Chemically inert carbon chips are microporous. They completely eliminate “bumping“ of either non-aqueous or aqueous boiling liquids. Chips are highly recommended for boiling operations such as condensations, extractions, evaporations, refluxings, fractional distillations, and many others. Smooth boiling is provided, either under vacuum or at atmospheric pressure. Decomposition or oxidation is prevented. Comes in 227 g bottle.
