Achieve More, Experience More in your dispersion, homogenization and mixing challenge

The OV 725 Digital incorporates state-of-the-art technologies to change your dispersing experience, providing high shearing force, effortless operations, and lasting durability for excellent homogenisation, emulsification, suspension and mixing performance.

Thanks to a wide offer of dispersing tools, the OV 725 Digital seamlessly adapts to various applications with volumes ranging from 0.2 ml to 2.5 L (H₂O) and up to 5,000 mPas viscous samples.

Whatever your laboratory challenges, you can rely on a high-performance disperser ensuring excellent mechanical properties and chemical resistance.

Superior Performance and Lasting Durability

The OV 725 Digital features an extremely powerful brushless motor running from 2.000 up to 25.000 rpm ensuring higher instrument speed accuracy and fast response time.

The brushless motor also results in less noise, minimized maintenance needs and reduced internal friction, due to the absence of brushes, which makes it more effective and resistant over time. The efficient motor is also capable of more easily dissipating heat, reducing the risk of instrument overheating.

The rugged housing and the robust structure protect all internal electronic components, enabling proper operations in the most challenging conditions and making the OV 725 Digital a solution designed to last, guaranteed by a 3-year warranty (online product registration required).

Effortless Precision and Reliable Monitoring

The OV 725 Digital is the ideal disperser for applications with the highest demands for reproducibility. The bright and intuitive 4-digit LED display and the comfortable push-to-start knob allow for easy and precise speed setting.

The control panel is designed to optimize the user experience: the speed parameter is visible at a glance to provide excellent visibility in every working condition.

The cyclic digital timer (up to 99:59 hours) enables unattended operations and easy processing of large samples in series, guaranteeing optimal performance, high reproducibility and preventing samples from overheating.

Ultimate Safety in Daily Operations

Various safety features provide maximum protection for the user in daily operations. Once the set point speed is set, the OV 725 Digital ensures a soft start-up to reach the desired speed gradually.

In addition, dedicated alarms notify users of potential risks, such as overtemperature and motor failure, while a specific dispersing tool detection alarm alerts the operator for improper installation or lack of the dispersing tool.

Smart Maintenance and Quick Installation Dispersing Tools

Choosing the proper dispersing tool is crucial to achieve the best performance and high reproducibility. The VELP dispersing tools are manufactured with stainless steel (316L) and fit a PTFE seal to be chemically compatible with different samples and reagents.

The OV 725 Digital homogenizer features a LED indicators system and a maintenance timer that notifies users about the worn equipment, ensuring timely replacements to maintain its integrity and minimize downtime.

In addition, thanks to a knob and the quick installation system, it is possible to change the dispersing tool in a breeze and get ready for the following application in a while.

Aflatoxin test: how to homogenize the sample for testing

Aflotoxins are microtoxins; they have genotoxic and carcinogenic properties and for this reason, their content in foods must be as low as possible. Typically, these toxins are found in food products such as peanuts, tree nuts, corn, rice, candied fruit, etc. as a result of contamination that can occur at different times during the collection cycle. In this context, each sample must be very thoroughly ground and mixed thoroughly using a process that demonstrates complete homogenization is achieved.

Dispersion of Xanthan Gum for the Production of Cosmetic Creams

Dispersion is a crucial step in cosmetic product preparation and high-shear dispersers are essential to achieve a stable emulsion. Through dispersers, consistent product quality and repeatability, agglomerate-free mix and rapid dispersing time are obtained.

Preparation of a Lipstick

Tissue homogenization for biological and medical research

Tissue homogenization is a sample preparation process in which animal and plant cells, or microorganisms are prepared prior to extraction of intracellular substances such as proteins, DNA or RNA. The cell membrane has to be ruptured to release the contents of the cell. In order to test the samples with chemical and physical analyses, samples are homogenized to an appropriate degree of fineness and uniformity
