When performing pH and dissolved oxygen measurements, the sample being tested should be stirred. The use of a magnetic stirrer allows for proper mixing and the sample to be homogeneous in consistency and temperature. The stirring of the sample also helps speed up the response time of a sensor in achieving a stable reading.
Compact Design with Chemical Resistant Housing
· The MI0040 is less than 5.5” in diameter and 2” in height.
· The housing is made of ABS plastic and is resistant to common chemicals used in the lab.
To control the speed from changes in viscosity or removing of the load, the MI0040 magnetic stirrer incorporates an optical control mechanism. As the speed reaches a preset maximum level, the speed limiter shuts down the VCO (voltage-controlled oscillator) to slow down the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to such a high speed that will be hazardous to the stirrer; a feature not commonly found in conventional stirrers.
Speed Control
· The speed of the stirrer can be adjusted, using the dial on front, from 100 rpm to 1000 rpm.
· Stirrer has an optical feedback mechanism to adjust speed, whether from changes in viscosity or removal of the beaker/flask.
Visual Power Indicator and Fuse Protected
· An LED on the front of the stirrer signals that there is power to the stirrer.
· The stirrer is fuse protected with a replaceable 400 mA / 250V fuse.
