Wenesco Corrosion-Resistant Hot Plates
Wenesco corrosion-resistant hot plates are not affected by the boiling acid fumes and splashes that will eventually destroy conventional hotplates. The housing and plate are treated with a proprietary coating material and is sealed to prevent fumes entering the interior.

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."

All models feature operating temperatures up to 325C with good uniformity across the plate surface. Wenesco hot plates meet the 2-inch clearance requirement under the housing for maximum air flow.
