Description
DURAN® volumetric flask with beaded rim, without stopper seat, 5000 ml nominal capacity and without print is a large-volume laboratory vessel intended for precise volumetric work. Produced from borosilicate glass 3.3, the flask delivers the chemical durability and thermal performance expected in analytical, preparative and quality-control environments. The beaded rim design provides mechanical reinforcement at the neck while the absence of a stopper seat yields an open, easily accessible mouth for rapid filling and pouring. Clear glass without printed markings leaves the entire surface free for user-applied labels or inscriptions. Offered as a single piece from manufacturer Duran/DWK Life Sciences and bearing the DURAN® registered trademark, the 5 l flask is well suited to the preparation of bulk standard solutions, media and dilutions. Its generous capacity reduces the number of batches required for larger-scale laboratory procedures. The borosilicate composition withstands normal laboratory heating, cooling and cleaning routines. Packaging volume measures 0,028095 m³, supporting straightforward warehouse handling and shipment.

Questions about DURAN® Volumetric flask, without stopper bed, with beaded rim, 5000 ml, without
What is this article?
DURAN® Volumetric flask, without stopper bed, with beaded rim, 5000 ml, without is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
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.
