Hotplate stirrer

The Arex hotplate stirrer from Velp Scientifica can be connected to a Vertex fuzzy logic thermoregulator to create a system for the direct control of the temperature of stirred liquids.

The stirring speed is microprocessor controlled, which ensures constant speed when stirring liquids where the viscosity is changing. A stirring acceleration ramp ensures a 'soft start'.

The high strength PCM composite magnet is powered by a brushless motor that is adjustable up to speeds of 1300 rpm and can handle volumes of up to 20 L.

The 155 mm diameter aluminium heating plate is coated with a chemical resistant coating. Together with the epoxy-coated body, it assures temperature uniformity across the plate and high chemical resistance. The hotplate is powered by a 750 W element and is thermostatically controlled up to 370°C.

When used in conjunction with the Vertex thermoregulator, the temperature can be controlled from ambient to 300°C with an accuracy of 0.5°C. Hemispheric bowl attachments are also available for round bottom vessels.
