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.

Laboport SD N 860.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automat (more)ic condensate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products. The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications. When the humid gases are sucked in, it can happen that condensation forms in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection. Technical features Flow rate (max.) 60 l / min Final vacuum (max.) 4 mbar (abs.) Pressure (max.) 1 bar (rel.) Fluid temperature allowed at 5-40°C FFPM valve material PTFE coated diaphragm material Pump head material PTFE Applications Rotary evaporation Centrifugal concentration Distillation Vacuum oven Qualitative characteristics Clean operation, 100% oil-free Corrosion resistant PTFE / FFPM flow path Ideal for extremely aggressive / corrosive gases and vapors Compact, silent and reliable The self-drying system removes condensation without altering the vacuum level Maintenance free Download the data sheet for further information and accessories.
