Description
Automatic Schilling burette class AS with blue graduation and Schellbach stripe, 25 ml, is a precision volumetric instrument intended for accurate titration and quantitative liquid dispensing. Manufactured from pre-vacuum calibrated 3.3 borosilicate glass tubing according to ISO 385 and calibrated to DIN/ISO class AS, every unit carries the DE-M conformity marking issued by the German weights and measures authority. Individual calibration by automatic robots reduces possible deviations from nominal values. Conformity marking and batch number are printed directly on the body surface; the corresponding batch certificate is available for download. The clear glass tube is equipped with a Schellbach stripe that enables straightforward and precise reading of the meniscus line. Nominal values and inscriptions appear in blue enamel for lasting contrast. Delivery includes a PTFE needle-valve stopcock that needs no lubrication and ensures controlled, drip-free operation. This automatic burette from manufacturer ISOLAB Laborgeräte is supplied as one piece and is well suited to analytical, quality-control and teaching laboratories requiring reliable volumetric performance.

Questions about burette - schilling - automatic - clear - Class AS - conformity batch certified
What is this article?
burette - schilling - automatic - clear - Class AS - conformity batch certified 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.
