 Price List PDF price list - Torrey Pines Scientific Laboratory Equipment
The Torrey Pines Scientific HS70 is a compact, programmable magnetic stirrer with heater designed specifically for corrosive environments. The HS70 comes with a 1/4"-18 NPT connection and can be purged using a dry inert gas. The purging process leads to a positive gas pressure within the unit, preventing corrosive gases from entering. This can extend the unit's life in many demanding laboratory environments significantly.

The 203 x 203 mm chemically resistant ceramic heater top of the HS70 is mounted into a cast aluminum frame and is ideally suited for precise temperature control of liquid samples with a heater power of 600 watts. 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 HS70 hot plate stirrer 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 153 mm long PTFE 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 HS70 magnetic stirrer with heater 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.
