The precision manufacturing process requires each capillary cell to be either single piece fabrications or assembled by direct fusion without the use of adhesives. This ensures resistance to chemical attack and extremes of temperature. If direct fusion is required, two pieces are fused together seamlessly. The process begins by machining the material into the appropriate configuration for the application then using heat, time, and pressure a single piece is formed with a bond strength that is near the parent-materialís strength. The bonding process allows for geometries that would be difficult, if not impossible. If required, external machining completes the cell by adding ports and mounting holes. Microfluidic devices typically have features and channel sizes as small as 100 microns while larger fluidic devices have channel sizes ranging from 0.5mm to 3mm. Full round channels offer the best flow characteristics with minimum particle entrapment. Alternative square and D shaped channels are available. Feature spacing can be as low as 0.5mm. Fluidic pressure specifications are design dependent and have successfully performed at greater than 500 psi in the channels.
