Description
Burette with straight PTFE stopcock, class A, 25 ml is a compact volumetric instrument intended for accurate titration and controlled liquid delivery in laboratory workflows. Designed in accordance with ISO standard 385 and adjusted to deliver (TD, Ex), it provides a nominal volume of 25 ml in accuracy class A for quantitative analytical work. The straight stopcock is executed in polytetrafluoroethylene (PTFE), offering smooth operation and broad chemical resistance during repeated open–close cycles. A batch certificate is available as a free download, supporting documentation needs in quality-controlled environments. Net weight is 0,130 kg, making the unit practical for everyday bench use beside standard titration setups. This class A burette from manufacturer Labbox is supplied as a single piece and fits applications where a 25 ml capacity, PTFE stopcock reliability, and ISO 385-aligned delivery tolerance are required. It is suitable for teaching labs, routine QC titration, and research protocols that depend on clear volume control without unnecessary complexity in the stopcock assembly.

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