Mixer B-400

Optimized sample preparation

Mixer B-400 provides maximal homogenization efficiency at minimal effort. The user-friendly tool is essential for optimized sample preparation in your analysis process chain.

Application:Grinding and homogenization
Knife rotation speed:approx. 9'000 rpm
Knife material:stainless steel or ceramic

Flexible

Use the Mixer B-400 to grind samples even with high contents of water, fat or fiber. Perform trace element analysis thanks to the inert ceramic knife of the unit. Mixer B-400 is also suitable for microbiological testing using autoclavable materials, as well as for preparation of frozen samples thanks to its resistance to low temperatures.

Easy-to-use

The grinding process of the Mixer B-400 is straightforward, enabling you to easily use the unit. Benefit from automatic features, such as automatic speed adjustment in cases of unexpected high friction. Mixer B-400 is designed to meet the highest demands of safe operation and functionality during your optimized sample preparation steps.

Reproducible results

Mixer B-400 offers high recovery rates and low standard deviations thanks to excellent particle size distribution. The unit has short griding times, eliminating thermal decomposition. Prevent carry-over effects by easily and quickly cleaning your unit. Work contamination-free using the high-quality knife made of inert materials.

Save time and money
The BUCHI Mixer B-400 reduces the number of essential analyses per sample due to the complete homogeneity of samples.
Special version for the trace element analysis
For trace element analysis, the homogenized sample must be free of contamination. The Mixer B-400 is available with components in contact with the sample made of borosilicate glass, inert plastics (PP and PEEK), or titanium. The cutting knife is high quality ceramic.
Microbiological sample testing
For microbiological sample testing, sterility is an absolute requirement. A PVDF membrane permits autoclave sterilization of all components contacting the sample.
Unmatched safety
The B-400 has been awarded the official GS mark for "Tested Safety" - meeting maximum requirements on safe operation and functionality. A major feature: The knife of the mixer can only rotate with the safety door closed. If the door is opened while mixing is in progress, the knife stops automatically.
