The Mixer Mill MM 400 is a true multipurpose mill designed for dry, wet and cryogenic grinding of small volumes up to 2 x 20 ml. It mixes and homogenizes powders and suspensions with a frequency of 30 Hz within seconds – unbeatably fast and easy to operate.

The compact benchtop unit is suitable for classic homogenization processes, as well as for biological cell disruption for DNA/RNA and protein extraction. Long processing times up to 99 hours make the MM 400 ideally suited for research applications, for example in mechanochemistry.

Technical Notes

All buttons are responsive. Lid safety switch works. Display clear. Tested from the lowest frequency to highest frequency. Works as intended.

The original housing for the unit was broken so we replaced it with a housing from a MM200 unit, hence the marking. However, the unit has all MM400 internal parts

Important: Transport screws installed for transport. Remove before use!

Defects

The plastic housing is secured to the base plate through 4 bolts, and the nuts for the bolts are embedded in the plastic housing. On this housing, the part where the two front nuts are embedded is broken, so the front part of the housing cannot be secured to the base plate. The housing is secured with the two rear bolts only. The defect does not appear to affect the functionality of the unit.
