Description
Burette with straight stopcock and PTFE spindle, class AS, 50 ml, grad. 0,10 is a precision volumetric glass instrument for quantitative titration in analytical laboratories. It is made from high-quality borosilicate glass LBG 3.3 and adjusted to deliver (TD, Ex), with a nominal volume of 50 ml and fine 0,10 ml graduation for controlled reagent addition. A batch number is permanently printed into the glass of each burette, supporting clear lot traceability during routine and regulated work. The design follows ISO 385 and United States Pharmacopeia (USP) requirements. Conformity with legal metrology is shown by the official “DE-M (year)” mark printed on every unit, and a batch certificate is available as a free download. With a net weight of 0,248 kg, this class AS burette from manufacturer Labbox combines a straight stopcock and PTFE spindle for smooth, chemically resistant flow control. Supplied as one piece, it suits laboratories that need durable glass construction, documented accuracy class AS performance, and reliable delivery for aqueous and many common titration media in quality control and research settings.

Questions about Burette with screw type needle valve PTFE stopcock, Class AS, 50 ml, Grad. 0,10
What is this article?
Burette with screw type needle valve PTFE stopcock, Class AS, 50 ml, Grad. 0,10 is the article on this page. Luminix Health distributes Labbox 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.
