    MicroCNX® Series Connector

    See MicroCNX® Series Connector Products

    Building on the inventiveness of CPC, the leader in single-use connection technology, the MicroCNX® line introduces a new category of aseptic micro-connectors that provide a simple, efficient method of connecting tubing for small format biomanufacturing assemblies. Process engineers and operators specify MicroCNX sterile micro-connectors as the modern alternative to the cumbersome, industrial process of tube welding. The MicroCNX line is engineered specifically for the challenging conditions of biologic media transfer in bioprocessing, cell therapy and gene therapy applications.

    Specifications & CV Value

    Operating Conditions (Fluid Transfer)

    Pressure: Up to 60 psi, 4.1 bar
    Up to 75 psi, 5.1 bar for 48 hours
    Temperature: 34°F to 104°F (1°C to 40°C)


    Main Components: Polycarbonate (white), USP Class VI, ADCF
    Seals: Silicone (clear), platinum-cured, USP Class VI, ADCF
    Protective Cover: Polypropylene (teal), USP Class VI, ADCF
    Membrane Hydrophobic Polyethersulfone (clear), USP Class VI, ADCF


    Gamma Up to 50 kGy irradiation
    Autoclave One Cycle up to 266°F (130°C) for 60 minutes

    Cv Value (Typical Flow Rate)

    Cv Value Range: 0.04-0.27 for MicroCNX hose barb terminations
    Cv values represent the approximate expected flow rate in gallons per minute of water at room temperature for a 1 PSI pressure drop. The flow is generally constrained by the smallest diameter, which in some cases will be the termination diameter and not the Nominal Flow Path.
    WARNING: Pressure, temperature, chemicals and operating environment can affect the performance of couplings. It is the customer’s responsibility to test the suitability of Colder products in their own application conditions. Use the graph above as a guide.
