Ohaus Guardian™ 7000 Hotplate Stirrers

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.

SmartPresence™ and SmartLink™ technologies ensure supervised operation by automatically shutting off the heater if no one is detected after a user set “time out” period has passed.

SafetyHeat™ system protects the lab with 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 with SmartHeat™ which 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.
