Abstract

A centrifugal rotor device includes a first chamber configured to hold a fluid, and a second chamber configured to receive the fluid from the first chamber. The centrifugal rotor device also includes a conduit coupled to the first chamber at a conduit inlet and coupled to the second chamber at a conduit outlet, the conduit configured to permit movement of the fluid from the first chamber to the second chamber. The conduit includes a first channel and a second channel formed adjacent to the first channel. The second channel is in fluid communication with the first channel and has a dimension smaller than the smallest dimension of the first channel. The conduit also includes one or more obstructive features present in the second channel configured to impede movement of the fluid in the second channel.
