Vinyl-Coated Lead Rings Resist Chemicals and Reduce Breakage
Put Scienceware Vinyl-Coated Lead Rings on flasks before immersing them in water baths to help stabilize glassware and reduce breakage and chemical spills. Bright red (Round) or green ("C" Shape) Vikem® vinyl coating resists chemicals and won’t scratch flasks. Round Rings fit over flask and seat against its shoulder. C-Shaped Rings are flexible enough to be pulled apart to fit around vacuum filtering flasks, tubing and wide shapes.
