Description
BLAUBRAND® titration apparatus with intermediate stopcock and PTFE key, without bottle, is a Class AS precision instrument for accurate volumetric analysis. It offers a nominal volume of 25 ml with 0,05 ml graduation and a blue Schellbach stripe that sharpens meniscus visibility for reliable endpoint detection. The side V-stopcock enables fine flow regulation while the intermediate PTFE-keyed stopcock delivers chemical resistance and secure sealing with common titrants. Conforming to DE-M marking, the unit supports standardised procedures in analytical chemistry, quality control and research. Supplied as a bottle-free model from manufacturer Brand, it integrates flexibly with existing reservoirs and stands. Suitable for Schilling-type rapid burettes and pellet-burette workflows, the design emphasises durability, clear scaling and repeatable performance during routine assays, method validation and high-precision quantitative work where Class AS tolerances are required.
This article is part of Burettes, in Volumetric glassware.

Questions about Aut.bur.BBR interm/PTFE-k.w/o bottle, 25 ml:0,05 ml Schellb. lat.safety stopc.
What is this article?
Aut.bur.BBR interm/PTFE-k.w/o bottle, 25 ml:0,05 ml Schellb. lat.safety stopc. is the article on this page. Luminix Health distributes BRAND 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.
