Prevent catastrophic sample loss and glass breakage in agitated water baths with Heathrow Scientific Vinyl-Coated Lead Flask Rings. When buoyant Erlenmeyer flasks and volumetric glassware are submerged in heated or circulating water baths, they are highly prone to tipping over, resulting in ruined experiments and contaminated heating fluid. These heavy-duty lead weights easily slip over the neck of the flask, dropping the center of gravity and locking the vessel securely in an upright position.
To protect delicate glassware from scratching and to prevent the lead from oxidizing or contaminating the water bath, each ring is fully encapsulated in a thick, chemically resistant blue vinyl coating. The series offers both continuous Circular rings for standard immersion, and specialized 'C-Shape' rings that can be easily attached to vessels with side-arms or bulky tubing connections. Available in precise diameters and weights specifically calibrated to fit standard flask capacities ranging from 125 mL all the way up to massive 4000 mL vessels.
