Fluid flow splitting device for microfluidic applications

A microfluidic flow splitting device comprising:

• a substrate;
• an inlet channel formed in the substrate, the inlet channel coupleable to a supply tube providing a sample fluid, the inlet channel including a height that is less than an inner diameter of the supply tube;
• a plurality of outlet channels formed in the substrate, the plurality of outlet channels coupleable to and in fluid communication with a downstream microfluidic device;
• and
• a junction formed in the substrate, the junction in fluid communication with the inlet channel and the plurality of outlet channels;
• wherein the sample fluid is provided to the inlet channel at a volumetric flow rate up to 3 ml/min, and
• wherein each of the plurality of outlet channels is configured to provide a portion of the sample fluid to a respective downstream microfluidic device at a volumetric flow rate between 0.01 to 3 ml/min with less than an 8% coefficient of variation between the outlet channels.
