Protect your lab with patented SmartPresence™ & SmartLink™ technologies. These exclusive features automatically shut off the heater if no one is detected after a user set "time out" period has passed.

An industry-leading early detection system that uses two independent safety controls to continuously monitor the electronics and will shut off heating before an overtemperature condition occurs. 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.
