For 1cm, length 5cm；Diameter and length can make the appropriate adjustments according to graduated cylinder volume.
Preferably, the middle position of communicating pipe described in the utility model is provided with a diameter of 1cm solid valve switch；
For opening and closing valve.
Preferably, valve centre position described in the utility model is provided with a diameter of 0.3cm's perpendicular to valve body direction
Valve hole；The liquid communication in two graduated cylinders can be made by changeover valve, two graduated cylinders of regulation when opening valve are played and measured
The liquid volume taken is completely the same, the effect of the flowing of two amount liquid within the cartridge of barrier when closing valve.
Preferably, valve described in the utility model and its contact surface are frosting.
The utility model compared with prior art, has advantages below and effect：1st, have it is simple and reasonable, cost is low
The characteristics of honest and clean, easy to use, there is popularization and practical value well；2nd, it can simultaneously measure and be separately added into two simultaneously and put down
Purpose in capable sample, speed and the degree of accuracy of experiment can be improved；3rd, parallel to the progress such as reaction speed, reaction temperature
During test, it is possible to reduce error, improve the accuracy of test.
