Description
Volumetric flask, PFA, class A with screw cap is a high-purity laboratory measuring vessel with a nominal volume of 25 ml (0,025 l), manufactured from perfluoroalkoxy alkane (PFA) and supplied with a matching PFA screw cap. Class A accuracy supports precise volumetric preparation of standards, dilutions, and analytical solutions where tight tolerance and chemical inertness are required. PFA construction provides outstanding resistance to aggressive acids, bases, and organic solvents, together with a smooth, non-stick surface that minimises sample adhesion and simplifies cleaning. The integrated PFA screw cap secures contents during mixing, storage, and transport. Offered in a pack of 2 pieces from manufacturer Vitlab, these flasks suit trace analysis, ultratrace work, and applications demanding low metal blank values. Gross weight is approximately 0,03 kg per unit. Ideal for research, quality control, and specialised analytical laboratories that rely on chemically inert, class A volumetric glassware alternatives for demanding sample matrices.

Questions about Volumetric flask, PFA, ''class A'', 25 ml, with screw cap, GL 18
What is this article?
Volumetric flask, PFA, ''class A'', 25 ml, with screw cap, GL 18 is the article on this page. Luminix Health distributes Vitlab 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.
