ABSTRACT:
Disclosed is to a device for exchanging minimum amount of the fluid only by using surface tension of the fluid instead of external force like a pump. According to the device, an additional pump and power supply is not needed, thereby the device can be small sized and portable, and not only manufacturing cost decreases and yield increases but the device is hardly out of order.
