Description
Volumetric flask, borosilicate glass 3.3, amber, with NS poly stopper, conformity certified is a small-capacity laboratory vessel for the accurate measurement and storage of light-sensitive solutions. This 5 ml flask is manufactured from borosilicate glass 3.3 in amber (brown) colour and is supplied complete with an NS poly stopper. Conformity certification ensures that the flask meets the volumetric accuracy requirements needed for analytical and quality-control work. The amber glass protects contents from light, while the poly stopper provides a secure, chemically resistant closure. Offered as a single piece from manufacturer Hecht, the flask is well suited for preparing and holding small volumes of standard solutions, reagents or samples in pharmaceutical, chemical and research laboratories. Borosilicate glass 3.3 delivers the expected chemical durability and thermal performance of volumetric glassware. The integrated NS poly stopper eliminates the need for a separate closure and supports reliable sealing during storage or transport. Pack size is 1 pc, allowing straightforward addition to any collection of precision volumetric flasks used for low-volume analytical procedures.

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.
