Abstract: A fluid transportation system and method use a negative pressure driving mode to absorb fluids from a fluid storage assembly and a positive pressure driving mode to load the absorbed fluids into the fluid-using system. At least two working modules are used to transport fluids to the fluid-using system, the process of transporting fluid in each working module being divided into the processes of absorbing fluids into a fluid transfer assembly, and loading fluids into a fluid transfer assembly. The process of absorbing fluids in each working module and the processes of absorbing fluids and/or loading fluids in any other working module overlap at least partially along the time axis. With the present disclosure, the accuracy and speed of fluids transportation are improved, a device utilizing the system and method is also disclosed.

Abstract: A biochemical substance analysis system (5) is used to detect biological characteristics of a sample in a flow cell (38), and includes a detection system (51), a scheduling system (53), a biochemical reaction system (55), and a control system (57). The scheduling system (53) is used to schedule the flow cell (38) at different sites, including sites in the detection system (51) and sites in the biochemical reaction system (55). The biochemical reaction system (55) is used to allow the sample to react in the flow cell (38). The detection system (51) is used to detect a signal from the reacted sample to obtain a signal representing the biological characteristics of the sample. The control system (57) is used to control the detection system (51), the scheduling system (53), and the biochemical reaction system (55) to cooperate. The disclosure improves automation degree and flux of the biochemical substance analysis.

Abstract: A flow path system, a gene sequencer and a reagent recovery method. The flow path system comprising at least two reagent storage containers, a flow cell, a shunting module and a fluid power unit. The flow cell is connected to the at least two reagent storage containers. The shunting module comprises a shunt structure and at least two shunt channels. The fluid power unit is connected to the shunting module, the fluid power unit is selectively connected to one of the at least two shunt channels, and the fluid power unit is configured to drive a forward flow of the reagent from the reagent storage container toward the shunting module, and the fluid power unit is further configured to drive a reverse flow of the reagent from the shunting module toward the reagent storage container.
