Description
Automatic burette 50 ml clear with blue graduation is a precision volumetric instrument made from pre-vacuum calibrated 3.3 borosilicate glass tubing according to ISO 385 and calibrated to DIN/ISO class AS. Individual robotic calibration minimises deviations from nominal values. Each unit bears the DE-M conformity mark of the German weights and measures authority together with a batch number printed on the body surface; the corresponding batch certificate can be downloaded from the manufacturer website. An intermediate PTFE stopcock supports fast, accurate delivery, and the burette is supplied with a PTFE needle-valve stopcock that requires no lubrication. The clear glass body incorporates a Schellbach stripe for simple, precise observation of the meniscus line, while nominal values and inscriptions are printed in durable blue enamel. This automatic burette from manufacturer ISOLAB Laborgeräte is delivered without bottle or bellows, which must be ordered separately. It is well suited to titration and analytical laboratory workflows that demand reliable class AS performance and clear visual readout.
This article is part of Burettes, in Volumetric glassware.

Questions about burette - automatic - clear - PTFE intermediate stopcock - class AS - conf.
What is this article?
burette - automatic - clear - PTFE intermediate stopcock - class AS - conf. is the article on this page. Luminix Health distributes ISOLAB 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.
