Class AS burette BG 25:0,05 ml is a precision volumetric instrument made from DURAN® borosilicate glass 3.3 with white graduation for accurate titration work. This brown glass model offers a nominal volume of 25 ml and a scale division of 0,05 ml, featuring main point ring division for clear readability. It is fitted with a straight valve stopcock and PTFE spindle that allows controlled, smooth dispensing of titrants while providing chemical resistance. Manufactured in accordance with DIN EN ISO 385, the burette includes a conformity declaration according to DIN 12600 and dated batch identification to support traceable class AS performance. The amber glass construction helps shield light-sensitive solutions during analytical procedures. Supplied in a pack of 2 pieces from manufacturer Hirschmann, this durable glassware is suited to routine volumetric analysis in quality-control, research and teaching laboratories. Borosilicate glass 3.3 delivers the thermal and chemical stability required for repeated laboratory use under standard conditions.
This article is part of Burettes, in Volumetric glassware.

Questions about BURETTES AS AG 25:0,05 ML, STRAIGHT STOPCOCK PTFE SPINDLE
What is this article?
BURETTES AS AG 25:0,05 ML, STRAIGHT STOPCOCK PTFE SPINDLE is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labmateriaal.
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.
