1499 – Used Buchi Mixer B-400

This used BUCHI mixer B-400 is designed for efficient homogenization of a wide range of food and feed samples. The achieved homogeneous analytical fineness is key for the quality of the subsequent analytical procedures. The mixer is tested and is working, the only thing that is not working is the light in the power button but this does not affect the performance.

The process is based on simultaneous grinding and homogenization of sample materials by means of volumetric reduction using two rotating blades in a beaker (included). Automatic electronic monitoring of the speed and the torque allows safe and straightforward operation of the grinding process.

Procedure:

• Sample material is placed into the beaker, beaker goes in position, safety door is closed.
• Beaker moves up to the knives
• As soon as the knife assembly is inside the beaker, it begins to spin
• When maximum speed is reached, the beaker moves further up to the blades
• The driving speed is automatically adjusted by means of the membrane counterpressure
• The sample is grinded and homogenized
• When finished, the beaker moves down far enough for the knives to coast to a stop while still being inside the beaker
• The beaker moves further down to the starting point
