Product Overview

• HI180 is a lightweight, low-cost magnetic mini-stirrer. The stirrer is compact, easy to operate, and requires very little space. The HI180 mini-stirrer is available in 11 colors for easy identification on a crowded benchtop.

• Lightweight design

• Speedsafe™ mechanism

• Adjustable speed control

• Ideally, the sample to be measured should be stirred during electrochemical measurements. Proper mixing can be achieved with a magnetic stirrer, and the sample will be uniform in consistency and temperature. Stirring the sample also helps speed up the sensor response time for stable readings.

• Compact, colorful, and cost-effective

• The HI180 series micro magnetic stirrers are compact and lightweight, making them easy to handle in laboratory environments. These colorful, space-saving stirrers no longer focus attention on the limited area of the laboratory benchtop. Several HI180 mini-stirrers can be placed on the laboratory workbench at the same time, and the ten available colors help users identify different samples. The power indicator LED also reassures users from a distance that the stirrer is running. The durable plastic cover will resist the harmful effects of accidental chemical spills. The HI180 magnetic stirrer is cost-effective for customers and does not require the added expense of a heating element. It combines electronic control so that users can easily adjust the speed more precisely.

• Speedsafe™

• Typically in the laboratory, the sample is removed from the stirrer before the speed is sufficiently reduced. Usually, this causes the internal motor to accelerate until it is damaged. To control speed through viscosity changes or load removal, the HI180 magnetic mini-stirrer incorporates the Speedsafe™ mechanism. With Speedsafe™, a speed sensing device (photoelectric sensor) is connected to an FVC (frequency-to-voltage converter) to monitor the stirring speed. When the speed reaches a preset maximum level, the speed limiter turns off the VCO (voltage-controlled oscillator) to reduce the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to a high speed that is harmful to both the user and the stirrer; this is not common in conventional stirrers.
