Rotor–stator disperser for homogenization, dispersion and emulsification
The XHF-DY Laboratory High-Shear Mixer is suitable for a wide range of laboratory applications in medicine, bioengineering, cell research, the food industry, and cosmetics manufacturing. It effectively homogenizes and mixes animal and plant tissues. Its variable speed settings allow the disruption of different types of cells. The device also enables efficient dispersion, emulsification, and extraction between immiscible liquid phases. High-speed dispersion significantly reduces sample processing time, improving laboratory efficiency. At its lowest speed, the device can be used as a mixer.
Operating Principle
The XHF-DY high-speed disperser uses an electronically controlled high-speed motor and a rotor–stator system with plum-blossom-shaped cutting elements. The high-speed rotation of the internal cutting tool enables homogenization, emulsification, and disruption of materials.
A rotor–stator mixer is a high-shear mixing device in which a rapidly rotating rotor operates inside a stationary stator. Material passes through the narrow gap and stator openings, where intense shear promotes homogenization, emulsification, and the breakdown of agglomerates.
Unlike a conventional mixer, which mainly blends and circulates material, or a dissolver, which uses an open, high-speed toothed disc, a rotor–stator mixer concentrates shear within its mixing head. It generally provides higher local shear but less bulk circulation than a dissolver, making it particularly suitable for fine emulsification and homogenization.
Technical Specification
