Description
Burettes class AS, SB 25:0,05 ml, conformity certified are high-accuracy volumetric glassware items intended for precise titration and quantitative laboratory analysis. Constructed from DURAN® borosilicate glass 3.3, they offer the durability and chemical resistance expected in daily analytical use together with class AS volumetric performance. Blue graduation markings, a Schellbach stripe and main-point ring division facilitate unambiguous meniscus observation, and a lateral glass stopcock provides smooth, controlled delivery of titrant. The nominal volume of 25 ml is subdivided at 0,05 ml intervals in line with DIN EN ISO 385. Every unit includes a conformity declaration according to DIN 12600 and is marked with dated batch identification to support documented quality and audit requirements. Supplied by manufacturer Hirschmann in packs of 2 pieces, these burettes serve research, quality-control, industrial and educational laboratories that need reliable class AS titration instruments with full conformity certification.

Questions about BURETTES CL. AS CC 25:0,05 ML, SB, LATERAL STOPCOCK
What is this article?
BURETTES CL. AS CC 25:0,05 ML, SB, LATERAL STOPCOCK is the article on this page. Luminix Health distributes Hirschmann 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.
