Product Description
EXTRACTION BOILING STONES
- 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.
