Description
Amber volumetric flask borosilicate glass 3.3 with NS poly stopper is engineered for accurate liquid volume determination in analytical and preparative chemistry. The borosilicate glass 3.3 body ensures high chemical durability and resistance to temperature changes commonly encountered during heating or cooling steps. Amber colouring effectively protects light-sensitive samples and reagents from photochemical degradation. The included NS poly stopper forms a tight seal that limits evaporation and maintains solution integrity during storage or transport. With a nominal volume of 250 ml and conformity certification, the flask enables dependable preparation of calibration standards, buffer solutions and diluted samples. This single-piece laboratory item from manufacturer Hecht is well suited to pharmaceutical, environmental and research applications where precision and reproducibility are paramount. Robust construction allows repeated use under demanding cleaning and sterilisation regimes while preserving volumetric accuracy.

Questions about Volumetric flasks, borosilicate glass 3.3, amber, with interchangeable stopper
What is this article?
Volumetric flasks, borosilicate glass 3.3, amber, with interchangeable stopper is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
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.
