Abstract

Conversion flask for use is an apparatus for the sequential performance of chemical processes on a sample of chemical material. The flask includes at least three capillary tubes and a large bore tube extending into the interior thereof for the introduction and withdrawal of various fluids. The capillary tubes are constructed to introduce a plurality of fine bubbles into a liquid within the flask to agitate the liquid and accelerate drying, to impinge chemicals on the walls of the flask, and to produce a spray onto the interior walls of the flask in proximity to its upper end to wash down the interior walls of the flask.
