Description
Burette with straight PTFE stopcock and funnel opening, class A, 50 ml is volumetric glassware intended for precise titration and controlled liquid delivery in the laboratory. Manufactured to ISO 385 and adjusted for delivery (TD, Ex), this class A burette meets demanding accuracy requirements for quantitative analysis. The upper end features a funnel-shaped opening that simplifies and secures filling, reducing the need for separate funnels and lowering spillage risk. A straight polytetrafluoroethylene (PTFE) stopcock offers chemical resistance together with smooth, reliable flow control during titrant addition. With a nominal volume of 50 ml the instrument is a versatile choice for routine acid–base, redox and complexometric titrations in education, research and industrial quality control. The single-piece unit has a net weight of 0,170 kg and is supplied by manufacturer Labbox. A batch certificate is available free of charge for download, supporting traceability and documentation. Funnel top, PTFE key and class A performance together enable efficient, reproducible work with common aqueous laboratory reagents.

Questions about Burette with PTFE straight stopcock and funnel top, class A, 50 ml
What is this article?
Burette with PTFE straight stopcock and funnel top, class A, 50 ml 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.
