PUMP AND LIQUID SUPPLY METHOD

摘要

Provided is a pump capable of achieving a flow volume sufficient for use in an analysis system in a microenvironment. In this pump a valve (4) oscillates with a distance of 150-300μm between a central position (the position midway between the position where the other end of the valve is farthest from a constriction part (3) and the position where the other end of the valve is closest to the constriction part) and the end of the constriction part closer to the valve.
