Glas-Col 108B (LD-7C) Lead Donut Flask Stabilizer

Price is for one lead donut.

Secure your valuable laboratory samples and prevent flotation accidents with the genuine Glas-Col Lead Donut flask stabilizer. This premium stabilizing weight is the industry-standard solution for anchoring glassware in water baths or securing top-heavy configurations on busy lab benches.

Features:

Patented "Split-Ring" Design: The open, flexible C-shape configuration allows you to easily slide the weight around flask necks, side-arm tubulations, and asymmetric glass setups where traditional closed rings fail.

Cushioned Surface Protection: Encased in a thick, vibrant red PVC coating that isolates the heavy lead center. This protective chemical-resistant layer ensures your glass is shielded from thermal shocks or scratches, while preventing any physical metal contact with lab surfaces.

Maximum Bench Stability: Heavyweight composition lowers the center of gravity of your glassware, minimizing tipping risks from vibrations, stirring mechanisms, or liquid buoyancy.
