Description
Volumetric flask, Class A, 25 ml, NS 10/19, Premium Line is a precision measuring vessel for accurate volumetric work in analytical, chemical and quality-control laboratories. Fabricated from high-quality borosilicate glass 3.3 and supplied with a PE stopper, it is developed in accordance with ISO 1042 and DIN 12664 and calibrated to contain (TC, In). Conformity with legal metrology requirements is shown by the official “DE-M (year)” symbol printed on each flask. A batch number is etched into the glass of every unit, and a batch certificate is included for free download. Offered by manufacturer Labbox within the Premium Line, these Class A flasks support reproducible preparation of standard solutions, dilutions and quantitative assays where tight volume tolerances are essential. The nominal volume is 25 ml (0,025 l). The pack contains 2 pieces; net weight is 0,085 kg. Borosilicate glass 3.3 provides the chemical and thermal resistance expected for routine laboratory handling while preserving Class A accuracy for everyday volumetric applications.

Questions about Volumetric flask class A with plastic stopper, 25 ml, mouth size 10/19, Premium
What is this article?
Volumetric flask class A with plastic stopper, 25 ml, mouth size 10/19, Premium is the article on this page. Luminix Health distributes Labbox 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.
