Description
Weighting rings are laboratory accessories used to secure vessels during water-bath work. Manufactured from lead with a durable blue vinyl coating, they provide reliable mass while protecting glassware and bench surfaces from scratches and marks. Simply place a ring around the vessel neck to prevent flasks from floating or tipping over in the bath. The open C-shape allows flexible positioning and suits vessels with side arms or lateral connections. Very good chemical and thermal resistance supports everyday laboratory conditions. Each ring is individually packed for convenient handling and storage. These weighting rings from manufacturer Marienfeld are a practical aid for heating baths, incubation setups and other wet-lab workflows where stable vessel placement is essential. The robust vinyl finish withstands repeated use and helps keep working surfaces clean without compromising the lead core’s weighting performance.

Questions about Lead rings
What is this article?
Lead rings is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Stationery, books & lab notebooks, inside Tools & accessories, in Labware.
A laboratory notebook is the bound record of what was done, in an order that cannot be quietly rewritten. Loose paper is not that record. The page has to survive the bench, including a splash.
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.
