The 4E’s USA Handheld Rotor-Stator Homogenizer can rapidly homogenize biological samples and handle sample volumes ranging from 0.1ml to 250ml, depending on the generator probe used. The rotor rotates rapidly within a stationary stator. This creates a suction effect, and the sample is drawn into the space between the two components, where it is subjected to high shear forces thereby homogenizing the samples.
The device is driven by a powerful 160W motor that provides variable speed from 8,000 to 30,000 rpm and comes with 10 speed levels to meet your sample processing needs. Unique ergonomic design and lightweight allow hand-held operation without fatigue. The homogenizer probe, made of 316L stainless steel, is corrosion-resistant and fully autoclavable.
The Handheld Rotor-Stator is designed for ease of use with one hand. Its portability makes it convenient for various applications, whether in a laboratory setting or in the field. Its variable speed settings (from 8,000 to 30,000 rpm) allow for precise control over the homogenization process, making it suitable for various applications such as sample preparation for DNA extraction, protein analysis, and more.
Additionally, it comes with generator probes available in 5mm, 7mm, and 10mm diameters, catering to a wide range of sample sizes and types.
The Rotor-Stator Homogenizer is:
| Speed range | 8000 ~ 30000 rpm |
| Working Volume | 0.1 ~ 250 ml |
| Max. linear speed of rotor | 6.3 - 14 m / sec |
| Max. viscosity | 5000 mPas |
