Description
Replacement spindle in PTFE with lock is a valve-stopcock spare part for laboratory burettes from 2 ml to 50 ml fitted with a straight or lateral V-stopcock. The PTFE spindle restores reliable sealing and smooth operation of the stopcock assembly when the original component is worn or damaged. A securing feature helps keep the spindle correctly seated during routine titration and volumetric work. Suitable for glass burettes used in analytical chemistry, quality control and teaching laboratories, this spare part supports continued accurate liquid dispensing without replacing the entire burette. The component is supplied as a single piece and is intended for direct exchange on compatible Brand burette stopcocks. Compact packaging and low net weight make it practical for instrument maintenance kits and spare-parts stores. Choose this PTFE replacement spindle when maintaining burettes that use straight or side-mounted V-stopcocks in the 2–50 ml range.

Questions about Needle-valve stopc./spare spindle reten., dev./snap ring f. valve open. 0-2,5 mm
What is this article?
Needle-valve stopc./spare spindle reten., dev./snap ring f. valve open. 0-2,5 mm 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.
