Ohaus Guardian 3000 e-G31HS07C Hotplate Stirrer, 115V

The Ohaus Guardian 3000 Series Hotplate Stirrers are designed for economical heating and stirring in all laboratory settings. The bright LCD display includes easy-to-read temperature and speed settings, intuitive icons and a prominent hot top indicator that lights up when the heater is above 40°C. Select from three plate sizes to suit your application. All models can be used with the optional temperature probe for precise temperature control of the sample.

The Guardian 3000 Series units offer safety, controlled heating, and powerful stirring for general laboratory use, all at a competitive price point. An industry-leading early detection system known as SafetyHeat uses two independent safety controls to monitor the electronics and stop heating before an overtemperature condition occurs. The rugged metal housing has a spill-resistant design for long life in the lab under harsh conditions. The smooth, chemical-resistant ceramic top makes for easy clean ups.
