VELP AREX 5 CerAlTop™ Hot Plate Stirrer

Overview

The AREX 5 is a robust and versatile hotplate stirrer suitable for applications ranging from basic to temperature-sensitive where precise sample thermoregulation is required. The AREX 5 can work stand-alone or be upgraded to digital by connecting the VTF digital temperature controller. The CerAlTopTM plate reaches a maximum temperature of 310°C; when connected with the VTF, the AREX 5 is able to thermoregulate the medium up to 300°C with an accuracy of ± 0.5 °C.

Features:

• Two illuminated indicators always inform the operator when the heating is on. Furthermore, the icon stays on when the temperature of the plate is above 50°C even if the instrument is switched off.
• The internal electronic parts are protected by the insulating disk, which, together with the robust die-cast aluminum housing, enables the AREX 5 to withstand even the most demanding laboratory environments and applications, such as when working with cold media (below 0°C).
• The 135 mm diameter top is protected from chemicals and scratches by the superior resistant CerAlTop™ ceramic coating.
• IP42 certified and it is backed up by a 3-year warranty (online product registration required).
• You can rely on the robust AREX 5 and its powerful brushless motor for everyday laboratory applications like sample and buffer solutions preparation, as it stirs volumes up to 20 liters (H2O).
• By turning the right knob of the AREX 5 it is possible to easily adjust the stirring speed from 100 up to 1500 rpm.
• The AREX 5 is equipped with VELP-engineered SpeedServo™ torque compensation technology that ensures constant speed even when the viscosity of the medium changes.
