Safe and compact digital multi-position magnetic hotplate stirrers available with 6 or 15 positions. The MULTI-HS include features such as timer, safety lock, the brushless motor provides maximum performance and safety.

• Synchronous stirring and heating of 6 and 15 positions
• Homogeneous temperature up to 120 °C for all positions
• CerAlTop™ plate ensures easy cleaning and maximum resistance
• Brushless motor ensures longevity and guarantees constant speed at all positions
• SpeedServo™ technology maintains constant speed even when viscosity changes
• Programmable auto-reverse of the stirring direction
• Safe hot plate warnings when the plate temperature is above 50 °C

The MULTI-HS hot plate stirrers have a unique system of warnings: When the plate temperature reaches 50 °C the display will show a residual hot plate message preventing accidental burning. The safety lock feature avoids potential alteration to the working conditions or unintentional modification of the settings in order to meet all the laboratories safety standards.

The CerAlTop™top plate is made of aluminium alloy that guarantees temperature homogeneity with optimum heat distribution and a high specific power thanks to the circular configuration. A thin ceramic layer protects the plate from scratches and chemicals, ensuring high resistance to thermal stress and thermal shocks. The LED display is easy to read and thanks to intuitive icons the user always has a clear readout of the working conditions: Heat activation, set point temperature, timer activation, auto-reverse option and lock button.

Two extremely precise turning knobs control the temperature and speed setting, to safely start the heating simply tap the heating knob. By tapping both knobs at the same time it is possible to access to the advanced menu for the most suitable configuration of all operating modes. The extremely powerful brushless motors are able to stir from 100 up to 1000 rpm offering a virtually unlimited duration. Size and shape of the magnetic stir bar determines the stirring efficiency at any given speed and it is always constant as viscosity changes with the torque compensation SpeedServo™. The central button allows the timer to be set to save the user time and enable unsupervised work.

The Timer can be set from 1 min up to 99 hours and 59 minutes and in the advanced menu is possible to configure it as follows: 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 a preferred interval of time.

Autoreverse: 5 s to 99 min 59 s
