Ohaus® Guardian™ 5000 Hotplate Stirrers

The Ohaus® Guardian™ 5000 is a reliable hotplate stirrer with exceptional safety features for everyday use.Designed for safety and simplicity in all research, academia, and industrial applications, the design of the Guardian™ 5000 ensures proper mixing and temperature control of the top plate or your sample when using the optional temperature probe. Heating models include a Single Point Calibration feature for multiple setpoints.

Unique Features:

  • 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 over temperature 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.
  • Easy to read LCD display with everything you need to know: The bright LCD display includes large temperature and speed settings, intuitive icons and a prominent hot top indicator—all designed to quickly and easily monitor performance from across the lab.
  • Designed for durability and reliability with the exclusive SmartHousing: The SmartHousing™ is chemical resistant with an innovative, easy-to-clean design that channels spills away from internal components and the angled control panel.
