Bead beater cell lysis compared to rotor stator homogenizers

False Mechanical homogenizers are more than capable of providing the same level of cell lysis in a fraction of the time it takes a bead mill Most mechanical homogenizing is done in a matter of seconds with ZERO heat produced and you can continue on with your same tubes you are processing in, no need to buy special tubes and beads!

Mechanical Disruption Methods: Beating

The stroke length of the amalgamator or mixer mill is also critical, as is the physical motion it imparts on the sample tube Finally, sample mass, volume, and extraction buffer all impact the effectiveness of the homogenization Tubes/Plates: The objective of bead beating is to sandwich a sample between a grinding bead, or ball, and a hard surface That hard surface can be either another bead
