Description
Pellet burette 50 ml class AS amber glass is a laboratory titration instrument designed for accurate and rapid volumetric work. Graduated 50:0,1 ml and conforming to class AS tolerances according to ISO 385, the burette is fabricated from amber glass to shield light-sensitive reagents. This model is supplied without an intermediate stopcock and features a lateral stopcock with an NS glass key, providing straightforward, reliable control of titrant flow. A 2 l amber-glass reservoir bottle is included, and the assembly is delivered without a pressure ball for convenient Schilling-style pellet-burette operation. Available as a pack of two pieces from manufacturer Witeg, the system delivers class AS precision for analytical chemistry, quality control and teaching laboratories. Amber glass construction of both the burette and the reservoir bottle reduces photochemical degradation of standard solutions, while the NS glass key offers a classic, chemically inert sealing interface. Net weight is 1,228 kg, making the unit suitable for everyday bench-top use where light protection and ISO-compliant accuracy are required.

Questions about Automatic burettes pellet 50 ml
What is this article?
Automatic burettes pellet 50 ml 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.
