CHOOSE THE SUITABLE ACCESSORY Choosing the right dispersing tool is essential to achieve maximum performance and high reproducibility. VELP dispersion tools are made of stainless steel (316L) and equipped with a PTFE seal, to be compatible with different types of samples and reagents. To handle different fluids, different dispersion tools are required. In some applications it is necessary to use two dispersing tools in order to achieve a final fineness level from coarse to fine. Thanks to a knob and a quick fastening system, inserting and changing the dispersion tool is simple and fast: in seconds you can switch from one application to the next. FOCUS ON THE PRODUCT What is a disperser? The disperser can be called in several different ways: homogenizer; Cell Lysor, High Shear Mixer, Polytron, Stator Rotor Homogenizer, Sonicizer or Tissue Tear. The various nomenclatures are due to the various uses of this tool and you have different results that can be obtained through the accessories. Essentially, a disperser is used to create a uniform mixture by forcing the sample through a narrow, confined space. Blade homogenizers, such as Velp's OV 625 Digital, use the blades as a rotor for dispersing. How does it work? The dispersing tool consists of a rotor rotating at high speed inside a stationary stator. The area between the rotor tip and the stator slot is called the shear gap. Thanks to the high circumferential velocity, the fluid is drawn axially into the dispersion head and forced radially through the cutting gap, breaking up the particles.

The N 840.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automatic conde (more)nsate 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.

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. APPLICATIONS AREX 5 is the ideal solution for temperature sensitive applications in many industrial, research and academic laboratory sectors. THE AREX DIGITAL PANEL: BEAUTIFUL AND SIMPLE TO USE By turning the left knob it will be possible to adjust the temperature up to 310°C, while with the right one it will be possible to set the stirring speed from 50 to 1500 rpm. COMPARISON TABLE OF THE NEW VELP SERIES 5 MAGNETIC STIRRERS:

Maximum Temperature Homogeneity The particular CerAlTop ™ plate, in aluminum alloy coated with a cer (more)amic layer, ensures a formidable temperature homogeneity over the entire surface of the plate itself, up to 370°C and at the same time excellent resistance to chemical agents and ease of cleaning. Fontal panel The control panel is extremely intuitive. 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). Maximum Protection, IP 42 AREX magnetic stirrers guarantee a high level of safety and protection for the user, also thanks to the raised control panel and the special channel for conveying liquids (in case of spills). 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. The particular geometry prevents accidental overflows of liquid being processed from entering the internal parts of the instrument. Thermoregulation of the liquid being processed For unmatched performance, AREX supports the VTF Fuzzy Logic digital temperature controller. VTF ensures perfect thermoregulations up to 300°C, given the very high level of accuracy of ±0.5°C. In addition, with VTF it is also possible to set the operating time, to better program the temperature control. Low Profile, Attractive Design AREX 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. AluBlocks ™, Greater Versatility AluBlocks ™ allow you to perform different heating and stirring experiments with unprecedented flexibility, acting on different types and sizes of tubes. Being modular, they are ideal for creating a workstation that is always customized, capable of supporting tubes of different formats. Made entirely of aluminum, they can be easily placed on the round head heating stirrers for excellent heat transmission and temperature homogeneity. A huge leap forward in productivity, while also saving time, money and counter space.
