The system includes: pt100 probe (code A00000268), rod (code A00001069) and clamp (code A00000280);  (more)magnetic stir bar Ø8x40 mm (code A00000356). Magnetic stirrer AREC.X 7 Precise and accurate thermoregulation for better reproducibility AREC.X 7 is equipped with state-of-the-art heating plate technology, designed by VELP, which guarantees temperature homogeneity, thermal efficiency and long-lasting heating performance. The AREC.X 7 can be connected to the external Pt100 probe or to the VTF for precise thermoregulation of the fluid. The probe guarantees thermoregulation up to 250°C, with an accuracy of ± 1.0°C, while the VTF guarantees excellent thermoregulation performance up to 300°C and an accuracy of ± 0.5°C. The VTF is equipped with a timer, for unsupervised operation and increased productivity. Powerful stirring for your lab reactions You can rely on the AREC.X 7 for demanding laboratory reactions, as it agitates volumes up to 15 liters (H2O), from 50 up to 1500 rpm, thanks to the powerful motor and magnetic coupling. The electronic control adapts the stirring speed to any variation in the viscosity of the medium. Absolute safety and ease of use for laboratory operators The AREC.X 7 hotplate stirrer guarantees a superior level of safety and protection for laboratory operators, since it is entirely made of technopolymer and is equipped with an extremely resistant ceramic plate, ideal for high resistance to acids, bases and solvents. When the platen temperature is above 50°C and the heating function is not active, a safety message is displayed. The control panel is positioned at a safe distance from heat sources and the technopolymer structure is carefully designed so that accidental spills of liquids cannot reach the electronics. The extremely durable ceramic soleplate is easy to clean and resistant to acids, bases and solvents. Using a damp cloth, all residues will be easily removed. Save time with the new control panel Thanks to the digital display, extremely bright and easy to read, it is possible to constantly monitor the temperature. Two new comfortable knobs: the left one for the temperature (up to 550°C), the right one for the stirring speed (up to 1500 rpm). The innovative low profile design for exceptional comfort above the bench and inside the laboratory hood.

THE TOP MODEL OF THE 5 SERIES Ideal for laboratories requiring precise sample temperature control an (more)d maximum reproducibility. The AREX 5 Digital magnetic stirrer is a beautiful instrument with a dual digital display for thermoregulating samples with an accuracy of ± 1.0 °C. Thanks to the VTF system then, it will be possible to achieve an accuracy of ± 0.5°C. Pt100 and Pt1000 probes are also available as an option. RESISTANCE, SAFETY AND PERFORMANCE The plate of the AREX 5 Digital Velp model is IP42 certified and is made of aluminum alloy coated with a ceramic layer, which guarantees protection from scratches and chemical agents, making it very resistant and easy to clean. It is therefore preferred in laboratories where acids, bases and solvents are used. Safety circuits and overtemperature protection guarantee complete protection for the operators. Two light indicators inform the user when the heating function is active. Even when the instrument is switched off, a safety message ('HOT') remains on the display until the plate temperature drops below 50°C. A further alarm will detect the presence of the probe. The plate structure and the insulating disc protect the internal parts and ensure high resistance to the most demanding laboratory environments and applications, for example when working with cold fluids (below 0°C). AREX 5 is designed to last over time and like most Velp products it is guaranteed for 3 years. THERMOREGULATION When a temperature probe is connected, it is possible to choose 2 different thermoregulation modes to satisfy all laboratory needs: - FAST: the set temperature is reached quickly - FINE: the set temperature is reached more slowly, minimizing the overshoot SHAKING AREX 5 is equipped with a powerful brushless motor for daily applications, being able to agitate up to 20 liters (H2O). It is also equipped with SpeedServo™ technology, which allows the speed to be kept constant even when the viscosity of the sample varies. The combination of the powerful brushless motor and the strong magnetic coupling ensure homogeneous stirring, even in the peripheral areas of the plate, guaranteeing a constant speed in all positions. DESIGN The compact, innovative and attractive design offers comfort and safety both during benchtop applications and in laboratory fume cupboards. The inclination of the front panel is designed to optimize the user experience and the bright LED display allows easy reading and constant monitoring of the temperature and stirring speed. APPLICATIONS AREX 5 is the ideal solution for temperature sensitive applications in many industrial, research and academic laboratory sectors. THE AREX DIGITAL PANEL: BEAUTIFUL AND SIMPLE TO USE By turning the left knob it will be possible to adjust the temperature up to 310°C, while with the right one it will be possible to set the stirring speed from 50 to 1500 rpm.
