Description
Volumetric flask 10 ml, class A with batch certificate, NS 7/16 ground joint and PE stopper is a precision laboratory vessel for accurate volumetric work. Manufactured from borosilicate glass 3.3, this Diffico brown flask combines chemical resistance with thermal stability suited to analytical and preparative procedures. It meets class A accuracy requirements and is conformity certified. Every flask carries a batch number, and a batch certificate is supplied with each original packaging unit, supporting traceability in regulated environments. The polyethylene stopper seats securely in the NS 7/16 joint to limit evaporation and contamination during solution preparation or temporary storage. These flasks from manufacturer Witeg are well suited to preparing standard solutions, performing dilutions and conducting quantitative analyses in chemical, pharmaceutical and quality-control laboratories. The Diffico brown colouration offers protection for light-sensitive contents. With a net weight of 0,01 kg, the 10 ml capacity enables economical use of reagents while maintaining reliable volumetric performance. Supplied in packs of 10 pieces, the flasks provide a practical stock of certified class A glassware for routine and high-precision applications.

Questions about Volumetric flask, 10 ml, A, CC, ST 7/16, PE
What is this article?
Volumetric flask, 10 ml, A, CC, ST 7/16, PE 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.
