Description
Volumetric flask without stopper, clear, class A, 500 ml provides a larger calibrated volume for laboratories that prepare bulk standards, stock solutions, and multi-sample dilutions with defined accuracy. The clear flask body allows easy content inspection and reliable meniscus observation at the graduation mark during volumetric make-up. Class A designation places the item in the higher-accuracy volumetric category preferred for quantitative analytical work, while the absence of a supplied stopper leaves closure choice open to the end user. A pack of 10 pieces supports continuous bench use at the 500 ml capacity without frequent reordering of single units. Manufactured by Dinkelberg and originating from the Czech Republic, these flasks align with standard lab material requirements in education, quality control, and research settings. They are suited to solution preparation ahead of titration, spectroscopic work, or other methods that depend on known volumes, as well as to instructional environments teaching proper volumetric handling. Flexible pairing with laboratory stoppers helps match chemical compatibility and storage needs across different protocols while retaining the familiar Class A volumetric flask geometry.

Questions about Flask, volumetric without stopper, clear, Class A, 500ml, 10/PK
What is this article?
Flask, volumetric without stopper, clear, Class A, 500ml, 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.
