Hanna Instruments HI 301N Two-Speed Magnetic Stirrer With Speedsafe Reviews
Hanna Instruments HI 301N Two-Speed Magnetic Stirrer With Speedsafe Feature
- Heavy-duty for long life usage
- Dual motors for dual range precision
- Can stir up to 2.5 liters (0.66 gallons) of liquid
- The motor is electronically controlled to maintain the chosen speed as the load changes
Similar to the "ZOOM" function of a microscope, these stirrers allow access to two separate stirring ranges. In each range, the speed can be fine tuned for exacting accuracy. This assures maximum repeatability in experiments and processing for laboratory, as well as production use.
In addition to speed control, a limiter will assure that the maximum speed will never be exceeded (Speedsafe). Often, in the lab, a sample is removed from the stirrer before reducing the speed. This would normally cause the motor to accelerate until it is destroyed. HANNA® stirrers incorporate a VCO device that will stop the motor from accelerating as soon as the load is removed.
