Description
Volumetric flask 100 ml GL18 amber graduated is a Class A precision vessel intended for the accurate preparation and dilution of solutions in analytical laboratories. Manufactured from DIFFICO brown amber glass, it effectively protects light-sensitive substances while the clearly marked ring graduation and content indication allow exact filling to the nominal volume. The neck features an ISO-standard GL18 thread and is supplied complete with a screw cap incorporating a PTFE-coated gasket for a reliable, chemically inert seal. This conformity-certified flask comes in a practical pack of 10 pieces and is produced by manufacturer Witeg for use in quantitative analysis, standard solution preparation, pharmaceutical compounding, and quality-control workflows. With a net weight of 0,058 kg, the robust design ensures long-term durability under routine laboratory conditions. Laboratories appreciate the combination of light protection, Class A tolerance, and secure closure when handling photosensitive reagents or working under controlled lighting. The amber volumetric flask supports reproducible results across a variety of chemical and biochemical applications requiring precise 100 ml volumes.

Questions about Volumetric flask 100 ml GL 18 brown graduated
What is this article?
Volumetric flask 100 ml GL 18 brown graduated 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.
