iStir HP 320 Digital Hotplate Stirrer

The iStir HP 320 is a digitally controlled hotplate magnetic stirrer designed for accurate, repeatable heating and mixing in research, clinical, educational and industrial laboratories.

It combines a maximum stirring capacity of 10 litres with a temperature range extending to 320°C. Stirring speed can be set from 200 to 2,200 RPM in precise 10 RPM increments, making the instrument suitable for both gentle solution preparation and rapid mixing.

A PT1000 temperature probe is supplied for monitoring the temperature of the sample directly. The large digital display, programmable timer and last-run memory provide the control required for repeatable laboratory procedures.

The iStir HP 320 is available with a choice of three top-plate materials. One plate should be selected when ordering:

The supplied PT1000 probe measures the temperature inside the vessel rather than relying solely on the temperature of the hotplate. This provides a more meaningful indication of the sample temperature during heating and mixing.

A support stand and boss-head clamp are included to hold the probe securely inside the vessel throughout the procedure.
