Life And Warranty Of Rotor - Thermo Scientific TCF-32 Instruction Manual

7. LIFE AND WARRANTY OF ROTOR

While using rotor repeatedly, its strength decreases g radually due to fatigue and creep of
material, by which the rotor life is determined. Sum up the number of operations and number of
operating hours, and if e ither value reaches the figures (the primary life) shown in Table 8,
decrease the maximum speed of the rotor by 10%.
If the operations or operating hours of rotor reach the figures in Table 8 after decreasing the
maximum speed by 10% (Secondary life), don't use the rotor any more.
This specification is applied to the rotor body assembly. Shaft (D) and the seal are consumable
parts.
