VELP Heating magnetic stirrers AREC

 

The AREC is a digital heating magnetic stirrer with a white ceramic heating plate extremely resistant to corrosion and easy to clean. It is suitable for observing colour changes (e.g. during titration, etc.). The control panel is separated from the heating plate, this feature increases the safety rating during use and the durability of the instrument. The inclination of the knobs has been carefully studied to facilitate use. A microprocessor ensures constant speed even when the viscosity changes (counter-reaction). The AREC has an ergonomic and innovative design with a clear and bright digital display.
The  electronic control board activates a high temperature warning that remains displayed while the instrument is in use at temperatures of above 50 °C. When the instrument is turned off the high-temperature warning flashes until the temperature of the plate has cooled to below 50 °C. Metal vessels can be used.

Electronic speed regulation: up to 1300 rpm

Stirring volume (H2O): up to 15 lt.

Temperature: up to 540 °C

Counter-reaction: constant speed even when the viscosity changes
