Description
Amber volumetric flask, conformity certified and class A, with NS poly stopper is a precision laboratory vessel made from borosilicate glass 3.3. With a nominal capacity of 250 ml and ground joint NS 14/23, the flask carries a white inscription and is manufactured in accordance with DIN EN ISO 1042. The amber glass body is paired with clear white markings for straightforward reading of the capacity designation during routine handling. Each flask is fitted with an NS poly stopper matched to the joint size for secure closure. Available in a pack of 2 pieces, this volumetric flask from manufacturer Hecht supports accurate preparation and dilution of solutions where class A volumetric glassware is specified. Conformity certification confirms compliance with the dimensional and volumetric requirements of the referenced ISO standard. Boro 3.3 construction together with the NS joint interface allows integration into standard laboratory glassware assemblies. The white inscription remains clearly visible on the amber surface, aiding identification when preparing, transferring or storing measured volumes in chemical and analytical workflows.

Questions about Flask, volumetric class 'A’, amber, white graduation, with plastic stopper, DIN
What is this article?
Flask, volumetric class 'A’, amber, white graduation, with plastic stopper, DIN is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
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.
