Hotplate, Stirrer or Combo Hotplate/Stirrers

Benchmark Hotplates, Magnetic Stirrers and Hotplate-Stirrers feature an exceptionally durable, chemical resistant white ceramic work surface. Their space-efficient design (20.3 x 22.9cm [8 x 9"] footprint), makes them ideal for use on crowded benchtops and inside of bio-hoods.
Advanced microprocessor controls with convenient turn knobs allow quick, precise adjustment and maintenance of speed and temperature. Safety indicator LED's on the front panel indicate when the heating and/or stirring functions have been activated. The bases are sturdy, powder coated, cast-aluminum construction.
With a square 19cm (7.5") work surface, all three models are compatible with a wide variety of popular sizes of borosilicate glass beakers, flasks, bottles and other vessels. The Hotplate Magnetic Stirrer, Prod. No. 3235, comes complete with a support rod for mounting thermometers and temperature probes.
