Dispersion

Dispersion involves the mixing of different substances that combine with each other to little or no effect. Conventional processes include the dispersion of solids in liquids (producing a suspension) or the mixing of two immiscible liquids (producing an emulsion). To achieve efficient dispersion, the substances to be dispersed (disperse phase) are first distributed as well as possible in the matrix phase (continuous phase). For this purpose, they should be wetted beforehand so that the interfacial tension is reduced. The substances to be dispersed are then broken down into very small particles and subsequently stabilized in this dispersion state.

How a disperser works in the laboratory

Laboratory dispersers assist the mixing of the different substances by introducing shear energy into the mixture to be dispersed. This can be done either by friction of the material to be ground between two surfaces or by introducing impact forces through rapidly rotating disks. Homogenizers based on the rotor-stator principle are most commonly used. Here, the mixture is transported through the toothed rotor into the dispersing tool, rotated in a radial direction and then pressed through the stator slots. The resulting turbulent flows lead to a very effective and fast result.

Dispersing unit - areas of application and tasks

Dispersing processes are of great importance in many industrial sectors, among others. One example is the production of paints and coatings: Here, pigments must be incorporated in sufficient fineness. Other industries in which a laboratory disperser is used include the cosmetics industry for the production of creams and lotions, as well as the food industry. In addition, samples also need to be dispersed in medical and biochemical laboratory applications, for example in cell analysis, blood tests or the dispersion of organisms.

Laboratory Dispersers and homogenizers - design variants

Depending on the application, the requirements for the dispersing aggregates and thus the properties of the devices can differ significantly. The main differences are the achievable speed, the volumes to be dispersed, and the size and handling.

Disposable homogenizer

Single-use homogenizers are hermetically sealed and minimize contact from the laboratory worker to the mixture to be dispersed. They have the advantage that the time-consuming cleaning process is eliminated. This saves you time on the one hand, and also virtually eliminates contamination and impurities. Therefore, these homogenizers are particularly suitable for very sensitive or toxic materials. In our online catalog, for example, you can obtain the IKA Ultra-Turrax Tube Drive.

Hand disperser

Hand dispersers are optimal for small sample quantities and are therefore mainly used in laboratories. Due to their low weight, they are very ergonomic in the hand and optimally disperse biochemical or medical samples at particularly high speeds. An example of a handheld disperser is the X 120 from the engineering company CAT M. Zipperer.

High-performance disperser

High-performance dispersers are optimal for larger sample quantities and are characterized by their high applied energies. High-performance dispersers can reach speeds of over 9000 rpm and sample volumes of up to 50 liters. Therefore, these are optimal for higher viscosity mixtures. One homogenizer you can purchase at MedSolut.com is the IKA T 65 digital ULTRA-TURRAX.

Tripod disperser

Tripod dispersers are attached to a tripod and thus stabilized. They are the all-rounders among the dispersers. Sample volumes from 0.2 milliliters up to 20 liters can be mixed efficiently, the speed range covers the complete bandwidth from 2500 rpm up to 33000 rpm. On MedSolut.com you can purchase the dispersing drive Unidrive X 1000D from the engineering company CAT M. Zipperer GmbH, among other devices.

Buy a Laboratory Disperser - Manufacturer in the assortment at MedSolut.com

The product range at MedSolut.com contains a wide variety of different dispersers and currently focuses on the two brand manufacturers Ingenieurbüro CAT M. Zipperer and IKA. Both manufacturers are briefly introduced below.

IKA

The IKA Group has been in existence since 1910 and is the world market leader in most product classes. With eight locations on four continents and more than 900 employees, the manufacturer stands for development, innovation and growth. Major customers such as BASF or Bayer rely on IKA's technologies, which stand out for their high quality and functionality. With the Ultra Turrax product group, IKA covers a wide range of dispersing equipment.

Engineering office CAT M. Zipperer

Since 1976, Ingenieurbüro CAT M. Zipperer has been developing custom-fit solutions for laboratory applications. High-precision systems with high quality standards characterize the product range. At MedSolut.com you can currently choose from an extensive range of high-quality stand dispersers and hand dispersers.

Accessories for the disperser

At MedSolut.com, we also offer matching accessories for all homogenizers. Thus, you can optimally adapt your device to your requirements. Accessories available for a laboratory disperser include dispersing tools, stands, mixing cups, cross clamps and knife rotors.  

• Dispersing tools: These tools complement the existing dispersing drives and are used to precisely crush and mix the material. Choose different tools to attach to the homogenizer so that the tool optimally fits the sample volume and the material to be dispersed.
• Mixing cups: These serve as accessories for disposable dispersers. Together with the matching lids, they ensure that contamination-free and clean work can be carried out.
• Cross clamps and tripods: Tripods in various sizes with the appropriate cross clamps are available for attaching tripod devices.
• Knife rotors and stators: For rotor-stator systems, knife rotors or stators can be purchased to replace existing systems
