Category Hot Plate Stirrers
Manufacturer VELP Scientifica
Country of manufacture Italy

The AREX has an aluminum alloy heating plate to ensure uniform heat distribution over the entire surface, with a special protective white ceramic coating that ensures easiness of cleaning and excellent resistance to chemicals, scratches and surface abrasions. This hot plate stirrer ensures precise thermoregulation of the heating plate as well as a high degree of reliability and safety. The AREX is designed to last and equipped to ensure  maximum protection against leakages with the elevated front panel and dedicated run-off grove. 

The control panel is separated from the hot plate, this feature increases the safety rating during use and the durability of the instrument.

The inclination of the front panel has been carefully studied to facilitate use.

The AREX has a socket for the connection of a VTF/VTF EVO Vertex digital thermoregulators for direct temperature control of the liquid.
