TAKES
"Extracto-Matic" flick of the control switch sets the separatory funnels on this mechanical extractor gently swinging through a 90° arc, the rocker oscillating at a rate of twenty times per minute. This motion—from horizontal to the vertical—assures the complete agita tion and intimate contact so necessary to full extrac tion. Eight 100 ml. extractions can be made at one time.
A
Liquid is introduced into the separatory funnel while the tube is in a horizontal position. As the opening always remains above the level of the liquid, no stopper is required during the entire oscillating period. Be cause no stopper is used, there is no pressure build-up. . . no vapor lock during drain-off. (Solution is drained through a stopcock.) >**%
