250 g of aluminum oxide (Al2O3) granules.

Used in Fractional Distillations, Evaporations, Extractions, Refluxings, Condensations and Other Boiling Operations to Eliminate Bumping of Liquids.

The innumerable sharp projections of each granule increases the surface area on which vapor bubbles can form. This promotes a gentle stream of bubbles rising to the surface.

 

Highly effective in controlling distillation of liquids with low boiling points. Good in all boiling operations, except those with strong alkali's or concentrated sulfuric acid.
