    In organ-on-a-chip (OOC) processes, a cell culture membrane is placed in between two resealable glass slides to form two separate flow chambers. This allows two different flows, of either liquids or gases, on either side of the membrane. This dynamic microfluidic flow approach enables new and innovative ways to culture cells and tissues while offering precise and continuous control during the complete culturing process. The membrane layer together with a top and bottom OOC layer makes an organ-on-a-chip resealable flow cell.

    The details of this layer are:

    The pores are created using track-etching and have a random orientation:

    Customer Questions
    Is it possible to monitor oxygen levels?
    It is possible to couple Micronit OOC devices to commercial optical readers for dissolved gases in the culture medium. This option allows for applications such as the monitoring of oxygen in the culture chamber.
    Is my OOC system compatible with my imaging systems?

    The membrane is moving and flow is switching between top and bottom flow path. What is happening?
    Always check that there’s no blockage in one of the flow paths, this can be verified by checking the amount of collected liquid in a specific time frame and compare it with the expected amount for the flow rate used.If this isn't the case, droplet formation on the end of the tubing is the problem. Each falling droplet affects the flow a bit, resulting in changes in flow rates. Resolve this by keeping the end of the tubing in the collection reservoir submerged in liquid.
    How do I clean my resealable flow cell's / OOC top and bottom layers?
    The glass layer without a gasket can be cleaned using the same methods commonly used for glass microscope slides. The gasket layer, however, requires more careful handling. For detailed instructions, see "Read More".

    What pump system should I use for a resealable flow cell or OOC chips?
    It's important that the pressure system can limit the amount of pressure that will be applied. We would recommend a pressure based system. However it should be possible to use a syringe pump when a pressure relief valve is applied for each liquid path.
