OHAUS Guardian 7000 Hotplate Stirrers are designed with outstanding safety features and superior heating and mixing performance. The SmartHousing is chemical resistant with an innovative, easy-to-clean design that channels spills away from internal components and the angled glass control panel. The bright LCD display includes intuitive icons, temperature, speed and time settings – all designed to monitor performance from across the lab.

Protect your lab with 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 – 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.

Precise stirring from 60 to 1600 rpms on the Ohaus Guardian 7000 is made possible by the design of a powerful motor, strong magnet and software controlled ramp rate; ensuring secure magnetic coupling for viscous applications.
