Globe Scientific Stirrer, Analog, 7 x 7 inch glass ceramictop plate, 100-120v, 50-60Hz

The GHS-550 group of Hotplates, Magnetic Stirrers and Magnetic Stirrer Hotplates offer safety and precision for laboratory heating and mixing applications. The compact and low-profile design saves valuable benchtop space and a 7-inch chemical resistant glass ceramic working surface ensure years of service and easy cleanup.

Setting the heat and stirring speed is extremely intuitive with an LED display and control knobs, inputting to a microprocessor-controlled circuit for accurate, stable control of heating and stirring.  

The GHS-550HSP model replaces the LED with an LCD display for precise monitoring of speed and temperature.  This hot plate magnetic stirrer also includes a built-in PID temperature control heating with overheating protection. A RS232 port offers remote function for communication, PC control and data transmission (software not included).

The Magnetic Stirrer and Hotplate Magnetic Stirrer are designed to provide a strong magnetic coupling for powerful mixing that is enabled by the maintenance free brushless DC motor.  The stirrers can mix up to 10 liters of water (GHS-550HS, GHS-550S) or 20 liters of water (GHS-550HSP), which allows for excellent homogeneity of your solution. 

The Hotplate and Hotplate Magnetic Stirrer models are designed with a powerful 1000-watt heater that provides temperatures up to 550°C.  To gain even more accurate temperature control within 0.2°C, an optional PT1000 sensor and retort stand are available to measure directly in the vessel.  A “hot” warning will flash if the work plate temperature is above 50°C. Overtemperature protection is included should temperatures reach 580°C.
