Digital Hotplates, Stirrers, and Hotplate Stirrers
  • Large white ceramic top plate
  • Digital speed and temperature control
  • Safety LED indicates hot surface
  • Available with stir capacities up to 15 L
  • Control actual temperature (with optional probe)

Benchmark Scientific Hotplates and Stirrers provide reliable performance and safe operation for everyday laboratory use.  With two sizes (7 inch or 10 inch) to choose from, each model features a durable, chemical resistant, white ceramic top plate and advanced microprocessor controls.  The constant monitoring system provides precise control of temperature (heating models only) with rapid heating and faster boiling times.  In addition, the powerful motor drive system of the magnetic stirrer ensures efficient mixing in larger vessels and more viscous samples.
 
Temperature and/or mixing speed can be viewed at all times on the large digital display and safety LED illuminates when the top plate temperature exceeds 50°C.  An optional external temperature probe can be used for applications that require precise temperature control.  The probe provides direct feedback to the microprocessor with adjustments for maintaining the selected sample temperature within ±1°C.  An optional clamp assembly (H3770-CS) is available for mounting thermometers, temperature probes, etc.

AccuPlate™ 
Digital Hotplates and Stirrers

  • Precise liquid temperatures and stirring speeds
  • Digital display and safety indicators
  • Angled front panel and large control knobs

AccuPlate digital hot plates and stirrers are powerful, versatile and easy to use. Every unit is built for consistent performance and long-term reliability. With three models to choose from, there is an AccuPlate hot plate and stirrer to meet your lab's needs.


Ceramic Durability and Resistance

Each AccuPlate is equipped with a Pyroceram® ceramic top plate that is extremely durable, easy to clean and is highly resistant to chemical attack. In addition, the ceramic plates can reach higher temperatures (rated to 550°C) than metal topped units and the white color makes it easy to view color changes in applications such as titrations. The AccuPlate Hotplate and Hotplate Stirrer models incorporate a powerful heating element positioned directly beneath the ceramic top plate. This provides optimal heat transfer to the plate and sample while minimizing heat transfer to the electronics and housing.


Acceleration Regulation

The Stirrer and Hotplate Stirrer utilize a powerful motor drive system paired with strong permanent magnets to ensure a consistent connection to the stir bar. The control software is designed to minimize stir bar decoupling by regulating the acceleration rate of the motor. The durable cast aluminum housing and angled faceplate protect the electronics in the event of an accidental spill. The Hotplate and Hotplate Stirrer models also feature a bright red "Hot Top" indicator to alert users that the ceramic top is too hot to touch - even if the heater is off, the light will remain on until the top has cooled to a safe temperature.
