ABSTRACT:
A continuous flow type centrifuge to which a liquid sample is continuous supplied. The centrifuge includes a rotor rotatably supported by a main housing and drivingly rotated by a motor. The rotor includes a cylindrical rotor body, a hollow cylindrical core body, and end plates. The hollow cylindrical core body is disposed in the rotor body providing a space therebetween. The core body has an upper open end, a lower open end and an outer peripheral surface provided with a plurality of partitioning walls positioned at an equal interval in a circumferential direction of the core body for providing a plurality of cavities each defined by the core body, the rotor body and neighboring partitioning walls. The end plates include an upper end plate disposed to cover the upper open end, and a lower end plate disposed to cover the lower open end. An upper welding part is disposed at a boundary between the upper end plate and the upper open end, and a lower welding part is disposed at a boundary between the lower plate and the lower open end. The components of the rotor are made from heat resistant and corrosion resistant material, typically titanium or titanium alloy.
