W I T H SARGENT R A D I A N T HEATING M I C R O FURNACES (Pat. Pend.} Programming controls provide four different three phase programs, or two phase or single phase programs a t selected.
MAXIMUM UTILIZATION OF RADIANT TRANSMISSION INCREASES SPEED OF ANALYSIS Heats from room temperature to 700° C. in approximately seven minutes. Cools from 750° C. to room temperature in approximately t e n minutes. The automatic drive and programming device for the sample b u r n i n g furnace allow the operator to devote his attention to the preparation of a second sample during the period of burning the first. No ceramic cores o r insulating materials are used—power consumption is almost half that of conventional micro furnaces. This apparatus has been developed in consultation with micro chemical laboratories in which a large volume of elementary analysis is performed and w h e r e time is an important factor. The Sargent Combustion Apparatus is being employed with great success for halogen and sulphur as well as for nitrogen, carbon and hydrogen. The compact unit is installed in a metal case 24 inches long, 12 inches wide and 6% inches high, with a n aluminum top panel on which furnaces and controls are mounted. Quickly replaceable heating units are heavy gauge chromel wire. -— —
When furnaces are adjacent and adjusted to the same temperature, t h e internal tube temperature is uniform throughout the length of both furnaces. Length of long furnace, 7 inches; length of moving f u r nace, 2 inches; approximate m a x i m u m length of travel of moving furnace, 7 inches; m a x i m u m size of combustion t u b e accommodated, 14 millimeters OX>.; alternative rates of travel of moving furnace, 4 millimeters per minute and 12 p e r minute, respectively; m a x i m u m static time interval accommodated, 15 minutes; m a x i m u m operating t e m p e r a ture of furnaces, over 850 degrees centigrade; m a x i m u m power consumption of long furnace, 275 watts; m a x i m u m power consumption of moving furnace, 175 watts; m a x i m u m power consumption of complete unit, 600 watts.
