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.
In order to categorically exclude accidents and fire, all models have two independent safety circuits that automatically switch off the hotplate in the event of an unwanted rise in temperature
A combination with Heat-On attachments makes the application even safer
All models are equipped with a visual residual heat indicator to prevent burns
For safety reasons, the device is switched off completely in the event of a short circuit, broken sensor of the temperature sensor, defective motor and in the event of a processor fault
A separate On / Off button for the heating function prevents unintentional heating. The activated heating function is clearly recognizable by the illumination of the button
To prevent any splashing, the rotation speed ramps up slowly until it has reached the desired value
Damage to the device is impossible even at the highest temperatures – all models are equipped with a fire-resistant die-cast housing
Even with the fastest heating times compared to conventional magnetic stirrers, the built-in PID controller guarantees precise control without overshooting the temperature
The unique Kera-Disk® coating is extremely resistant to chemicals and scratches. The hotplate is therefore easy to clean and dirt can be easily removed. A PID controller ensures precise control of the heating process
The powerful stirring magnet allows the stirring rod to be safely entrained even with larger quantities of up to 20 l
If the hotplate fails, the stirring process is not interrupted. This prevents the sample from overheating
Efficient cold insulation prevents condensation in the housing and thus contact between condensation water and electronic components – ideal for working with dry ice
On devices with a display, all parameters can be read from the large, illuminated display, even from a greater distance
With the free software support for the Hei-Connect model, processes can be reliably automated and documented – for up to four devices simultaneously
Clearly shorter process times. The high heating power of 800 Watt enables 35 % faster heating times compared to conventional magnetic stirrers with 600 Watt
Thanks to its aluminum core, the Kera-Disk® hotplate guarantees the fastest heating times. Due to the resistant ceramic coating, the plate is chemical-resistant and scratch-proof
Corrosion-protected electronics add many years to the operational lifespan and reduce expenditure for new purchases
Wear- and maintenance-free motors save repair and spare part costs
The average operational lifespan is on average more than 10 years, thus making your purchase a worthwhile investment
The sealed housing of the magnetic stirrers guarantees a long service life with low susceptibility to repairs
