Product Overview

• HI190M-0 is a compact and lightweight magnetic stirrer with an operating voltage of 12VDC (sold separately). The HI710005 12VDC adapter is an essential accessory for powering the mini stirrer. This mini stirrer features an ABS plastic housing and cover that resist many harmful chemicals for long-lasting durability. Stirring speed is adjustable between 100 and 1000 RPM. The HI190M-0 stirrer requires very little space, which is invaluable when laboratory benchtop space is at a premium.

• Speedsafe™ mechanism

• Power indicator light

• Adjustable speed control

• Ideally, the sample being measured should be stirred during electrochemical measurements. Proper mixing can be achieved using a magnetic stirrer, making the sample uniform in consistency and temperature. Stirring the sample also helps accelerate the sensor's response time to achieve stable readings.

• Compact and cost-effective

• The HI190M-0 mini magnetic stirrer is compact and lightweight, making it easy to handle in laboratory environments. This durable, space-saving stirrer eliminates concerns about limited benchtop space. The power indicator LED also reassures users from a distance that the stirrer is running. The durable plastic cover resists the harmful effects of accidental chemical spills. The HI190M-0 magnetic mini stirrer is cost-effective for customers who do not need the extra expense of a heating element. The advanced design incorporates electronic control, enabling users to easily and precisely adjust the speed.

• Speedsafe™

• Typically in the laboratory, the sample is removed from the stirrer before the speed is sufficiently reduced. This usually causes the internal motor to accelerate until it is damaged. To control speed changes due to viscosity changes or load removal, the HI190M-0 magnetic mini stirrer employs the Speedsafe™ mechanism. With Speedsafe™, a speed sensing device (optical sensor) is coupled with an FVC (frequency-voltage converter) to monitor stirring speed. When the speed reaches a preset maximum level, the speed limiter shuts off the VCO (voltage-controlled oscillator) to reduce motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to high speeds that are harmful to both the user and the stirrer; this is a feature not commonly found in conventional stirrers.
