When choosing a hot plate for your laboratory, the top plate material is a primary determining factor in meeting the needs of your application.

Two top plate material options are:

  • Aluminum surfaces produce the best temperature uniformity but have poor chemical resistance.
  • Ceramic surfaces are the most chemically resistant but have poor temperature uniformity. However, ceramic-coated surfaces on a laboratory hot plate provide the best balance of temperature uniformity and corrosion resistance in hot plate construction.

Depending on how you plan to use your hot plate, your decision of which top plate material to choose may be easy. Keep in mind other criteria, such as temperature range, plate size, and weight capacity before making your final choice.
