Description
Burettes made of PMMA, 25 ml, are laboratory volumetric instruments for titration and controlled liquid delivery. Fabricated from polymethyl methacrylate (PMMA), they are specified to DIN class B with a nominal capacity of 25 ml, graduation intervals of 0,1 ml and a tolerance of 0,04 ml. Each burette is equipped with a straight PTFE plug stopcock that enables smooth, chemically resistant flow control during dispensing. Offered as a pack of 5 pieces from manufacturer Witeg, these transparent plastic burettes provide a lightweight alternative to glassware while keeping the liquid column clearly visible. Net weight is 0,054 kg per unit. They suit routine analytical titration, teaching laboratories and quality-control workflows where PMMA construction is appropriate. The DIN B accuracy class, fine 0,1 ml scale and PTFE stopcock together support reproducible volume delivery for aqueous and other compatible media in everyday laboratory practice, including setups associated with general and rapid-operation burette applications.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes (PMMA) 25ml
What is this article?
Burettes (PMMA) 25ml 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.
