Metrohm stirrer

Powerful stirring for your lab reactions AREC features state-of-the-art heating plate technology, de (more)signed by VELP, which guarantees temperature homogeneity, thermal efficiency and long-lasting heating performance. You can rely on the AREC for demanding laboratory reactions, stirring 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. SAFETY AND EASE OF USE FOR LAB OPERATORS The AREC stirrer with heating plate guarantees a superior level of safety and protection for laboratory operators, as 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 plate 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 plate is easy to clean and resistant to acids, bases and solvents. Using a damp cloth, all residues will be easily removed. SAVE TIME AND SPACE WITH THE NEW CONTROL PANEL Thanks to the extremely bright and easy-to-read digital display, the temperature can be monitored constantly. Two new comfortable knobs: the one on the left for the temperature (up to 550°C), the one on the right for the stirring speed (up to 1500 rpm). The innovative low profile design for exceptional comfort above the bench and inside the lab hood. It is not possible to connect AREC to the Cloud Ermes system.

Digital Display, Total Control of Operations AREX Digital PRO is the evolution of our best-seller, t (more)he most advanced tool available to date. By turning the left knob it is possible to adjust the temperature (up to 370°C), while with the right one you can act on the agitation (up to 1500 rpm). The SpeedServo ™ system ensures a constant speed even when the viscosity varies (counter-reaction). AREX Digital PRO offers the most advanced technology, being equipped with digital displays to set and monitor both stirring speed and temperature constantly and with absolute precision. Temperature regulation of the liquid being processed with an external probe The AREX Digital PRO package includes the external Pt100 probe, capable of reaching 250°C, with an accuracy of ±1.0°C, providing a ready-to-use system capable of directly thermoregulating the sample being processed. Previous model video: Maximum Temperature Homogeneity The particular CerAlTop™ plate, in aluminum alloy coated with a ceramic layer, ensures a formidable homogeneity of the temperature over the entire surface of the plate itself, up to 370°C and at the same time an excellent resistance to chemical agents and ease of cleaning. Maximum Protection, IP 42 AREX Digital PRO magnetic stirrers guarantee a high level of safety and protection for the user. The control panel is easily accessible, away from heat sources that are dangerous for the operator and protected from any liquid leaks by means of a special conveyor channel. AREX Digital PRO can be programmed with a maximum safety temperature, for some particular applications that require specific temperatures and in order to prevent unpleasant situations. In addition, the electronic board activates a high temperature warning ('Hot Plate Warning') which remains active even with the instrument off, when the plate temperature is above 50°C. The particular geometry prevents accidental overflows of liquid being processed from entering the internal parts of the instrument. Low Profile, Attractive Design AREX Digital PRO offers an innovative low profile and a highly attractive design for greater comfort for the user. Even the inclination of the front panel has been carefully studied to facilitate its use and make it clear that the digital displays indicating speed and temperature can be read.

The first hot plate stirrer with embedded Wi-Fi technology Wherever you are, VELP Ermes allows the r (more)eduction of routine operations thanks to the real-time control of your AREX-6 Connect PRO. Access your analyzes from PC, Pad or smartphone, to maximize the productivity and reproducibility of your reactions. Immediate notifications and alerts will allow you to always be informed and thanks to the remote interruption you will have total control of your processes. SAFETY FIRST AREX-6 Digital PRO is equipped with 2 independent temperature reading circuits that protect the instrument in the event of a malfunction of one of the two. If the probe is not inserted into the sample being analyzed, the instrument stops heating, showing a safety message on the display. AREX-6 Digital PRO is equipped with the most advanced technology and allows you to set the maximum temperature limit required for analyzes with specific temperatures. The Lock function prevents inadvertent changes to settings by locking the instrument. 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. CUTTING-EDGE THERMOREGULATION AREX-6 Digital PRO offers the best thermoregulation available. The PID thermoregulation system guarantees stable, fast temperature control with minimal overshoot. VTF and Pt100 probe allow accurate and precise temperature control. It is possible to choose between 2 different thermoregulation modes: - FAST: The set temperature is reached quickly. - FINE: The set temperature is reached slowly, minimizing overshoot. 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 Digital PRO is an IP42 product designed to guarantee years of use and resistance in the laboratory.

OHS are designed to ensure the highest safety standards. The resistant sealed case and the IP 54 deg (more)ree of protection guarantee durability over time even in the most aggressive environments. Continuous trouble-free operation in your lab, backed by a 3-year extended warranty. Constant torque at any speed The powerful brushless motor and microprocessor control ensure unprecedented performance, highlighting the difference between a conventional shaft stirrer and VELP OHS Series shaft stirrers. Thanks to the SpeedServo feedback system, the torque remains constant at any speed, even at maximum. Always having a constant torque is a very important parameter for the reproducibility of the analyses. SmartChuck Technology: Inserting or Removing an Auction Has Never Been So Simple! How often do you have to remove or replace the stirring rod using two hands and see the rod drop into the liquid? SmartChuck™ technology makes this activity quick and easy with just one hand and no special accessories. Two simple movements allow you to unlock the protective ring and remove or replace the stirring rod. If the protection ring is opened during the analysis, the instrument interrupts the stirring, showing a safety message on the display. Maximum Protection and Security OHS Advances guarantee the highest safety standards. The IP54 degree of protection ensures maximum protection of the instrument from corrosion and high performance in challenging work environments. The stirring is activated through pressure, avoiding involuntary start-ups and the set speed is reached gradually. The large number of sensors and safety controls deactivate the stirring in case of overload, overheating or short circuit. Integrated Timer to Schedule Your Activities The OHS Digitals are equipped with timers that allow you to program the stirrer according to your needs and to carry out the reactions independently. Setting the timer is quick and easy, just press the dedicated button and select a time interval between 1 min and 99:59 hours.
