Heating thermostat from 35°C to 250°C for professional thermostats LAUDA PRO is a cutting-edge produ (more)ct line, designed to be the laboratory tools of the future. A significant innovation was the division between thermostats dedicated to internal applications and those dedicated to external applications. Then, the choice of offering products with tanks of a few liters allows the operator to quickly reach the desired temperature. New criteria have also been adopted for the design of the control panels. Two operational approaches are available, Basic, with OLED screen and essential but professional features, and Command Touch (named 'C'), the ultimate in the LAUDA experience, with touch display, graphic displays and numerous functions. In either case, the control panel can be removed from the thermostat for maximum operational flexibility and a noticeable decrease in instrument height. All thermostats are equipped with an Ethernet, USB interface and a Pt100 connection as standard. Cooling thermostats are also available with natural refrigerants. In addition, as standard, they are equipped with a cooling system that allows a lowering of the thermostat temperature with water. Notable features - Removable control panel for remote control - Stainless steel bathtubs (insulated with handles and drain tap) - 8-stage LAUDA Vario internal pump - Ethernet interface, USB and Pt100 connection as standard - Drain cock on the front of the device Accessories included Tank covers, pipe fittings with screw caps for the cooling coil Graph of heating performance of PRO P LAUDA thermostats.

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. The structure and materials protect the internal parts of the instrument from possible damage. AREX-6 Digital PRO is guaranteed for 3 years. The silicone cover ensures further protection of the instrument from possible spills or splashes.

NEW INTERFACE - EASY USE Bright LED display and intuitive icons. The icons will show you: probe or thermoregulator connection, heating activation, reaching the set temperature, timer activation and rotation reversal. The speed and temperature are set by the sensitive knobs, and are activated only after they are pressed. AREX-6 Digital PRO is equipped with an advanced menu that allows you to configure the instrument with the features that best suit the needs of the individual laboratory. INTEGRATED TIMER AND ROTATION REVERSE The central button allows you to set the timer from 1min to 99h59min. You can set the timer in 2 different modes: - Snap: The timer starts counting down as soon as a function is activated (stirring or heating). - SetP: The timer starts counting down as soon as the set temperature is reached. Furthermore, it is possible to set the rotation reversal at time intervals. 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.

Optical and acoustic alarm for low water level and over/under temperature as well as sensor breakage/short circuit. Optimized space, safety and comfort of use. Connection for water level regulator (available as accessory). Water circulation The circulation system guarantees optimal temperature distribution throughout the tub. It is managed by a magnetic electric motor which transmits the rotation to a PTFE-coated stirrer in the tank. The agitator draws the water towards the center and then distributes it to the rest of the tank. The water circulation is activated via the main switch. Recommended accessories - Water level regulator. The water regulator located on the back of the water bath is used to maintain constant the set water level during water loss due to evaporation. Furthermore, it allows use at temperatures below ambient temperatures, with a minimum of approx. 3°C above tap water temperature.
