Beschrijving
Volumetric flask, borosilicate glass 3.3, blue graduated and conformity certified with NS poly stopper provides a reliable vessel for precise volumetric work and preparation of standard solutions. Constructed from borosilicate glass 3.3, it offers the chemical durability and thermal performance expected in everyday laboratory practice. Blue graduation marks clearly show the nominal 25 ml capacity, and conformity certification underpins use where documented volume accuracy is required. An NS poly stopper closes the NS 12/21 ground joint, helping retain contents during shaking, dilution or temporary storage. This single-piece flask from manufacturer Hecht is suitable for titration, dilution series and general sample preparation in chemical, pharmaceutical and research settings. The sturdy glass construction tolerates normal laboratory cleaning cycles and handling. It fits standard workflows that depend on certified volumetric glassware for consistent 25 ml volume definition.

Questions about Maatkolven, borosilicate glas 3.3 conformiteitsgecertificeerd, met
What is this article?
Maatkolven, borosilicate glas 3.3 conformiteitsgecertificeerd, met is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Maatkolven, inside Volumetrisch glaswerk, 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.
