Superior safety and durability

Superior safety and durability

The AREX-6 Connect PRO is provided of 2 independent safety circuits that switch-off the heat preventing possible hazard in all cases of overtemperature (higher than the set point).  

When the plate temperature is 50°C  the display will show a residual hot plate message preventing potential burning.


The probe detection alarm of the AREX-6 Connect PRO detects that the external probe is not immersed in the medium and stops the heat preserving the sample from burning.

With the AREX-6 Connect PRO is now possible to adjust the maximum operating temperature in order to meet all the Labs safety standards.

The AREX-6 Connect PRO is IP42 certified and thanks to the resistant die-cast housing and the run-off grove all the internal parts of the instrument are protected from potential damages.

The AREX-6 Connect PRO is designed for the longest lifespan and guaranteed by 3 years warranty (register online your AREX-6 Connect PRO to get the warranty extension).


State-of-the-art thermoregulation

State-of-the-art thermoregulation

Best in class thermoregulation extremely stable, fast and with minimal overshoot thanks to the PID thermoregulation software.

The AREX-6 Connect PRO includes Pt100 Probe and can be connected to VTF for precise and accurate control of the temperature of the medium.

Working with the Pt100 probe It is possible to choose 2 different thermoregulation modes to match all requirements:

  • FAST: the Hot Plate Stirrer quickly reaches to the set point temperature with a little overshoot
  • FINE: slower temperature set point reaching with an optimized overshoot


Easy to use and smart user interface

Easy to use and smart user interface

The bright white LED display with black background is easy to read and thanks to the icons the operator has always the clear readout of the working conditions.

The icons inform about: probe connection, heat activation, set point temperature, timer activation and auto-reverse option. 

Lock your instrument by pressing the central button for 3 seconds, a white LED will blink if an interaction is detected. 


Two extremely precise turning knobs control the temperature and speed setting and for starting the heating is now necessary to tap the knob for complete safety.

By tapping at the same time both knobs it is possible to access to the advanced menu for the most suitable configuration of all operating modes.


Superior performances

Superior performances

The powerful brushless motor is able to stir from 30 up to 1700 rpm. Speed is always constant as viscosity changes with the torque compensation SpeedServo.

The strong Alnico Magnet provides state-of-the-art magnetic coupling and guarantees excellent peripheral stirring very important when combining the AREX-6 Connect PRO with the accessories.

The 135 mm diameter top is protected from chemicals and scratches by the resistant CeAlTop™ ceramic coating. It is made of aluminum alloy that guarantees temperature homogeneity and the fastest heat transfer and of a thin layer of ceramic protecting the plate.


Program your reactions with timer and auto-reverse option

Program your reactions with timer and auto-reverse option

The central button permits to set the timer in order to save time to the operator and enabling unsupervised work.

The timer is settable from 1 min up to 99 hours and in the advanced menu is possible to configure it as follow:

  • Snap: timer countdown starts as soon as one main function (Temperature/Speed) is on
  • SetP: timer countdown starts when temperature set point is reached

The Auto-reverse option enhances the kinetics by changing the direction of the stirring direction. Is also possible to set the change in direction at the preferred interval of time.
