Low noise design with large dust capacity for heavy duty applications. adapter, and a vacuum applied to the side arm of the filter flask (see left). Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). If smaller quantities are to be filtered the Hirsch funnel (see left and below) and a small filter paper should be used instead. Hold the open end of the hose over one of the return jets to fill it with water and blow out all the air in the hose. Order online at Screwfix.com. Once it is totally dry (no more bubbling from the solid) remove the flask from the vacuum line and scrape the sides clean with a spatula. 2 000 new building blocks are synthesized monthly.
