How to Select Suitable Fittings for a Microfluidic System
Fittings affect sealing performance, assembly efficiency, maintenance convenience and long-term stability. Selection should consider tubing size, connection method, pressure, fluid media and installation space.
The role of fittings in fluidic systems
In a microfluidic system, fittings support fluid transfer, sealing and structural connection. Different applications place different requirements on fittings. IVD instruments often focus on long-term stability and batch consistency, while laboratory automation may focus more on assembly and maintenance convenience.
Key factors for selection
Fitting selection starts with tubing outer diameter, inner diameter and interface compatibility. The connection method, such as rigid tubing, flexible tubing, ferrule connection, flanged connection or threaded connection, also needs to be confirmed. Pressure, media compatibility and maintenance conditions should be considered for more demanding systems.
