3.1.2 Tube kinetics
Given the design and symmetry of the machine, each of the tubes of
the same type placed in the rack has strictly the same kinetics, which
guarantees the same quality of lysis and homogenization in each of the
tubes.
The centre of gravity of the tubes moves through a complex hemispherical-
shaped pathway. The mixture contained in the tubes therefore undergoes
a three-dimensional motion that prioritizes vertical movements, thereby
ensuring the efficiency of the lysis. The movement generated by the
PRECELLYS® Evolution Touch is a precessional motion, which means that
the tubes are not rotated.
The geometry of the tubes used must be compatible with the rack and be
able to withstand accelerations of 600 g for 5 minutes without becoming
deformed (see recommendations for use § 2.6.1).
The precessional motion undergone by the biological samples causes the
temperature of the sample and apparatus to rise.
