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. Evaporation or distillation proceeds quietly and smoothly. Sharper fractions result. Flask breakage is reduced and watching time is minimized. 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 Hengar Granules 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.

An economical way to produce hydrogen sulfide gas for use in qualitative analysis and the general chemistry laboratory.

Aitch-Tu-Ess is a dry mixture of sulfur, a highly condensed hydrocarbon, and an inert dispersal agent. The sulfur and the hydrocarbon are combined in the proportion most conducive to maximum yield of H2S gas, while the inert dispersal agent serves to support the reactants.

This material, when heated, produces H2S gas which is highly toxic. Heating and all experiments should be conducted under a fume hood. The threshold limit value of H2S is 10 parts per million or 15 milligrams per cubic meter.

Directions for use are supplied with each package.
