Description
Clear glass burette of borosilicate glass 3.3, class AS, with blue graduation and straight design is a precision volumetric instrument for accurate titration and liquid dispensing in analytical laboratories. This 50 ml model features a subdivision of 0,1 ml and an NS stopcock with PTFE plug, manufactured to ISO 385 and supplied with a batch certificate for full traceability. The borosilicate glass 3.3 construction delivers excellent chemical resistance and thermal stability, supporting reliable performance with a broad range of aqueous and organic reagents. Blue graduations ensure clear meniscus readability against the transparent body. Available as 1 pc from manufacturer Hecht, the straight configuration allows straightforward mounting in standard titration assemblies. The PTFE plug provides smooth, grease-free operation and a secure seal, minimising contamination risk during repeated use. Ideal for pharmaceutical quality control, environmental analysis, food testing and teaching laboratories that require class AS accuracy and reproducible volumetric results in everyday quantitative work.

Questions about Burettes , clear glass, Boro 3.3, Class AS, blue graduated , straight PTFE
What is this article?
Burettes , clear glass, Boro 3.3, Class AS, blue graduated , straight PTFE is the article on this page. Luminix Health distributes Hecht 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.
