Description
Volumetric flask, trapezoidal, amber, conformity certified, class A, with NS poly stopper is a precision laboratory vessel for accurate preparation and dilution of standard solutions. Manufactured from borosilicate glass 3.3 with white inscription, it follows DIN EN ISO 1042 and is supplied with a matching NS poly stopper. The amber body protects light-sensitive media while the trapezoidal base improves stability on the bench. Nominal capacity is 25 ml with sleeve joint NS 10/19, supporting class A volumetric work in analytical chemistry, quality control and routine laboratory workflows. The flask is offered in a pack of 2 pc(s) from manufacturer Hecht and suits volumetric titration setups, stock-solution preparation and calibrated measuring tasks where certified class A accuracy is required. Clear white markings aid rapid reading of the meniscus under typical laboratory lighting. Its compact trapezoidal geometry combines a small footprint with reliable standing stability during filling, mixing and storage of prepared solutions.

Questions about Volumetric flask, trapezoidal, amber, class A, white graduation, with plastic
What is this article?
Volumetric flask, trapezoidal, amber, class A, white graduation, with plastic 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.
