Description
Burette class AS 50 ml with PTFE key and amber glass is a high-precision volumetric instrument for titration in chemical and analytical laboratories. It provides a 50 ml capacity graduated in 0,1 ml increments and complies with class AS accuracy standards. The burette features a straight stopcock fitted with a PTFE key for excellent chemical resistance and smooth operation, while the brown-tinted amber glass protects light-sensitive media from photochemical effects. Calibrated (KB) for reliable volumetric work, it is suited to demanding titration protocols. These amber glass burettes from manufacturer Witeg are supplied in packs of 2 pieces, each with a net weight of 0,088 kg. The PTFE key requires no lubrication and withstands aggressive reagents that can attack conventional glass keys. Combined with the light-protective brown colouration, the design supports accurate and safe handling of a broad range of titrants. Laboratories engaged in quality control, research or teaching benefit from the durable construction, precise flow control and class AS performance of this burette for everyday analytical workflows.

Questions about Burettes class AS 50 ml PTFE-plug amber stained
What is this article?
Burettes class AS 50 ml PTFE-plug amber stained is the article on this page. Luminix Health distributes Witeg 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.
