Plain Hengar Granules 10kg

Non-selenized

   These granules are made of a high purity, white amphoteric alundum.  They are extremely hard, and while they do have a porous surface they will not crumble or "powder" when used.  They are a four mesh granule size, and have a specific gravity of 3.97.

   In any laboratory procedure involving the boiling of a liquid, inert and insoluble, Hengar Granules effectively prevent super-heating with its attendant dangerous explosive vaporization, commonly known as "bumping".

   By adding  a few Hengar Granules to a boiling liquid, a steady and copious stream of bubbles is permitted to escape without the spasmodic splatter.  Distillation and evaporation can proceed quietly and smoothly, and sharper fractions will result.  Becauseof the reduced boiling volatility, flask breakage is reduced and time spent watching the boiling process is minimized.  In addition to the steady stream of bubbles, any froth that is produced spreads out evenly within the available space of the flask, and does not climb the neck of the flask.  Any gases formed get are also extracted from the liquid, quickly and completely.

   As they are insoluble, Hengar Granules are unable to contaminate the liquid.  They stay on the bottom of the flask or beaker, allowing for liquid to be easily poured out without having to worry about using a mesh strainer to keep the granules in the boiling container.  After being used, the granules can be discarded using standard laboratory procedures.

   Our granules are also available with a pure selenium coating, allowing them to be used in the Kjeldahl digestion and distillation method of organic nitrogen determination.
