Hanna Instrument Magnetic Mini-Stirrer (12VDC) – HI190M

The test sample should ideally be mixed before electrochemistry measurements are conducted. A magnetic stirrer is used to ensure correct mixing and uniform temperature and consistency of the sample. A sensor’s response time to obtain a stable reading is sped up by agitating the sample.

• Compact and economical

Due to its small size and light weight, the HI190M-0 mini-magnetic stirrer is simple to use in a laboratory setting. With the help of this sturdy, space-saving stirrer, a lack of space on laboratory benchtops is no longer an issue. Users at a distance are further assured that the stirrer is in use by power-indicating LED lights. Chemicals that are spilled accidently won’t destroy the sturdy plastic coating. For customers who do not require the additional costs of a heating element, the HI190M-0 magnetic mini-stirrer is a cost-effective option. The cutting-edge design includes electronic controls that let the user easily and precisely manage the speed.

• Speedsafe™

In the laboratory, a sample is frequently taken out of a stirrer before the speed has been sufficiently decreased. Normally, the internal motor would speed up until it was harmed. The SpeedsafeTM mechanism is incorporated into the HI190M-0 magnetic mini-stirrer to adjust speed in response to variations in viscosity or the removal of a load. With SpeedsafeTM, the stirring speed is tracked by an opto-sensor, which is connected to an FVC (frequency voltage converter). The voltage-controlled oscillator (VCO) is turned off by the speed limiter when the speed reaches a certain maximum level, which reduces the motor speed. This prevents the motor from rapidly accelerating to a high speed that would be dangerous to both the operator and the stirrer when the load is quickly withdrawn from the stirrer, a characteristic not frequently present in conventional stirrers.
