Hot Plate By Globetrek Engineering Corporation

Globetrek Engineering Corporation is a Manufacturer, supplier and exporter of Hot Plates. A hot plate is a portable self-contained tabletop small appliance that features one, two or more gas burners or electric heating elements. A hot plate can be used as a stand alone appliance, but is often used as a substitute for one of the burners from an oven range or the cook top of a stove. In laboratory settings, hot plates are generally used to heat glassware or its contents. Some hot plates also contain a magnetic stirrer, allowing the heated liquid to be stirred automatically. In a student laboratory hot plates are used because baths can be hazards if they spill, overheat or ignite, because they have a high thermal inertia (meaning they take a long time to cool down) and mantles can be very expensive and are designed for specific flask volumes.

Two alternative methods for heating glassware using a hotplate are available. One method is to suspend glassware slightly above the surface of the plate with no direct contact. This not only reduces the temperature of the glass, but it slows down the rate of heat exchange and encourages even heating. This works well for low boiling point operations or when a heat source's minimum temperature is high.
