V I S I T to the A m i n c o booth will acquaint you with the developments that are successfully and profitably meeting individual requirements i n re search and plant control laboratories the w o r l d over. Some of the instruments will b e i n operation at the exhibit. A m i n c o engineers will be i n attendance t o discuss your problems and the application o f instruments most likely to solve them satisfactorily.
M E W IMPROVED FORCED-DRAFT OVENS GUARANTEED FOR S YEARS
Instruments That Will Be Exhibited Constant Temperature Equipment: Baths Thermoregulators Relays Stirrers Refrigerated Constant Temperature Baths with Built-in Pumps for circulating liquids through other laboratory apparatus
Temperature maintained constant within =fc0.5°C Unusually high degree of tempera· rare uniformity throughout the working chamber (=±=0.25° C ) . Temperature range: room to 26θ° C. The above values are made possible by Aminco's method of heating, circulating and controlling the air. N e w features of con struction, operation and safety, including air flow and air-discharge controls that can be set for reproducible results. Heating elements are guaranteed against burnout» and thermoregulator against de fects in materials and workmanship, for a period o f five years. Bulletin 2102-NP
