A homogenizer is a laboratory or industrial instrument used for the homogenization of various types of materials, such as fabrics, plants, food, soil and many others.
The OV 725 Digital laboratory disperser, thanks to the powerful brushless motor, adapts to various applications with volumes ranging from 0.2 ml to 2.5 L (H2O) and viscous samples up to 5,000 mPas. It 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 4-digit LED display and rotary knobs allow you to precisely adjust the speed between 2,000 and 25,000 rpm in 100 rpm steps. Clear speed information on a black background facilitates visibility in all conditions.
Furthermore, the convenient cycling digital timer will allow you to operate unattended, maximizing laboratory efficiency and productivity.
SAFE AND RESISTANT
Safety functions guarantee maximum protection for the operator. For example, once the set point speed is set, the OV 725 Digital will gradually reach it. Furthermore, several alarms warn the user in case of overload and overtemperature and the resistant and airtight structure allows correct operation even in the most difficult conditions.
The LED indicators and maintenance timer will remind you when the internal seal of the dispersion tool needs to be replaced.
The equipment is completed by a guarantee of up to 3 years (subject to registration).
Other security features:
For maximum comfort, choose the model with the double-rod stand, it will allow you greater mobility and ease of use of the instrument.
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 725 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.
