Abstract
A fluid flow controller for introducing fluids into a microfluidic device is provided. The fluid flow controller comprising, at least one high resistance fluid pathway provided between an inlet port and a connection port; at least one low resistance fluid pathway between the inlet and connection port; and at least one valve configured to enable fluid flow through the high resistance fluid pathway, the low resistance fluid pathway or both.
Claims9
A fluid flow controller for introducing fluids into a microfluidic device, the controller comprising:
- a first resistance fluid pathway provided between an inlet port to the fluid controller and a connection port to the microfluidic device;
- a second resistance fluid pathway between the inlet port and the connection port;
- wherein the resistance of the second resistance fluid pathway is at least 10 times less than the resistance of the first resistance fluid pathway;
- and wherein the controller further comprises at least one valve configured to close the second resistance fluid pathway only.
