Product: Laboratory Metal Ring Clamp — closed-ring design for ring holders and displays Key benefits Reliable support for glassware: The closed metal ring provides a stable platform for beakers, funnels and other vessels during experiments. Durable, corrosion-resistant finish: Manufactured with an oxidation-resistant metal surface for long-term laboratory use. Simple, practical design: A straightforward clamp structure that is easy to attach and adjust, reducing setup time and improving workflow. Versatile compatibility: Designed to work with standard ring holders, retort stands and display assemblies commonly used in chemistry labs. What it does and why you need it Holds glassware securely over heat sources or work surfaces so you can heat, filter or suspend samples safely and consistently. Replaces improvised supports and reduces the risk of slips or poor alignment during experiments. Durable construction and an oxidation-resistant finish keep the ring functional in humid or corrosive lab environments. Features and specifications Closed metal ring form for continuous support around vessel bases Oxidation-resistant metal finish for extended service life Simple clamp design for quick attachment to ring stands or holders Suitable for routine laboratory tasks and educational lab use Typical applications (real lab scenarios) Heating: Hold beakers or flasks above a Bunsen burner or hot plate for controlled heating and reactions. Filtration: Support a funnel and filter paper over a receiving flask for gravity filtration or solvent transfer. Sample preparation and titration: Suspend flasks or glassware during titrations, sample transfers, or evaporation setups. Performance and compatibility notes Intended for use with common laboratory ring holders, retort rods and clamps; fits standard lab setups for teaching, research and general-purpose chemistry work. Simple construction makes inspection, cleaning and storage straightforward. Practical advantages Quick to install and adjust, helping speed routine lab procedures Robust enough for repeated daily use in classrooms, research labs and industrial settings A practical, low-maintenance accessory to improve safety and consistency in glassware handling
