Homogenizer for food and feed analysis
Achieve precise homogenization and particle size distribution with this high-speed benchtop solution, perfect for preparing samples with high water, fat, or fiber content, ensuring accurate analysis in demanding environments.

Homogenizes and Prepares Samples for Analysis
The Mixer B-400 from BUCHI is a versatile homogenizer designed for high-speed, bench-top sample preparation across a variety of industries, including food, feed, and microbiological testing. With its robust design, the Mixer B-400 excels in grinding and homogenizing samples with high water, fat, or fiber content, ensuring complete particle uniformity. Featuring an interchangeable knife system, it offers both stainless steel and inert ceramic options to prevent contamination during trace element analysis. This equipment supports microbiological testing by allowing for autoclave sterilization of components, maintaining sample sterility. It operates at a rotation speed of approximately 9,000 rpm, providing rapid processing while minimizing thermal decomposition. Safety features include a knife that only engages when the protective door is closed, achieving the GS mark for tested safety standards. For laboratories prioritizing efficiency, the Mixer B-400 ensures high recovery rates with minimal carry-over, supported by quick and contamination-free cleaning. Available with customization options such as borosilicate glass or titanium components for enhanced chemical compatibility, it integrates seamlessly into laboratory workflows, optimizing your analytical process chain.
