Flow immunoassay assembly with rotary valve

A flow immunoassay assembly for testing a sample, comprising:

• a plurality of sample distribution chambers configured for containing said sample;
• a plurality of buffer chambers containing buffer;
• a plurality of immunoassay reaction chambers;
• a stator comprising a plurality of entry dispense ports in fluid communication with said plurality of sample distribution chambers, a plurality of auxiliary entry dispense ports in fluid communication with said plurality of buffer chambers, and a plurality of exit dispense ports in fluid communication with said plurality of immunoassay reaction chambers;
• and
• a rotor disposed within said stator and being clockable between a dispense configuration and a first auxiliary dispense configuration, said rotor comprising a plurality of dispense channels connected between said plurality of entry dispense ports and said plurality of exit dispense ports when said rotor is clocked in said dispense configuration, and a first plurality of auxiliary dispense channels connected between said plurality of auxiliary entry dispense ports and said plurality of exit dispense ports when said rotor is clocked in said first auxiliary dispense configuration.

A method of controlling the flow of a sample within a flow immunoassay assembly comprising a rotary valve, a plurality of sample distribution chambers containing said sample, a plurality of buffer chambers containing buffer, and plurality of immunoassay reaction chambers operably connected to said rotary valve, the method comprising:

• placing said rotary valve in a first auxiliary dispense configuration;
• flowing said buffer from said plurality of buffer chambers through said plurality of immunoassay reaction chambers while said rotary valve is in said first auxiliary dispense configuration;
• placing said rotary valve in a dispense configuration;
• and
• flowing said sample from said plurality of sample distribution chambers through said plurality of immunoassay reaction chambers while said rotary valve is in said dispense configuration.

A flow immunoassay assembly, comprising:

• a plurality of sample distribution chambers configured for containing said sample;
• a plurality of immunoassay reaction chambers;
• a stator comprising a feed port, a plurality of distribution port pairs in fluid communication with said plurality of sample distribution chambers, each of said distribution port pairs comprising an entry distribution port and an exit distribution port, and a plurality of exit dispense ports in fluid communication with said plurality of immunoassay reaction chambers;
• and
• a rotor disposed within said stator and being clockable in a distribution configuration, said rotor comprising a feed channel connecting said feed port to an entry distribution port of a first distribution port pair, and a plurality of distribution channels connecting an exit distribution port of each previous distribution port pair to an entry distribution port of each next distribution port pair when said rotor is clocked in said distribution configuration.

A flow immunoassay assembly, comprising:

• a plurality of sample distribution chambers;
• a plurality of buffer chambers;
• a plurality of immunoassay reaction chambers;
• a rotary valve clockable in dispense configuration to place said plurality of sample distribution chambers in fluid communication with said plurality of immunoassay reaction chambers, and clockable in a different auxiliary dispense configuration to place said plurality of buffer chambers in fluid communication with said plurality of immunoassay reaction chambers.
