Mixer B-400

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.  

Flexible

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. 

Easy-to-use

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.

Features

  • The BUCHI Mixer B-400 reduces the number of essential analyses per sample due to the complete homogeneity of samples. 

    Save time and money
  • 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.

  • For microbiological sample testing, sterility is an absolute requirement. A PVDF membrane permits autoclave sterilization of all components contacting the sample.

  • 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.
