2. the utility model can increase the length of practical catheter in identical height so that no by the way that spiral tube is arranged
Equal with the corresponding length of pipe of liquid storage bottle, i.e., the sum of different groups of pipette and drain length of tube are equal, and doing so can make
Depression generator work when, the pressure change in different pipelines is equal, ensures that the corresponding liquid storage bottle liquid of different pipelines takes
Sample efficiency is identical, avoids the corresponding liquid storage bottle of pipeline by approximately level from first collecting full, when other liquid storage bottles regather, leans on approximately level
Pipeline in sampling liquid enter negative pressure device.
3. the utility model makes same height water layer generate swirling flow imbibition, reduces different by setting pipette to arc
Height water layer mobility avoids levels liquid when sampling from mixing seriously, is conducive to uniform sampling.
