Liquid path system based on unit metering and use method thereof

摘要: The invention aims at providing a liquid path system based on unit metering and use method thereof. has the functions of fetching liquid, mixing discharging same time, guarantees accurate is convenient to use. In order achieve effects, comprises an upper solenoid valve, reaction container, lower level sensor, multi-position three-way valve peristaltic pump. Through structure, following benefits as follows: volume mode extraction achieved through hard plastic guide pipe connected between public hole sensor; whole only makes one reagent metered directly enter container be subjected processes mixing, reacting, testing like.
