Magnetic Stirrers

Hei-Mix L

P/N: 036110465

Stirring up to 20 liters without heating

Based on our proven magnetic stirrer series with heating function, the Hei-Mix L was especially developed for applications with thermolabile substances. This is because this model has no heating, and the heat from the motor is also not transferred to the footprint.

The Hei-Mix L magnetic stirrer without heating function is ideal for applications up to 20 liters and can gently stir your solution in a speed range of 100-1.400 rpm. In addition, the rotation speed ramps up slowly until it has reached the desired value. This prevents splashes, uneven starts, or jumps of the stirring rod.

The patented Kera-Disk® footprint made of aluminum with a ceramic coating, is chemical-resistant, scratch-proof, and has a diameter of 145 mm. This unique size makes it suitable for use with many accessories and samples on a small footprint.

 

Hei-Mix L - Product Advantages

To prevent accidents or laboratory fires, all magnetic stirrers feature two independent safety circuits which switch off heating in case of any overtemperature situation

In combination with Heat-On attachments you can convert your lab into a “safety zone"

A residual heat indicator for all models prevents you from potential burning hazards

For your safety, the unit will power off in case of a short-circuit, a damage to the temperature sensor, a motor failure or other incidences during operation

A separate on/off switch for heating prevents unintentional heat-up. If heating is switched on, the on/off button is illuminated for visual control

To protect you from splashes and scalding from bath media, rotation speed ramps up slowly until unit has reached the pre-programmed speed

Even if the stirrer is exposed to the highest temperatures, damage is categorically ruled out – all models come with a fire-resistant die-cast housing

You can even work with dry ice – a robust thermal insulation prevents corrosion inside the housing by preventing condensate from collecting and dripping on any electronic components

The unique Kera-Disk® coating is extremely chemical-resistant and scratch-proof, and therefore the plate can be cleaned easily from solvents, oil or other contaminations

The strong magnetic field allows for easy stirring of even higher viscosity media

In case the heating function fails, stirring will not be discontinued to avoid thermal damage to your sample

The hermetically-sealed housing protects all mechanical and electronic components from aggressive environments

The maintenance-free non-sparking motors reduce down times

The design and features give an increased lifespan of 10 years along with significantly reduced maintenance and repair costs
