Bead Beating A PrimerOPS Diagnostics LLC
Bead beating is an effective mechanical method used to disrupt a wide range of biological samples. At a minimum bead beating is accomplished by rapidly agitating a sample with grinding media (beads or balls) in a bead beater (device that shakes the homogenization vessel). Selected raw materials were wet batch milled with the use of a Netzsch LME 1 horizontal bead mill under air atmosphere. The milling chamber (1.225 L) was loaded to a capacity of 60 (by volume) with 2 mm diameter yttrium stabilised zirconia beads. Cooling water was allowed to circulate through
