ABSTRACT:
The present invention provides centrifugal rotors for delivering a liquid, typically a biological sample such as diluted plasma, to an unvented chamber in the rotor through an unmodified inlet channel. The unvented chamber is typically a cuvette comprising reagents necessary for analysis of a biological sample. The unmodified inlet channels are sized such that, as the rotor spins, gas escapes from the chamber through the inlet channel as the liquid enters the chamber through the inlet channel. The primary feature which allows the air to escape from the unvented chamber is that the cross sectional area of the inlet channel is greater than the cross sectional area of the liquid flowing through it.
