Description
Automatic burette 25 ml brown glass with white 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. Robotic individual calibration helps prevent deviations from the stated nominal volume. Each burette carries the DE-M conformity mark and a batch number printed on the body; the matching batch certificate is available for download from the manufacturer website. A PTFE intermediate stopcock allows fast, accurate delivery, and the unit includes a PTFE needle-valve stopcock that needs no lubrication. Nominal values and lettering on brown automatic burettes are applied in white enamel for high visibility on the amber glass. This automatic burette from manufacturer ISOLAB Laborgeräte is delivered without bottle or bellows, which must be ordered separately. It supports titration and analytical laboratory applications that benefit from class AS accuracy and brown glass protection in a practical 25 ml capacity.
This article is part of Burettes, in Volumetric glassware.

Questions about burette - automatic - amber - PTFE intermediate stopcock - class AS - conf.
What is this article?
burette - automatic - amber - 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 Matériel de laboratoire.
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.
