Hot Plate Stirrer, Programmable, Model HS61/HS61A from Torrey Pines Scientific

 Price List PDF price list - Torrey Pines Scientific Laboratory Equipment
The Torrey Pines Scientific HS61 series programmable hot plate stirrers is designed specifically for larger samples. Mounted into a cast aluminum frame, the chemically resistant ceramic heater top of the HS61 is ideally suited for precise temperature control of liquid media.

When heating larger sized solids directly on the plate surface, the HS61A 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 305 x 305 mm heater top with a heater power of 1,400 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 5 liters of aqueous solution can be mixed over a speed range of 100 to 1,500 rpm.

The HS61 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 the 254 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 HS61 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.
