PR1MA Hotplates, Magnetic Stirrers, and Hotplate-Stirrers

  • 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

PR1MA 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 (MS-1500) comes complete with a support rod for mounting thermometers and temperature probes.
