Description
Weighting ring for flasks, Ø 74 mm, is a laboratory accessory designed to keep flasks submerged and stable during heating or incubation in a water bath. Made of metal with a protective PVC coating, the ring sits over the flask neck or body and adds controlled ballast so vessels do not drift or tip when buoyancy increases with temperature. The 74 mm diameter suits common round-bottom and similar flask formats used in routine wet-chemistry, sample preparation and temperature-controlled workflows. Supplied as a single piece with a net weight of 0,884 kg, it offers a durable, corrosion-resistant surface that withstands repeated contact with water-bath media. This weighting ring from manufacturer Labbox is a practical aid wherever floating glassware would interrupt heat transfer, mixing or timed incubations. Simple to place and remove, it supports safer, more reproducible bath work without altering the flask itself. Ideal for teaching labs, quality-control benches and research setups that rely on open water baths for gentle, uniform heating of reaction mixtures and standards.

Questions about Closed lead ring for flasks, Ø 74 mm
What is this article?
Closed lead ring for flasks, Ø 74 mm is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Other lab tools & accessories, inside Tools & accessories, in Labware.
This shelf is the bench tools that do not belong to a narrower rack: odd holders, small aids, pieces that complete a setup. The useful check is what the tool touches, and whether that contact adds a contaminant.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
