Spark chamber puiser system accepts ± 2 5 0 - m v . pulses from any commer cial logic module and delivers up t o five simultaneous pulses with ampli tudes of 2 to 2 0 kv. and a delay of approximately 3 0 nsec. Model 0 2 2 is designed for driving spark chambers or several Model O i l fanouts. The spark gap is in an enclosure supplied with gas fittings t o provide an inert atmosphere for safety purposes. The system may be pressurized to shorten both the delay and rise times. Sci ence Accessories Corp., Southport, Conn. 414

Electrophoresis
The Camag high voltage electro phoresis system gives rapid separations (20 minutes for most metabolic screen ing runs). The cooling system, using tap water, eliminates heat buildup with out eluting specimens by buffer evapo ration. The high resolution permits separations of inorganic ions and other low molecular weight substances. The high voltage eliminates specimen de salting. Gelman Instrument Co., P. O.
