Model HP1818 hot plate, shown here, is protected with a heavy, ceramic- filled glass plate, which is resistant to most acids.  The interior of the plate is sealed from corrosive fumes and leakage, and all fittings are Teflon coated. A corrosion-resistant flexible conduit connects the hot plate to the remote digital thermostat. The plate is easily removed for cleaning.   For maximum air flow, Wenesco's hot plate meets the 2-inch clearance requirement under the plate.

This photo, taken at our customer's facility, shows Model HP1218CR corrosion-resistant hot plate heating various acids under a fume hood. Wenesco's remote temperature controller is not visible, because it is safely out of the harshly corrosive environment.

Independent test on materials used on our corrosion-resistant hot plate "200 ml of TCu digestion acid ( Nitric 65.1 to 66.5% + Hydrofluoric 0.5 to 1.5% + Potassium Chlorate 3 to 5% + H2O 27 to 31.4% ) were put into a 400-ml Teflon beaker. The coated samples were placed in the acid. This ended up having to be gradual because the mere introduction of the test pieces to the acid at room temperature started a rather vigorous bubbling action. After the bubbling subsided, the beaker was covered and brought to a boil. The flasks were removed from the heat and left for 48 hours.   "The materials tested suffered no appreciable deterioration."
