1. An apparatus for quantitatively treating a liquid, comprising:
a container, the container being used for containing a liquid to be extracted; and
a micro tubule, the micro tubule comprising:
a flow passage, the flow passage extending outwards from the interior of the container to a bifurcation point;
a first by-pass, the first by-pass communicating with the flow passage and extending from the bifurcation point to a first port; and
a second by-pass, the second by-pass communicating with the flow passage and extending from the bifurcation point to a second port;
wherein a first peristaltic pump is disposed in series in at least one of the flow passage, the first by-pass and the second by-pass, and a first cut-off valve or a second peristaltic pump is disposed in series in at least another of the flow passage, the first by-pass and the second by-pass, so that a predetermined volume of liquid between the bifurcation point and the first port or the second port is intercepted, wherein the micro tubule has a pore diameter ranging from 0.05 mm to 5 mm, preferably from 0.1 mm to 3 mm, more preferably from 0.5 mm to 2 mm;
wherein the container is a closed container which does not communicate with the atmosphere, the closed container is connected with a pressurization apparatus for increasing the air pressure in the container, and the flow passage extends outwards out of the container from the interior of the container.
