Stainless Steel Cover Magnetic Stirrer with AutoSpeed (5L) HI310N

Producer: HANNA Instruments

SKU: HANNA-HI310N Category: Hanna experimental measuring equipment

Stainless Steel Magnetic Stirrer with AutoSpeed (5L)

The HI310N is a compact and lightweight magnetic stirrer with an AISI 316 stainless steel cover. The stainless steel cover is ideal for stirring samples when performing exothermic reactions or solutions containing corrosive substances that would be damaged if the cover of a stirrer were made of plastic. Autospeed technology maintains constant speed as the torque load changes, ensuring that the sample is stirred evenly every time. The HI310N magnetic stirrer is an ideal space saver in the laboratory.

Custom speed

Ideally, when performing electrochemical measurements, the samples to be measured should be stirred. The use of a magnetic stirrer allows for proper mixing and the samples are homogenous in consistency and temperature. Sample agitation also speeds up the response time for a sensor to achieve stable measurement values.

Compact & Cost Effective

The HI310N magnetic stirrer is compact and lightweight, allowing for easy use in the laboratory environment. Limited space on the laboratory bench is no longer a concern with this durable, space-saving magnetic stirrer. Power-indicating LED lights help users to know at a distance when the stirrer is in operation. The durable plastic casing will resist the harmful effects of accidentally spilled chemicals. The advanced design incorporates electronic controls that allow the user to easily adjust the speed with great precision.

Stainless steel case

The HI310N stirrer is equipped with an AISI 316 stainless steel cover over an ABS body. This is an ideal cover for applications where exothermic reactions occur. AISI 316 steel is known to have high resistance to chloride corrosion.

Speedsafe™

Often in the laboratory a sample is removed from a stirrer before the speed has been reduced properly, causing the motor to accelerate further and this can cause damage to the internal motor. To control speed from changes in viscosity or when the load is reduced, the HI310N magnetic stirrer incorporates the Speedsafe™ mechanism. With Speedsafe, a speed sensing device (optical sensor) is combined with an FVC (frequency voltage converter) to monitor the stirring speed. When the speed reaches a preset maximum level, the speed limiter shuts down the VCO (voltage controlled oscillator) to slow the motor speed. This ensures that when the sample is suddenly removed from the stirrer, the motor will not accelerate and there will be no danger to the user or the stirrer; a feature not commonly found in conventional stirrers.

Protective fuse

For safety, in the event of a short circuit, the HI310N is equipped with a replaceable fuse. The circuitry of the HI310N will be further protected.

Autospeed

For non-Newtonian fluids such as oils and clays, the viscosity changes during stirring, making it necessary to adjust the power to maintain a constant speed during stirring. Hanna Auto-Speed agitators are designed with automatic feedback control to maintain a constant speed as the torque load changes and are therefore ideal for stirring non-Newtonian fluids where the viscosity changes during stirring. They are also ideal for mixing applications where one solution is added to another which changes the power and therefore the torque load on the agitator. The Auto-Speed agitators maintain a constant stirring speed during mixing up to a capacity of 5 litres. They can also be used with Newtonian fluids up to a capacity of 5 litres.
