Description
Volumetric flask BLAUBRAND® ETERNA Class A in borosilicate glass Boro 3.3 is a precision laboratory vessel for accurate preparation and measurement of liquid volumes at the 1000 ml mark. Brown graduations aid clear reading and support work with light-sensitive media. The neck carries a standard ground joint NS 24/29 and is supplied with a polypropylene stopper for reliable closure during mixing, standing or short-term storage of solutions. Built to Class A accuracy requirements and marked DE-M, each flask from manufacturer Brand is accompanied by an individual ISO certificate documenting its volumetric performance. Boro 3.3 glass combines high chemical resistance with favourable thermal behaviour, making the vessel suitable for analytical chemistry, quality control, pharmaceutical laboratories and teaching environments. Typical uses include preparation of standard solutions, dilutions and volumetric work where calibrated Class A glassware is required. The unit is offered as a single piece, allowing flexible replenishment of bench stock without bulk over-ordering.

Questions about Vol. flask, BLAUBRAND-ETERNA, class A, 1000 ml, with NS 24/29 PP stopper, DE-M
What is this article?
Vol. flask, BLAUBRAND-ETERNA, class A, 1000 ml, with NS 24/29 PP stopper, DE-M is the article on this page. Luminix Health distributes BRAND 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.
