Description:

The Isotemp 11-300-49SHP pairs a chemically-resistant 7 × 7 inch white-ceramic top with independent microprocessor heat and stir controllers that display both set-point and actual values in real time. A PID loop drives the 1000 W heater from 86 °F up to 1004 °F (30–540 °C), while a Hall-sensor feedback motor maintains smooth stirring from 60 to 1200 rpm even under viscous loads. The two-piece cast-aluminum chassis deflects spills away from electronics and includes a built-in mounting boss for rods or temperature probes; a remote 18-in stainless probe is supplied for closed-loop sample control. Safety features include an over-temperature cutoff and a bright red HOT TOP icon that remains lit until the ceramic cools below 122 °F. At 25 lb, the unit handles five-liter flasks yet sits just 7 in tall, leaving ample hood clearance. An easy-wipe membrane keypad withstands solvents, and cUL/CSA approvals simplify validation in regulated labs.

Economic Advantage:

Older analog hot plates forced technicians to dial-in temperature by trial and error. The 11-300-49SHP’s dual digital readouts, single-point calibration and included probe eliminate repeated solvent assays, cutting method-development time. Because the same chassis can function as a precise stirring mantle or a simple hot plate, labs buy one instrument instead of two and avoid the ongoing expense of separate mantles, saving hundreds of dollars over its service life.
