Features

• A PDMS chip incorporating a peristaltic pumping function, whereby rollers rotate and compress a Ω-shaped channel to directly pump the liquid inside. The PDMS chip is replaceable and sterilizable.
• Pulsations, which are the drawbacks of conventional peristaltic pumps, are greatly reduced to the level acceptable for a flow cytometer or a cell sorter. See the red line of the graph below.
• This is a conceptual model of a disposable flow cytometer, in which a sample flow pump, two sheath flow pumps, and a flow cell are incorporated onto one chip. This can be easily replaced for each fluid.
