Ohaus Guardian 2000 Hotplate Magnetic Stirrer

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.
