Description
Sedimentation vessels according to Imhoff without stopcock are specialised glassware used to measure settleable solids in aqueous samples. Fabricated from borosilicate glass 3.3 in accordance with DIN 12 672, the vessels are graduated from 0-1,000 ml with durable white markings. The classic Imhoff cone geometry facilitates sedimentation of suspended particles under gravity. Absence of a stopcock makes these vessels suitable for straightforward volumetric reading of the settled layer after the standard standing time. Supplied in cartons of 2 pieces from manufacturer Marienfeld, they form part of the sedimentation-vessel and settling-cylinder ranges. Laboratories engaged in water-quality control, wastewater monitoring and related environmental analyses employ these vessels for routine Imhoff sedimentation determinations. Borosilicate glass 3.3 offers the necessary resistance to common laboratory reagents and cleaning regimes. Clear white graduations spanning the full 0-1,000 ml range support accurate recording of sediment volume in millilitres.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Sedimentation cones acc. to Imhoff, without stopcock
What is this article?
Sedimentation cones acc. to Imhoff, without stopcock is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Measuring cylinders, inside Volumetric glassware, in Labware.
A measuring cylinder is the tall graduated vessel for a volume that does not need volumetric-flask accuracy. Class A and class B differ in tolerance. Reading the bottom of the meniscus, at eye level, is part of using it.
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.
Which category should I open next?
