Description
Volumetric flask, amber glass, LBG 3.3, Class A, with plastic stopper, 50 ml, is a precision measuring vessel made from borosilicate glass 3.3 for accurate volumetric work. The brown amber glass protects light-sensitive contents while the polyethylene (PE) stopper seals the neck securely. Designed according to ISO 1042 and DIN 12664 and calibrated to contain (TC, In), this Class A flask supports reliable preparation of standard solutions, dilutions and analytical reagents. The nominal volume is 50 ml with ground joint size 12/21, making it suitable for routine quantitative chemistry, quality control and pharmaceutical laboratory workflows. Supplied in a pack of 2 pieces from manufacturer Labbox, each flask has a net weight of 0,126 kg. A batch certificate is available as a free download to support traceability and documentation needs. The combination of LBG 3.3 borosilicate construction, amber colouration and PE closure provides a durable, light-protective option for laboratories that require Class A volumetric accuracy without compromising chemical resistance or handling convenience in everyday use.

Questions about Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 50 ml, 12/2
What is this article?
Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 50 ml, 12/2 is the article on this page. Luminix Health distributes Labbox 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.
