Velp Scientifica AREX 5 DIGITAL VTF – AREX 5 Digital Hot Plate Stirrer with VTF Digital Thermoregulator, 115V/60Hz

• AREX 5 versatile digital hot plate stirrer with CerAlTop plate
• VTF digital thermoregulator for precise sample thermoregulation
• Stirs up to 20L from 100 to 1500 rpm with SpeedServo counter-reaction
• 2 illuminated indicators inform the operator when the heating is on, and the temperature is above 50 degrees Celsius
• Brushless motor ensures power and resistance over time

The Velp Scientifica AREX 5 DIGITAL VTF is an ideal solution for temperature-sensitive laboratory applications where precise and accurate thermoregulation of the sample is required to ensure maximum reproducibility. The AREX 5 Digital can be connected to external probes Pt100 and Pt1000 (sold separately) or to the VTF (included) for precise temperature control of the medium.

The CerAlTop plate reaches a maximum temperature of 310°C; when connected with the temperature probe (Pt100 or Pt1000) the AREX 5 Digital can heat the medium up to 310°C with an accuracy of ± 1.0°C, while with the VTF the AREX 5 Digital is able to heat up the medium up to 300°C with an accuracy of ± 0.5°C.

When the hotplate stirrer is connected to a temperature probe, it is possible to choose from two different thermoregulation modes to meet your requirements:

FAST: the Hot Plate Stirrer quickly reaches the set point temperature with a little overshoot

FINE: slower temperature set point reaching with an optimized overshoot

You can rely on the powerful brushless motor of the AREX 5 Digital for all your laboratory reactions as it stirs volumes up to 20L (H2O).

Speed setting is precise, ranging from 50 to 1500 rpm making the AREX 5 Digital suitable for both low and high-speed applications.

The AREX 5 Digital is equipped with VELP-engineered SpeedServo torque compensation technology that ensures constant speed even when the viscosity of the medium changes.

The AREX 5 Digital hot plate stirrer ensures a high level of safety and protection for laboratory operators.

The internal electronic parts are protected by the insulating disk, which, together with the robust die-cast aluminum housing, enables the AREX 5 Digital to withstand even the most demanding laboratory environments and applications, such as when working with cold media (below 0°C).

The 135mm diameter top is protected from chemicals and scratches by the superior resistant CerAlTop ceramic coating.

Various safety functions protect users in their daily operations, such as safety circuits, over-temperature protection, and probe detection alarm. It is also possible to limit the maximum operating temperature to meet the highest safety needs.

A security message “Hot” is displayed when the temperature of the plate is above 50°C and the heating function is not active.

With an extremely bright and easy-to-read digital display, you can constantly monitor the temperature and the stirring speed and set them with the highest precision.

The inclination of the front panel has been carefully designed to optimize the user experience for all the lab users and to clearly read the values shown on the digital displays.

To set the temperature and stirring speed it is required to turn and push the knobs for maximum safety.

The VTF thermoregulator is ideal for many applications and meets the most demanding requirements in terms of precision, reliability, and flexibility of use thanks to the innovative FUZZY LOGIC Technology. It automatically adjusts the thermoregulation to different factors such as power, load, and thermal dispersion.
