Description
Overflow volumetric flask 250 ml is a laboratory volumetric vessel intended for precise liquid handling and preparation. With a nominal capacity of 250 ml, the overflow design allows surplus liquid to leave the flask so that the calibrated working volume can be established consistently. The unit is supplied as a single piece and suits everyday analytical tasks in which overflow filling is preferred for volume setting. It is particularly relevant to biochemical oxygen demand (BOD) measurement setups and other water-quality laboratory procedures grouped under BSB measuring instruments. Produced by manufacturer Starke, the flask provides a practical 250 ml format for dosing, dilution and sample-preparation sequences that rely on repeatable liquid volumes. Distinguishing the overflow geometry from conventional volumetric flasks helps laboratories choose the correct vessel for each protocol. Integrate this 250 ml overflow volumetric flask into environmental, analytical and routine quality-control workflows where controlled overflow filling supports accurate and comparable volumetric work.

Questions about Overflow volumetric flask 250 ml
What is this article?
Overflow volumetric flask 250 ml is the article on this page. Luminix Health distributes Starke 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.
