Glas-Col 108B (LD-5C) Lead Donut Flask Stabilizer

Price is for one lead donut.

Ensure mid-range laboratory containers remain upright and secure with the genuine Glas-Col Lead Donut flask stabilizer. This versatile stabilizing ring balances weight and diameter perfectly. It acts as an optimal safeguard against tipping or floating when working with mid-sized glassware configurations in deep water baths or on moving shake benches.

Features:

Patented "Split-Ring" Design: The adjustable, open C-shape structure seamlessly fits around flask necks and side tubes. This makes it significantly easier to place than restrictive, fully closed circular weights.

Cushioned Surface Protection: Coated in a dense layer of orange/red chemically-inert PVC. The protective layer eliminates thermal shocks, cushions impact against delicate glass walls, and seals the heavy lead inner core to ensure a safe workspace.

Dependable Mid-Size Weighting: Adds substantial downward mass near the vessel's base, dampening localized vibrations from stirrers and offsetting buoyancy.
