Abstract: A syringe system (100) is provided. The syringe system comprises a pump assembly (101) including a movable actuation rod (440) and a plunger contact (445) coupled to an end of the movable actuation rod (440). The syringe system also comprises a cartridge assembly (102). The cartridge assembly (102) includes a manifold (105) removably coupled to the pump assembly (101) and a syringe cartridge (107) positioned within the manifold (105) and including a plunger assembly (330) movable with respect to the manifold (105) upon actuation of the actuation rod (440).

Abstract: A rear feed solenoid-operated valve design is particularly suited for micro-fluidic applications. The solenoid valve contains various structures and features that provide for small dispense volumes, small internal volume, and fast operating speed. The valve includes an inlet, outlet, coil housing, magnetic plunger rod and a diaphragm assembly. In a preferred embodiment, the diaphragm assembly ensures zero leakage. The solenoid-operated valve further has features allowing for low power consumption. The valve is placed at a desired location by a positioning mechanism located at the rear end of the valve. The positioning mechanism feeds fluid through the inlet and dispenses the fluid at the outlet located at the front, or bottom of the valve.

Abstract: A solenoid operated valve includes a fluid inlet and a fluid inlet, a common port, a normally open port and a normally closed port combined on an end cap. The valve further includes a coil housing that houses two coils, a first coil and second coil, that are in parallel with each other creating two parallel longitudinal axes for a normally open assembly and a normally closed assembly. The normally open assembly includes a first diaphragm assembly, a plunger rod having barbed ribs on a proximal end thereof, a magnetic pin and a body that is coupled to a distal end of the plunger rod. The normally closed assembly includes a second diaphragm assembly, a plunger and a magnetic post. The first and second coils are simultaneously actuated.

Abstract: A solenoid-operated valve design and method particularly for suited for micro-fluidic applications are disclosed. The solenoid valve contains various structure and features that provide for small dispense volumes, small internal volume, and fast operating speed. Also disclosed is a valve design and method particularly suited for a compact, high-density valve manifold. In a particular embodiment disclosed, the valve uses a diaphragm assembly that ensures zero or little leakage. The solenoid-operated valve further has features allowing for low power consumption.
