Hot Plate Stirrer, Analog, Model HS1/HS1A from Torrey Pines Scientific

 Price List PDF price list - Torrey Pines Scientific Laboratory Equipment
The compact HS1 series analog hot plate stirrers from Torrey Pines Scientific requires minimal bench space for quick and easy heating and mixing of your samples. Mounted into a cast aluminum frame, the chemically resistant ceramic heater top of the HS1 is best for heating liquid media in a vessel.

When heating larger sized solids directly on the plate surface, the HS1A is the instrument of choice. Its heater top is made from a cast aluminum alloy, enabling minimum pitting when milled. It is very flat and, thanks to its better heat conductivity, provides a more uniform heating across the surface, compared to ceramic glass.

Both models are driven by an open loop control and provide a 152 x 152 mm heater top with a heater power of 400 W. Up to 2 liters of aqueous solution can be mixed over a speed range of 100 to 1,500 rpm.

The handling of the HS1 series stirring hot plates is very easy. Stirring speed and temperature are set with the corresponding stepless control knobs which are placed well forward of the heater surface to prevent accidental burns. A control light indicates that the heating function is in operation.
