Description
Volumetric flask with plastic stopper NS 29/32 is a clear glass laboratory flask designed for precise definition of larger liquid volumes at class B tolerance. With a nominal capacity of 2000 ml and a standard ground joint NS 29/32 sealed by a plastic stopper, it supports preparation of stock solutions, buffers and diluted samples where a secure closure and clear meniscus visibility are needed. The clear body allows confident reading of the calibration mark during filling to the mark, while the plastic stopper permits safe mixing by inversion without loss of contents. Class B volumetric glassware is appropriate for routine analytical, educational and quality-control tasks that demand dependable volume accuracy. Supplied in a pack of 6 pieces from manufacturer Dinkelberg, the set is suited to laboratories that regularly handle two-litre batches. The combination of defined joint size, plastic stopper and clear construction makes these flasks practical for everyday volumetric work in chemistry and related disciplines.

Questions about Flask, volumetric with plastic stopper NS 29/32, clear, Class B, 2000ml, 6/PK
What is this article?
Flask, volumetric with plastic stopper NS 29/32, clear, Class B, 2000ml, 6/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.
