Description
Volumetric flask 200 ml class A according to USP is a precision glassware item designed for accurate volume measurement and preparation of standard solutions in regulated laboratory settings. Produced from borosilicate glass 3.3, it delivers the chemical resistance and thermal stability required for quantitative analytical work. The flask features an NS 14/23 ground joint together with a PE stopper in Diffico brown finish. Conformity-certified class A accuracy and USP compliance support reliable dilution and volumetric procedures. Manufacturer Witeg supplies each flask with a batch number and includes a batch certificate in every original packaging for complete traceability. Net weight is 0,082 kg. The 200 ml nominal capacity suits quality-control, pharmaceutical and research laboratories that prepare calibration standards or perform titrimetric analyses under USP-aligned requirements. The PE stopper seals the joint during mixing or storage, while the brown Diffico surface offers additional light protection for sensitive solutions. This configuration provides durable, reproducible class A performance for everyday precision liquid handling.

Questions about Volumetric flask, 200 ml, A, CC, ST 14/23, PE, USP
What is this article?
Volumetric flask, 200 ml, A, CC, ST 14/23, PE, USP is the article on this page. Luminix Health distributes Witeg 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.
