Magnetic hotplate stirrers, AREX Digital and AREX Digital PRO
Imánes de agitación Agitadores magnéticos con placas calefactoras
Magnetic hotplate stirrers with ceramic coated aluminium alloy top plate that provides even heat distribution and excellent chemical resistance, together with easy cleaning and scratch protection. These units are suitable for continuous operation, offer precise temperature control and plate stability, and feature an elevated front panel with run-off groove, which protects against spills and leaks. The control panel is separated from the hotplate ensuring increased safety and durability. Easy to operate, temperature and speed are controlled via two knobs. Hot warning light will show whenever the plate temperature is above 50 °C.

  • Maximum safety temperature limit can be set between 50 and 370 °C
  • Digital display shows set stirring speed plus set and actual temperature
  • Models maintain constant speed even when the sample viscosity changes
  • Both units support AluBlocks™ or hemispheric bowls up to 1 L, enabling different heating and stirring experiments to be carried out, with the hotplate stirrer becoming a personalised workstation

AREX Digital PRO is one of the most advanced hotplate stirrers. By turning the left knob it is possible to adjust the temperature (up to 370 °C), whilst the right one controls the stirring speed (up to 1500 rpm). SpeedServo™ ensures constant speed even when the viscosity changes (counter-reaction).

The AREX Digital PRO hotplate stirrer ensures a high level of safety and protection for the user. The control panel is easily accessible, positioned at a safe distance from heat sources and is protected against possible damage caused by liquid spills thanks to a dedicated run-off groove.

AREX Digital PRO can be programmed with a maximum safety temperature, useful for some applications to avoid exceeding certain temperatures, and preventing unintentional heat up. In addition, a high temperature warning 'Hot Plate Warning' is activated and displayed even when the instrument is turned off, until the plate temperature has cooled to below 50 °C. The pressure die-cast structure is designed so that accidental liquid spills cannot reach the internal parts of the hot plate stirrer.

The AREX Digital PRO has a low profile design for an outstanding comfort. The front panel is inclined, this facilitates use and allows the user to easily read digital displays. The CerAlTop™ , made of aluminium alloy covered with ceramic, ensures excellent temperature homogeneity and optimum heat transfer across the entire surface, of up to 370 °C. The special protective white ceramic coating that ensures ease of cleaning and excellent resistance to chemicals, scratches and surface abrasions.

Información accesorios: VELP Hemispheric bowls are an ideal replacement for oil baths and mantles ensuring clean and safe analysis with round bottom flasks. Hemispheric bowls fit the Ø 135 mm plate and the flask surface precisely, ensuring fast heat transfer.

Información de suministro: AREX Digital PRO is supplied as a choice of packages, including either a PT100 external probe, for thermoregulation up to 250 °C, with an accuracy of ± 1.0 °C and allowing direct thermoregulation and control of the liquid. Alternatively a VTF Digital Thermoregulator, for precise thermoregulation up to 300 °C, with accuracy of ± 0.5 °C which allows unsupervised operation thanks to the integral timer.
