1. Introduction
The AREC 7 Connect heating magnetic stirrer with ceramic plate is used to heat and mix liquids inside a suitable container
placed on the ceramic 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 a precise regulation of the
stirring speed and of the heating plate temperature.
The ceramic heating plate allows to reach higher temperature than a traditional aluminium heating plate; furthermore, the
ceramic is an inert and very hard material, so it offers great resistance to almost any type of chemical or mechanical
aggression keeping the surface characteristics unaltered over time.
The heating plate works up to 550 °C.
The powerful brushless motor is able to stir from 30 up to 1700 rpm.
SpeedServo technology maintains constant speed as viscosity changes.
The instrument is equipped with advanced functions as auto-reverse of the stirring direction, intermittent mode programs
and integrated timer to meet users' workflow and safety lock feature to avoid possible alteration of the working conditions.
The AREC 7 Connect can work in combination with the Pt100 external probe for precise and accurate control of the sample
temperature.
The integrated Wi-Fi module transmits and receives information in order to monitor and control the unit through the VELP
Ermes cloud platform.
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).
