Description
Burette with straight PTFE stopcock and funnel opening, class A, 25 ml is a compact precision burette for accurate titration where smaller titrant volumes are preferred. Designed according to ISO 385 and adjusted for delivery (TD, Ex), the class A instrument delivers the volumetric accuracy expected in analytical and quality-control work. The upper end is formed as a funnel, enabling simple and safe filling without additional funnels or risk of spillage. A straight stopcock of polytetrafluoroethylene (PTFE) provides chemical resistance and smooth control of flow during dispensing. Nominal volume is 25 ml, making the burette well suited to micro-scale or intermediate titrations in teaching, research and industrial laboratories. Supplied as one piece with a net weight of 0,217 kg, the product comes from manufacturer Labbox. A batch certificate can be downloaded free of charge for documentation purposes. The combination of funnel top, PTFE key and class A tolerances supports efficient, reproducible titration workflows with aqueous and many common laboratory reagents.

Questions about Burette with PTFE straight stopcock and funnel top, class A, 25 ml
What is this article?
Burette with PTFE straight stopcock and funnel top, class A, 25 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.
