Product Description:

Each Torrey Pines Scientific hot plate is made with a cast aluminum chassis that is painted with chemically resistant epoxy paint. The chassis is designed to keep spills out of the case. Corrosion resistant models have most air holes closed off and have purge ports for putting a positive pressure of any inert lab gas into the unit. Positive pressure inside the chassis keeps the corrosive gasses out. This extends the life of the “C” version units when working with aggressive chemicals.

Heating and stirring controls are solid state with individual indicator lights, which illuminate when either is activated. The controls are well forward of the heater surface to prevent accidental burns. Additionally, the solid ceramic heater plate is framed in cast aluminum and is designed to keep heat from the edge of the heater plate.
