Claims
- 1. A flow cell comprising:
an endless loop manifold, the endless loop manifold including a plurality of inlet channels, each of the inlet channels connectable with a reservoir and controllable by a valve, the inlet channels end in an inlet chamber, the inlet chamber having an outlet channel at each of opposing ends of the inlet chamber, the outlet channels dividing a fluid flow around a closed loop and recombining the fluid flow at an at least one common discharge channel.
- 2. The flow cell according to claim 1, wherein the closed loop is formed by a restriction element disposed between the inlet channels and the discharge channel.
- 3. The flow cell according to claim 2, wherein the restriction element delineates the closed loop and is bounded on opposing sides by the outlet channels.
- 4. The flow cell according to claim 1, wherein the inlet channels and at least a portion of the outlet channels are arranged generally parallel to the discharge channel.
- 5. The flow cell according to claim 1, wherein the inlet chamber has a length which is arranged generally perpendicular to the inlet channels and the discharge channel.
- 6. The flow cell according to claim 1, wherein the endless loop manifold further comprises a restriction element bounded on one side by the inlet chamber, the restriction element being surrounded by the outlet channels on at least three sides, and the endless loop manifold discharging fluid into the discharge channel on a side opposite the inlet chamber.
- 7. The flow cell according to claim 1, wherein the endless loop manifold facilitates removal of old fluid from the flow cell by displacing an entire volume of old fluid with a volume of new fluid, the old fluid flows through the outlet channels and the discharge channel out of the flow cell leaving new fluid in the flow cell.
