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.

These options guarantee a modern and smart experience, increase the versatility of data collection and transfer functions. Other standard features and equipment Transport lock, stainless steel weighing pan, menu and setting lock switch, adjustable and non-slip feet, bubble level, software and mechanical overload/underload protection, stability indicator, automatic tare, level indicator low battery, auto power off, user selectable print options and communication settings. Applications Weighing: Determines the weight of the items on the pan in the selected unit of measure. Piece Counting: Count the number of pieces on the pan using a uniform weight. Percent Weighing: Measures the weight of a sample displayed as a percentage of a pre-set reference weight. Check Weighing: Compares the weight of a sample against target limits. Dynamic Weighing: Weigh an unstable sample load. The balance takes an average of weights over a period of time. Totalization: Measures the cumulative weight of multiple items. Cumulative total may exceed balance capacity. Density Determination: Determines the density of solids or liquids. With the integrated weigh below hook, specific gravity tests can be performed for items that cannot easily be placed on the weighing pan. Display Hold: Manually holds the last stable weight or the first highest stable weight value on the display. Mole Weighing: Measures the weight of a sample and automatically calculates it into the mole.
