Description
Pellet burette 25 ml Schellbach with PTFE stopcock is a precision titration instrument designed for rapid and reliable volumetric analysis in the laboratory. Graduated at 0,05 ml intervals and conforming to DIN class B, this pellet-style burette features a PTFE intermediate stopcock together with a lateral valve stopcock and PTFE cock for smooth, chemically resistant operation. The assembly includes a 2 l Schellbach reservoir bottle and is supplied without a pressure ball, allowing straightforward gravity-fed or manual filling. Clear Schellbach strip marking enhances meniscus readability during endpoint determination. Ideal for routine titrations, quality-control workflows and educational settings where durable glassware with inert PTFE components is required. Manufactured by Witeg, the unit combines classic pellet-burette geometry with modern stopcock materials. Net weight is 1,24 kg. Supplied as a practical two-piece pack, the burette supports efficient parallel work or spare capacity in busy analytical laboratories handling aqueous and many organic reagents.

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