Description
Burette with PTFE spindle and Schellbach stripe, class AS, 50 ml is a high-capacity precision burette for titration and controlled volumetric dispensing in analytical workflows. It is made from high-quality borosilicate glass LBG 3.3 and adjusted for delivery (TD, Ex), with the batch number printed directly into the glass of each instrument. A PTFE spindle stopcock ensures reliable, chemically resistant regulation of flow, and the integrated Schellbach stripe supports clear meniscus observation for confident readings. The design complies with ISO 385, USP requirements and the German verification ordinance; conformity is shown by the official DE-M (year) symbol printed on every unit. A batch certificate can be downloaded free of charge. Nominal volume is 50 ml (0,05 l), accuracy class A/AS, net weight 0,243 kg. Offered as one piece from manufacturer Labbox (GLASSCO type), this class AS burette is well suited to routine and demanding laboratory titration where larger titre volumes, durable PTFE control and documented calibration status are required.

Questions about Burette with screw type needle valve PTFE stopcock, Schellbach type, Class AS, 5
What is this article?
Burette with screw type needle valve PTFE stopcock, Schellbach type, Class AS, 5 is the article on this page. Luminix Health distributes Labbox 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.
