Description
Volumetric flask without stopper, clear, class B, 5 ml is laboratory glassware intended for accurate preparation and measurement of defined liquid volumes in analytical and routine work. Made from clear glass to class B tolerance, it supports volumetric procedures where a stopper is not fitted or is chosen separately by the user. The 5 ml nominal capacity is well suited to small-scale standard solutions, sample dilutions, calibrations and quantitative transfers in chemistry, quality-control and teaching laboratories. Clear walls aid visual inspection of the contents and reliable meniscus reading during fill-to-mark operations. Supplied as a practical pack of 10 pieces, the set is convenient for multi-user benches, teaching kits or stock replenishment. These flasks from manufacturer Dinkelberg integrate readily into everyday volumetric workflows and are appropriate wherever class B accuracy is specified. Without stoppers as delivered, they leave closure selection open to the laboratory protocol. Typical uses include preparing working standards, serial dilutions and controlled volume make-up in research, industrial and educational settings that require dependable class B volumetric glassware in a compact 5 ml format.

Questions about Flask, volumetric without stopper, clear, Class B, 5ml, 10/PK
What is this article?
Flask, volumetric without stopper, clear, Class B, 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.
