Advanced microprocessor controls with convenient turn knobs allow quick, precise adjustment and maintenance of speed and temperature. The safety indicator LED on the front panel indicates when stirring and/or heating functions have been activated. The 7.5" square work surface is compatible with popular sizes of borosilicate glass beakers, flasks, bottles and other vessels. Comes complete with a support rod for mounting thermometers and temperature probes.

The Economical Small, 6 x 6� (15.2 x 15.2cm), model is perfect for the budget conscious classroom, clinic or lab. The Medium, 12 x 12" (31 x 31cm), or Large, 12 x 24" (31 x 61cm), top plate surfaces accommodate up to 40 lb (18kg) loads, and all three models have stainless steel cases which provide optimum strength for heavy loads.

The temperature range is 100�F to 700�F (38�C to 371�C). Aluminum top plates outperform other materials, providing superior temperature uniformity and stability. At 212�F (100�C), theSmall model offers � 4.3�F (� 2.4C) uniformity and � 5.4�F (� 3.0�C) stability, theMedium model offers � 7.2�F (� 4.0�C) uniformity and � 5.4�F (� 3.0�C) stability, and theLarge model � 18�F (� 10.0�C) uniformity and � 6.3�F (� 3.5�C) stability. Due to the high wattage draw, the Large unit is not supplied with cord nor plug, and must be connected through electrical conduit fittings. The Small and Medium units are supplied with cord and plug. All units are 120V. Recommended for use with glass vessels only.

The GHS-550H Hotplates provide a safe and precise solution for laboratory heating needs. With its compact and low-profile design, it saves valuable space on your benchtop. The 7-inch working surface is made of chemical-resistant glass ceramic, ensuring durability and easy cleaning. Controlling the heat is simple and intuitive, thanks to the LED display and control knobs, which are connected to a microprocessor-controlled circuit for accurate and stable control. The speed can be easily adjusted using the analog knob and scale.
