Can be used up to 50,000xg in refrigerated and non-refrigerated centrifuges must be filled to 80% of the total capacity. With sealing cap closure option. Before autoclaving, just set closure on top of the tube without engaging the threads. All centrifuge ware must be filled to 80% of total capacity for proper performance unless otherwise noted.
