Heathrow Scientific® Lead Rings

Heathrow Scientific® Lead Rings are designed to stabilize glassware and lab vessels securely on the benchtop or in water baths. These vinyl-coated lead rings offer a flexible and protective solution for preventing tipping or movement of flasks, beakers, and cylinders during procedures.

The durable vinyl coating protects both your labware and benchtop from scratches, marks, or damage, while the C-shape design option allows for slight manual adjustment to accommodate a range of vessel sizes.

Ideal for labs using water baths or uneven surfaces, these stabilizing rings improve safety and efficiency during experiments. Sold in vibrant blue, they offer easy visibility in busy workspaces.
