Product Description
Flasks that float, tip or drift in a water bath can spoil an incubation in seconds. These weighted rings sit over the neck of a vessel and hold it steady, whether it is resting on the bench, swirling on a shaker or partially submerged in a bath during a long run.
This listing is for catalog number HS8881A: Vinyl-Coated Lead Rings ("C" shape), fits 125 to 500 mL, Blue. Each ring is made of lead with a vinyl coating that will not scratch glassware or mark benchtops. The open C shape can be gently squeezed or spread for a closer fit around different necks. Four sizes are offered, covering flasks from 125 mL up to 4000 mL, with progressively heavier weights for larger vessels. LIGHT LABS stocks the Heathrow Scientific line, so racks, replacement parts and consumables are easy to reorder.
