Details

Ideally when performing electrochemistry measurements, the sample being tested should be stirred. The use of a magnetic stirrer allows for proper mixing, ensuring that the sample is homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time for a sensor to achieve a stable reading.

Compact & Cost-Effective

The HI324N magnetic stirrer is compact and lightweight, allowing for easy handling in the laboratory environment. Limited area on laboratory benchtops is no longer a concern with this durable, space-saving stirrer. Power-indicating LED lights also assure users at a distance that the stirrer is in operation. The durable plastic covering will resist harmful effects of accidentally spilled chemicals. The HI324N magnetic mini-stirrer is cost-effective for the customer that does not need the added expense of a heating element. The advanced design incorporates electronic controls that allow the user to easily regulate the speed with great precision.

Timer-controlled

HI324N stirrer is equipped with timer control to start and automatically stop the stirring process after an user-selectable period (from 5 minutes to 2 hours). They are the ideal stirrers for routine applications where the required stirring time is known, and for non-Newtonian fluids whose viscosities change during stirring or Newtonian fluids up to 5 liters capacity.

Built-in Tachometer

HI324N stirrer has a built-in 4-digit LCD tachometer that shows the stirring speed in RPM for ultimate accuracy.

Stainless Steel Cover

HI324N stirrer comes supplied with an AISI 316 stainless steel cover atop the ABS body. The cover is an ideal solution for applications in which exothermic reactions occur. The AISI 316 type of steel is known to have increased resistance to chloride corrosion as well.

Speedsafe

Often in the lab a sample is removed from a stirrer before the speed is adequately reduced. Normally this would cause the internal motor to accelerate until it is damaged. To control the speed from changes in viscosity or removing of the load the HI324N magnetic mini-stirrer incorporates the Speedsafe mechanism. With Speedsafe, a speed sensing device (opto-sensor) is coupled with an FVC (frequency voltage converter) to monitor the stirring speed. 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 both the user and the stirrer; a feature not commonly found in conventional stirrers.

Fuse Protection

For safety, in the event of a short circuit, the HI324N is equipped with a replaceable fuse. The circuitry of the HI324N is grounded to the case for additional protection
