  • SmartPresence and SmartLink Technologies Ensure Supervised Operation Protect your lab with patented SmartPresence and SmartLink technologies. These exclusive features automatically shut off the heater if no one is detected after a user set “time out” period has passed or the *Bluetooth® link between a paired mobile device is broken
  • SafetyHeat System Protects the Lab An industry-leading early detection system that uses two independent safety controls to continuously monitor the electronics and shut off heating before an overtemperature condition occurs.
  • Powerful, Consistent Stirring Performance Precise stirring from 60 to 1600 rpm is made possible by the design of a powerful motor, strong magnet and software controlled ramp rate, ensuring secure magnetic coupling for viscous applications.
  • Customized Performance for Precise Applications SmartHeat allows you to set the maximum temperature of the unit and SmartRate enables fast or slow temperature and speed ramp rates. The programming feature allows storage of 5 multi-step programs
