Need short- or long-term stirring when your samples are in round-bottom flasks?  The answer is the precision CAT KM16.4D magnetic stirrer equipped with a special heating block and flask container created just for that purpose.  Use it when stirring quantities from 100 to 500 ml and at temperatures to 450˚C. Of stainless steel construction the container is designed to hold samples in event the flask cracks and starts to leak.

The KM16.4D magnetic stirrer control panel is a study in simplicity.  One read through the comprehensive instruction manual and you can quickly set operating parameters all shown on the 7-digit liquid crystal display.  Simply by touching the control buttons you are in charge of plate temperature, stirring RPM, Pt100 probe temperature, stirring time (1 to 999 minutes) and time remaining.    Use the motor speed wheel for minimum to maximum (60 to 1600) RPM stirring action.  The unit is equipped with soft start to avoid splashing content out of the flask.

Safety features, enhanced with the optional Pt100 temperature probe, guard against overheating, accidental loss or spillage of sample, software breakdowns and similar events by initiating a controlled shutdown of the unit.

Check our further details on the CAT KM16.4D magnetic stirrer for round bottom or three-necked flasks and contact us if you have questions.
