The HS40 series programmable hot plate stirrers from Torrey Pines Scientific is ideal for precise heating and mixing of your samples. Mounted into a cast aluminum frame, the chemically resistant ceramic heater top of the HS40 is best for heating liquid media in a vessel.

When heating solids directly on the plate surface, the HS40A 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 provide a 203 x 203 mm heater top with a heater power of 600 W. A platinum RTD sensor located under the plate surface determines the current temperature and forwards the information to a PID control loop. Up to 2 liters of aqueous solution can be mixed over a speed range of 100 to 1,500 rpm.

The HS40 series magnetic stirrers is fully programmable. Its memory holds 10 methods, consisting of a maximum of 10 steps. Each step may contain a temperature, heating rate, mixing speed and timed event. Every method can be repeated up to 98 times or run continuously.

A DIN jack on the rear side of the unit accommodates an optional immersion probe, used to determine solution temperatures. In this regard we strongly recommend the use of a immersion probe for the most accurate temperature control.

The HS40 series hot plate stirrers comes with a large, easy-to-read LCD. The following parameters are displayed: measured plate surface or solution temperature (by means of immersion probe), mixing speed, count-down timer in hours, minutes and seconds, temperature ramp value as well as program steps.

All models feature a factory set electronic calibration, traceable to NIST, however, the user is able to recalibrate the unit to his own standard. A RS232 I/O port enables data collection or external PC control of the unit.
