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.
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
