Description
Technical Field

The flow cell is used as a reaction chamber, and a fluid system designed to serve the flow cell is needed for transporting samples, reagents, water, cleaning agents or fluids with other functions into the flow cell, and meanwhile, the fluids used in the flow cell can be transported to a waste liquid container to be discarded or transported to other containers for recycling.
In the prior art, the classic design is a direct flush fluid system. This design requires only a common section of piping before the inlet of the flow cell for the inflow of all kinds of fluids. When a plurality of different fluids are used in the flow cell, the valves or the combination of the valves can be used to connect the pipes for connecting the different fluids with the common pipe respectively, and then the power module is used to drive the fluids into the flow cell through the valves and the common pipe.
A first problem with this design is the waste associated with fluid replacement. The flow rate required for the replacement of the fluid in the common conduit and the flow cell is proportional to the inner volume of the flow space, and only the fluid eventually filled in the flow cell is effectively used, whereas part of the fluid previously consumed for the replacement of the common conduit and the flow cell is wasted. A second problem is the restriction of the flow cell to the use of fluid. During use of the flow cell, other lines cannot be cleaned, and thus cannot be prepared for the next fluid to be flowed into the flow cell, resulting in poor flexibility in fluid delivery.
Therefore, a fluid system is needed to address the above-mentioned problems.
