A homogenizer is a laboratory or industrial instrument used for the homogenization of various types  (more)of materials, such as fabrics, plants, food, soil and many others. The OV 625 Digital laboratory disperser guarantees the highest level of reproducibility for a wide range of laboratory applications. Cutting-edge technology and engineering, like all Velp scientific products, guarantee precision and high shear force for rapid homogenization, emulsification, suspensions and high-speed mixing of biological tissues, pharmaceuticals, cosmetics and food products. Excellent mechanical properties and high chemical resistance make it suitable for even the most demanding laboratory challenges. DISPLAY AND CONTROL Bright, intuitive LED display and rotary knobs allow you to fine-tune the speed between 3,000 and 25,000 rpm. Clear speed information on a black background aids visibility in all conditions. SAFE AND RESISTANT Safety features ensure maximum operator protection. For example, once the set point speed has been set, the OV 625 Digital will reach it gradually. In addition, various alarms warn the user in case of overload and overtemperature. The resistant and hermetic structure allows correct operation even in the most difficult conditions. Warranty up to 3 years. For maximum comfort, choose the model with the double pole stand. 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.

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.
