Boiling Stones

Boiling Stones (Anti-Bumping Granules) – Laboratory Supplier South Africa | GLASSWORLD

Boiling Stones (anti-bumping granules, boiling chips) are small, porous inert granules added to liquids prior to heating to promote smooth, even boiling and prevent dangerous superheating and bumping. An essential laboratory safety consumable, boiling stones are used in distillation, reflux, and any heating procedure where sudden violent boiling could cause sample loss or injury. GLASSWORLD supplies boiling stones to laboratories and educational institutions across South Africa and sub-Saharan Africa.

Key Features

• Prevents superheating and bumping – Provides nucleation sites for smooth, controlled boiling
• Chemically inert – Does not react with or contaminate the sample being heated
• Porous structure – Traps air to provide consistent bubble nucleation throughout heating
• Single use – Should be replaced with fresh boiling stones for each new heating procedure
• Available in bulk quantities – Economical supply for high-throughput laboratory use

Applications

• Distillation procedures (simple, fractional, and vacuum distillation)
• Reflux reactions in organic chemistry
• Solvent evaporation and concentration
• Heating of aqueous and organic solutions
• University and teaching laboratory practicals
• Industrial and analytical chemistry laboratory use

Usage Note: Always add boiling stones to a cool liquid before heating. Never add boiling stones to a liquid that is already hot or near boiling, as this can cause violent bumping.

Available in bulk quantities. Supplied to laboratories, schools, and industrial customers across South Africa and sub-Saharan Africa. Request a quote for pricing or bulk orders.
