Beschrijving
Volumetric flask, trapezoidal, borosilicate glass 3.3, with NS poly stopper serves as a reliable precision tool for exact liquid volume determination in analytical chemistry. Constructed from borosilicate glass 3.3, it offers strong resistance to chemical attack and thermal shock, making it suitable for a wide range of aqueous and organic media. The trapezoidal design enhances standing stability and facilitates precise meniscus reading, while the matching NS poly stopper closes the NS 7/16 ground joint securely. This conformity-certified 10 ml flask is ideal for preparing calibration standards, performing serial dilutions and carrying out quantitative assays in pharmaceutical, environmental and academic laboratories. Available as a single unit from manufacturer Hecht, the vessel combines proven glass quality with practical handling characteristics that support consistent results across repeated use. Its durable build maintains calibration accuracy even after frequent washing and autoclaving cycles typical of busy laboratory environments.

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.
