Abstract
A reagent dispensing valve particularly adapted for dispensing precise microfluidic quantities of fluids. The valve includes a valve portion and a solenoid actuator that are in fluid isolation from one another. The valve portion includes a plunger and seat combination and the actuator is substantially decoupled from the fluid path through the valve. The fluid path through the valve is substantially non-tortuous, thereby minimizing localized fluid pressure drops, and hence undesirable gaseous bubble precipitation within the fluid. The valve is also configured to substantially prevent bubble accumulation. The valve can further include a bubble trap for trapping and removing bubbles.
