Here’s the magnetic stirrer you’re looking for if you process high sample volumes in round bottomed or three-necked flasks.  The CAT KM16.7D hotplate stirrer is designed for processing 1,000 to 2,000 ml at precisely controlled temperatures to 450˚C.  Heat is transferred through a specially designed block to provide even distribution over the flask surface.  Both are positioned in a stainless steel container designed to catch and hold samples in case the flask breaks.

Stirring speeds from 60 to 1600 RPM along with all other operational parameters are set and monitored on an easy to read and intuitive control panel.  Features include an LED-equipped plate on/off button, a “View RPM” button, and a motor speed control.  Operational settings are established by push-button control to select plate temperature, probe temperature, safety temperature and timer. These are set by turning an encoder wheel to raise or lower values then pressing it to set them.  Once set and the unit is operating you can monitor these values on the 7-segment LED display by touching the respective buttons.

Status LEDs indicate when the hotplate is on; the heater is on, when the hotplate temperature exceeds 60˚C and when the timer is activated.

How simple is that?

As with most CAT magnetic stirrers the High Capacity KM16.7D is equipped to be controlled by a Pt100 temperature probe.  This enhances the safety features already built into the system itself.
