Hengar Boiling Granules – For Prevention of “Bumping” in Boiling Liquids 

In any laboratory procedure involving the boiling of a liquid, inert and insoluble Hengar Granules effectively prevent superheating with its attendant dangerous explosive vaporisation commonly known as “bumping.”

A few Hengar Granules in any boiling liquid permit a steady copious stream of bubbles to escape without this spasmodic splatter.
Evaporation or distillation proceeds quietly and smoothly. Sharper fractions result. Flask breakage is reduced, and watching time is minimised.

Froth is spread out evenly and does not climb the neck of the flask. Especially useful in boiling soap solutions and evaporating ethereal extracts of fat.
With Troemner B0343 Boiling Chips in the vessel, any gases formed are extracted from the liquid quickly and completely.

Insoluble, Hengar Granules cannot contaminate the liquid. They remain at the bottom of the flask or beaker, permitting the liquid to be readily poured off. After use, the granules are simply discarded. Hengar Granules are also available with a pure selenium coating, for use in the Kjeldahl digestion and distillation method of organic nitrogen determination.
