Saint-Gobain Chemware PTFE Boiling Stones – 450g

Saint-Gobain Chemware PTFE Boiling Stones provide reliable, chemically inert nucleation sites for controlled boiling in laboratory distillation, reflux, and heating applications. Manufactured from virgin PTFE (polytetrafluoroethylene), these boiling stones offer exceptional chemical resistance and thermal stability, making them ideal for use with aggressive solvents, acids, and bases where traditional calcium carbonate or carborundum stones would degrade. The porous structure ensures consistent vapor release, preventing dangerous superheating and bumping during heating processes.
