Hengar Granules with a pure selenium coating, for use in the Kjeldahl digestion and distillation method of organic nitrogen determination to prevent bumping.
Hengar Selenized Granules
High purity, amphoteric alundum, specially treated with selenium for use in determination of amino and cyanide nitrogen. Four mesh granule size, iridescent bluish black color.
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 vaporization 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. 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.
