Beschrijving
Volumetric flask in trapezoidal form manufactured from borosilicate glass 3.3 provides a stable, precision vessel for preparing small defined volumes in the laboratory. Fitted with an NS poly stopper, the flask maintains a secure seal that helps protect standards and dilutions from evaporation or airborne contamination. Borosilicate glass 3.3 offers the expected chemical durability and thermal resistance for routine aqueous work and many common solvents. The trapezoidal profile lowers the centre of gravity relative to classic flask shapes, improving bench stability during filling, mixing and storage. This conformity-certified model from manufacturer Hecht is supplied as a single piece and is well suited to analytical, pharmaceutical and teaching environments where compact volumetric glassware is required. The NS 7/16 poly stopper matches the ground neck for repeatable closure, while the clear glass body supports visual inspection of contents and meniscus reading. Robust walls tolerate normal washing and handling cycles associated with daily laboratory use.

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