Bel-Art Ring Vinyl Coated Lead Open 1. This vinyl coated open ring is flexible and can be pulled apart to accommodate a wider vessel. The lead open ring is coated with Vikem vinyl a non-contaminating water-soluble petroleum-free petroleum product which is absorbed into the vinyl by evaporation during distillation procedures. The Vikem coating simultaneously prevents chemical attack and provides an additional degree of protection against corrosion. Each ring securely seats a syringe or lancet against a flame heat source etc. without damaging the vessel or the integrity of the connection. Rings are supplied with a stand for easy insertion into a flame source.
