Hotplate+Stirrer option
Benchmark hotplates, stirrers and hotplate-stirrers feature an exceptionally durable, chemical resistant white ceramic work surface. Their space-efficient
design (8 X 9 in. 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. With a square 7.1 in 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 model (H4000-HS) comes complete with a support rod for mounting thermometers and temperature probes.

  • Ceramic work surface, 7.1 x 7.1 in.
  • Stir speed from 60 to 1500 rpm
  • Temperature control up to 380°C
  • Three models: heat-stir, heat only or stir only
