VWR® Boiling Stones are granules of fused alumina designed to prevent bumping and superheating in boiling liquids during distillation or reflux operations. When added to a liquid before heating, these inert stones promote smooth, even boiling by providing nucleation sites for vapor bubble formation.
Ideal for use in chemical laboratories, they are chemically resistant, thermally stable, and easy to apply to a wide range of laboratory glassware and heating setups.
Key Features

Handling Notes
- Add to liquid before heating begins
- Do not add to hot liquids to avoid sudden boiling (violent eruption)
- Compatible with most standard laboratory glassware and solvents
VWR® Boiling Stones ('Anti-Bumping') are essential for safe and efficient boiling in laboratory settings. With high purity and consistent granule size, they ensure smooth heating processes and minimize the risk of splashing or sudden eruptions, making them a staple item for chemistry labs and distillation systems.
