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. COMPARISON TABLE OF THE NEW VELP SERIES 5 MAGNETIC STIRRERS:

AREC 10 Digital was designed for laboratory applications where a comfortable and large work surface  (more)is required, which here reaches 26x26 cm in size, the largest among the Velp series. The plate offers high resistance to acids, bases and solvents, while the technopolymer structure of the stirrer is designed to prevent accidental spills of liquids from reaching the electronic components, ensuring easy and quick cleaning. This translates into product safety and durability even in the most demanding laboratories; further protected by a 3-year warranty (subject to online registration). The heating uses the latest technologies available and ensures a uniform temperature across the entire plate and exceptional transfer efficiency. Same quality for agitation: SpeedServo™ technology and brushless motor offer precise and powerful agitation even when viscosity varies. In short, why we offer you AREC 10 Digital: - Easy to use and highly resistant to chemicals - Precise setting of temperature and agitation - Accepts volumes up to 25 liters / 30 kg - Possibility of precise thermoregulation of the fluid with Pt100/Pt1000 and VTF probes - Designed for durability and guaranteed for 3 years The powerful brushless motor of the AREC 10 Digital ensures stable and reliable stirring. The patented SpeedServo™ technology ensures constant speed even with variations in fluid viscosity. The always precise stirring speed, from chemical reactions to sample preparation, adjustable from 100 to 1500 rpm, it is ideal for any laboratory need. With a stirring capacity of up to 25 liters (H2O) (or 30 kg of liquid), the AREC 10 Digital stands out for its robustness and superior performance. Arec 10 reaches the remarkable temperature of +550°C in complete safety and control. Extremely precise, you can increase the temperature by +1.0°C. By connecting the external PT100 or PT1000 sensors you can directly thermoregulate the sample up to 350°C with an accuracy of ±1.0°C. Using VTF Digital instead you can control the temperature with a precision of ±0.5°C (up to a maximum of 300°C). In this regard, Arec 10 is available with different accessory packages. You will find all the combinations at the bottom. Safety during rescaling: - 'Hot surface' alarm when temperature exceeds 50°C, even when inactive. - Overtemperature alarm above 570°C 1 - Aluminum heating plate with ceramic coating 2 - Main switch 3 - Knob for stirring setting 4 - Knob for temperature setting 5 - Display
