ABSTRACT:
The present invention provides centrifugal rotors for delivering a liquid, typically a biological sample such as diluted plasma, to a plurality of cuvettes in the rotor. The cuvettes are positioned radially inward of an annulate manifold and are connected to the manifold through a plurality of inlet channels. The liquid is introduced in one end of the manifold and, as the rotor spins, the liquid fills the manifold from the radially outward edge inward. After, the manifold fills, the liquid flows radially inward through the inlet channels into the chambers. The design allows the simultaneous filling of the cuvettes. The inlet channels may also be sized such that as liquid enters the cuvettes, gas escapes through the inlet channel.
