VWR 620 Standard 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. 1 - Aluminum alloy plate with ceramic coating 2 - Main switch 3 - Speed control knob 4 - Temperature control knob 5 - Display A - Probe led B - Temperature setpoint led La piastra riscaldante realizzata in alluminio con rivestimento in ceramica, conferisce: • Ottimale distribuzione del calore con una elevata potenza specifica grazie alla configurazione circolare • Ottima omogeneità di temperatura in tutti i punti della piastra • Elevata resistenza a fatica termica e shock termici • Elevata resistenza ad agenti chimici e abrasioni superficiali COMPARISON TABLE OF THE NEW VELP SERIES 5 MAGNETIC STIRRERS

AREX 6 by Velp Scientifica The central button activates the heating of the plate only after pressing (more) it, avoiding involuntary switching on. The safety icon informs the operator that the plate is at temperature, preventing possible burns. It will remain illuminated until the temperature is below 50°C. The knobs allow precise speed and temperature regulation with new ergonomics and greater sensitivity. CerAlTop™, High Resistance The CerAlTop™ plate, made of aluminum alloy covered with a ceramic layer, guarantees a homogeneous and fast heat transfer over the entire surface. Furthermore, the thin ceramic layer protects the straightener from scratches and chemicals. UNPRECEDENTED PERFORMANCE The brushless motor allows you to shake up to 20 liters at an adjustable speed from 30 to 1700 rpm. Thanks to the SpeedServo™ system, the speed is kept constant even when the viscosity varies. The Alnico magnet guarantees homogeneous agitation, even in the peripheral areas of the plate and a powerful magnetic coupling between motor and stir bar, a very important aspect when using accessories. MAXIMUM INSTRUMENT PROTECTION AREX 6 is an IP42 product designed to guarantee years of use and resistance in the laboratory. The structure and materials protect the internal parts of the instrument from possible damage. AREX 6 is guaranteed for 3 years. The silicone cover ensures further protection of the instrument from possible spills or splashes. ACCESSORIES OIL BATH AND HEATING MANTELS REPLACED WITH SPHERICAL CAPS The new Spherical Caps are the perfect solution for replacing oil baths and heating mantles. Furthermore, they adapt perfectly to both the 135 mm plate diameter and the shape of the tubes allowing a fast heat transfer from the plate to the tube. To increase protection and reduce thermal dispersion, VELP has designed the new PTFE Covers. GREATER VERSATILITY The MultiAlublock™ and the new MonoAlublock™ made of aluminium, are ideal for carrying out numerous stirring and heating analyses, reducing time and space in the laboratory. - MonoAlublock™ are the ideal solution for all those applications that require analysis in tubes of the same size. - MultiAlublock™ are modular and of different types to support various tube sizes. Thanks to their modularity, it is possible to choose the mix that best suits your needs

Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate The Heidolph 036110 (more)233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate paves the way for future-oriented working practices: thanks to its equipment with numerous interfaces, it meets all requirements for digitalization and network. The RS232 and USB B interfaces allow control via our Hei-Control software, free of charge, as well as our Hei-PROCESS solution. With the LAN interface, you can directly integrate the device into a network, whereas the USB A interface located at the front allows data logging via USB stick. Use the USB C interface and combine the magnetic stirrer with the electric Heidolph Lab Jack to work even more comfortably and securely. For controlling the temperature, you can choose between three heating modes: FAST for a particularly quick heating, as well as PRECISE and PRECISE+ for a particularly exact control of your target temperature without overshoot - this is how sensitive samples are optimally protected. Therefore, the device is compatible with the temperature sensor Pt1000 as well as the double sensor Pt1000 that allows the measurement in your sample and in the bath liquid simultaneously. The possibility to program ramps and to create profiles gives you full control and increases the precision and reproducibility of your experiments. For the stirring speed, there is a three-stage setting (start-up behavior). Furthermore, you can set the rotational direction of the magnetic stirring bar and benefit from the automatic stir bar detector. As a result, your sample is optimally stirred at any time, even when there are irregularities while stirring. This magnetic stirrer is equipped with the most important safety features. The large safety distance between the heating plate and the control panel, as well as the visual residual heat indicator at temperatures 50°C, protect against burns. The patented Kera-Disk® plate made of anodized aluminum is chemical-resistant, scratch-resistant and has a diameter of 145 mm. This unique size makes it suitable for use with many accessories and samples on a small footprint. Moreover, the material used allows the fastest heating times.
