Heavy cast aluminum top distributes heat evenly. Accom modates several vessels... each receiving the same uni form temperature. Demand-type thermostat connected directly to top plate, senses any change and supplies full power until set temperature is reached. It then cycles to hold temperatures within ±3°C of set point. Maximum operating temperature is 371°C. Cast aluminum top has integral ribs . . . won't warp or buckle. Reflective baffles and thick insulation direct heat upward. Cooling air circulates around controls, extending control life and keeping bench tops cool. Perforated stainless steel case can support heavy loads. The rugged practicality of the
More specific method of measurement be cause fewer compounds exhibit fluorescing property · Fluorophors resulting from Fluorescamine are stable for several hours • As little as 10 to 40 nanograms of protein can be detected · Economically priced at $1375 · Call or write Gilson Medical Electronics, Inc.
