Description
Volumetric flask with glass stopper NS 7/16, clear, class A, 5 ml is precision laboratory glassware for accurate preparation and containment of defined liquid volumes. Made from high-quality clear laboratory glass with graduation and fitted with a matching glass stopper (NS 7/16), it meets class A tolerance requirements for demanding volumetric work. The 5 ml nominal capacity is ideal for small-scale standard solutions, sample dilutions, calibrations and quantitative transfers in analytical chemistry, quality control and teaching laboratories. Clear glass and graduation support reliable meniscus reading and visual checks of contents, while the glass stopper helps secure the prepared solution during handling and short-term storage. Supplied in a pack of 10 pieces, the set is practical for multi-user benches or stock replenishment. These flasks from manufacturer Dinkelberg are suited to workflows that specify class A volumetric glassware with an integral glass stopper. Typical uses include preparing working standards, serial dilutions and controlled volume make-up in research, industrial and educational settings that need compact 5 ml class A flasks with NS 7/16 glass stoppers.

Questions about Flask, volumetric with Glass stopper NS, 7/16, clear, Class A, 5ml, 10/PK
What is this article?
Flask, volumetric with Glass stopper NS, 7/16, clear, Class A, 5ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
