3.1 Rotor body assembly
(1) Rotor and cover
The rotor and cover are made of titanium alloy which is excellent in mechanical strength
and corrosion resistance, and is coated in black (see Fig.2)
(2) Core titanium sleeve and blades
All of them are introduced in the rotor. The core forms a passage of sample and density
gradient solution in the rotor. Its material is Noryl.
The titanium sleeve is for reinforcing the core, and is put on the outside of the core. It is
made of titanium alloy.
The blades are for preventing the sample and density gradient solution in the rotor from
whirling up. It is made of Noryl.
