A system includes a reagent selector valve controllable to select a reagent flow path from a plurality of reagent flow paths, and a pump coupled to the reagent flow path to draw a liquid through the reagent flow path in accordance with a prescribed test protocol. The system includes a discharge flow path to expel the drawn liquid, and a flow meter to measure liquid displaced by the pump and that outputs data representative of the measured flow. The system also includes a processor to access the data and to determine a volume of the liquid displaced by the pump.

Automated volumetric reagent delivery testing

An analysis system includes a fluidic system includes a number of components that are interconnected to form a fluidic system having a plurality of flow paths. An example method of pressure testing the fluidic system includes (a) selecting a flow path from the plurality of flow paths through a flow cell in accordance with a prescribed test protocol; (b) actuating a pump to pressurize a fluid in the selected flow path; (c) generating pressure data representative of the pressure in the selected flow path; and (d) processing the pressure data to determine whether the selected flow path maintains pressure in a desired manner.

Pressure and leak testing methods

A system may include a flow cell through which a plurality of reagents may be pumped during a genetic sequencing operation, an effluent line that, in operation, is to conduct a used reagent, a used reagent valve to receive the used reagent from the effluent line and controllable to select one of a plurality of disposal paths for the used reagent, and control circuitry coupled to the used reagent valve that, in operation, is to control the used reagent valve to select a desired one of the disposal paths depending upon which reagent is being pumped though the flow cell.
