the product provides ready capacity for parallel workstations. Net weight is 1,188 kg.

Questions about Autom. burettes, 25 ml:0,05, DIN-B, wi
What is this article?
Autom. burettes, 25 ml:0,05, DIN-B, wi 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.
