1. Introduction
The AREX 5 Digital heating magnetic stirrer is used to heat and mix liquids inside a suitable container placed on the
aluminium plate. The stirring is possible thanks to a magnetic drive stir bar placed into the vessel.
The instrument is used in the laboratory for general use and for all those applications that require precise regulation of the
stirring speed and of the heating plate temperature.

The Aluminium alloy heating plate with ceramic coating (1) ensures:
•
Optimum heat distribution and a high specific power thanks to the circular configuration
•
Temperature homogeneity
•
High resistance to thermal stress and thermal shock
•
High resistance to chemical agents and surface abrasion
Note: Using the heating plate at high temperatures may cause discolouring. This does not alter the thermal, mechanical and
chemical resistance of the plate in any way.
The powerful brushless motor is able to stir from 50 up to 1500 rpm.
SpeedServo technology maintains constant speed as viscosity changes.
Note: it's important to choose the most suitable magnetic stirring bar related to the type and the quantity of the liquid to be
stirred as well as to the type of the beaker. Size and shape of the magnetic stir bar determines the stirring efficiency at any
given speed. The stirring bar which satisfies most applications is code A00000356 (8 x 40 mm).
The AREX 5 Digital can work in combination with the Pt100 or Pt1000 external probe or with thermoregulator VTF for
precise and accurate control of the sample temperature.
