Saint-Gobain Chemware PTFE Boiling Stones

The Saint-Gobain Chemware PTFE Boiling Stones enhance laboratory processes by promoting gentle and efficient boiling. These stones are particularly effective in preventing overheating, even when working with highly volatile liquids. Their design makes them ideal for continuous extraction methods, as they significantly reduce the risk of "bumping" during reflux and distillation procedures.

The chemical resistance of these boiling stones is a key feature, as they remain unaffected by substances including acids, hydrocarbons, ketones, esters, alcohols, and alkalis. This inert nature ensures they maintain their effectiveness across various chemical environments. Importantly, they show no trace of face acidity or alkalinity, preserving the purity of the solutions they're used in.

Laboratory glassware remains protected when using these stones, as they won't scratch or abrade surfaces and leave no residue behind. The stones can withstand temperatures up to 550°F (288°C), making them suitable for a broad range of heating applications in the lab.
