摘要:
Fluidic cartridge including a liquid container having a reservoir configured to hold a liquid. The liquid container includes an interior surface. The fluidic cartridge also includes a transfer tube that extends from the interior surface to a distal end. The distal end includes a fluidic port that is in flow communication with the reservoir through the transfer tube. The transfer tube has a piercing segment that includes the distal end. The fluidic cartridge also includes a movable seal that is engaged to the piercing segment of the transfer tube and configured to slide along the piercing segment from a closed position to a displaced position during a mating operation. The movable seal blocks flow of the liquid through the fluidic port when in the closed position. The piercing segment extends through the movable seal when in the displaced position.
摘要:
Systems and methods for conducting designated reactions that include a fluidic network having a sample channel, a reaction chamber, and a reservoir. The sample channel is in flow communication with a sample port. The system also includes a rotary valve that has a flow channel and is configured to rotate between first and second valve positions. The flow channel fluidically couples the reaction chamber and the sample channel when the rotary valve is in the first valve position and fluidically couples the reservoir and the reaction chamber when the rotary valve is in the second valve position. A pump assembly induces a flow of a biological sample toward the reaction chamber when the rotary valve is in the first valve position and induces a flow of a reaction component from the reservoir toward the reaction chamber when the rotary valve is in the second valve position.
摘要:
A flow cell including inlet and outlet ports in fluid communication with each other through a flow channel that extends therebetween. The flow channel includes a diffuser region and a field region that is located downstream from the diffuser region. The field region of the flow channel directs fluid along reaction sites where desired reactions occur. The fluid flows through the diffuser region in a first flow direction and through the field region in a second flow direction. The first and second flow directions being substantially perpendicular.
