Fluidic System
2.3 Composition of Fluidic System
The fluidic system consists of the following subsystems: sensor subsystem, bath
subsystem, lyse dispensing and mixing subsystem, diluting subsystem,
volumetric metering subsystem, vacuum subsystem, pressure subsystem and
auxiliary subsystem.
The key components of the fluidic system are the solenoid valve, syringe,
aperture, sample probe, pump, bath ， metering tube, probe module,
negative/positive pressure chamber and hose.
The solenoid valve is ASCO458. Totally 11 valves are used, 7 three-way valves
and 4 two-way valves.
The two syringes, 10mL and 50uL, are made by Mindray.
The aperture is Ø80.
The sample probe has two layers and its surface is polished, making the probe
easy to clean.
