Material compatibility
Confirm solvent, analyte, adsorption, leachables, sterilization, and temperature requirements.
Tubing selection
Microfluidic tubing for controlled research flow
Compare PTFE, FEP, PEEK, silicone, Tygon, and microbore tubing for microfluidic systems by material, dimensions, flexibility, and application.
Selection answer
How should you choose?
Choose microfluidic tubing by material compatibility first, then confirm inner diameter, outer diameter, pressure, bend radius, connection method, and required length. PTFE supports broad chemical resistance, FEP adds optical clarity and flexibility, PEEK is used for rigid high-performance fluid paths, and silicone suits compliant or peristaltic-pump sections.

Confirm the complete system requirement
MicroCD Labs reviews compatibility, documentation, final pricing, availability, and lead time before payment.
ID and OD
Inner diameter influences resistance and internal volume; outer diameter must match the connector.
System behavior
Consider pressure, flexibility, pulsation, permeability, and whether the line enters a pump head.
