 Price List     PDF price list - Torrey Pines Scientific Laboratory Equipment
The Torrey Pines Scientific HS50 series digital hot plate stirrers is designed specifically for smaller samples and therfore comes with compact dimensions. Mounted into a cast aluminum frame, the chemically resistant ceramic heater top of the HS50 is ideally suited for precise temperature control of liquid media.

When heating solids directly on the plate surface, the HS50A 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 152 x 152 mm heater top with a heater power of 400 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.

A DIN jack on the rear side of the unit accommodates the 102 mm long stainless steel immersion probe which is included with each unit and used to determine solution temperatures. In this regard we strongly recommend the use of a immersion probe for the most accurate temperature control.

The HS50 series stirring hot plates 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, as well as count-down timer in hours, minutes and seconds. Two memory buttons store the user's favorite settings for instant, one-button recall and use.

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.
