Features

Thermoplate™ Features

MHI Thermoplates™ are an industrial grade, high power, high temperature hot plate capable of reaching temperatures of 1250°C within 4 seconds after initially reaching full power. Ideal for use as a laboratory hot plate. Thermoplates™ feature a stainless steel construction and electronic controls. Thermoplates™ are offered with quartz or ceramic tops, both exhibiting excellent uniformity.

General Information
Radiative Power: High power relative to other hot plates available (3 kW for Thermoplate). Temperature: Up to 1250°C depending on model. Construction: Stainless steel construction. See pictures below for display of complex ceramics mated for high temperature and thermal expansion considerations. 4 Second heat-up rate after reaching full power. Sleek Quartz or Radiative Ceramic top for easy cleaning and rapid heat up. Spiral elements give extremely uniform temperature distribution. Special high uniformity RTP heaters are also available. For fastest heat up please review e-Ion Zapper. Independently locatable control electronics shown below. Internal features of the thermoplate construction include combinations of special ceramics and metals with the UltraSpiral heating element as shown in pictures below.

HeatPad™ Microheater

HeatPad™ Microheater

HeatPad™ Microheaters are classified as semi-finished modules, which needs to be installed only by certified electricians who are congnizant of the dangers that come from exposed electrical and thermal systems. Please do not hesitate to have your electrician contact MHI.

HeatPad™ Microheaters are a small scale spot heater. The HeatPad™ is often used as a localized or substrate heater due to the small size. Using around 100 watts, the HeatPad™ is highly efficient. HeatPads™ feature integrated thermocouples.

Customer Feedback

Hot plate:
“...experience was that the hot plate center would get to temperature first then over time the edges would come up to temperature and be uniform. I believe once steady state was reached the uniformity was +/- 2 or 3C."

Please call MHI on details and full explanation. The uniformity depends on the thermal environment and other factors.
