Side is closely sealed with interface in the first hermetic bag；And
Metal foil seal housing another side is provided with the second valve, and the joint of the second valve passes through metal foil seal housing
Side it is closely sealed with interface in the second hermetic bag.
Relative to single bag of single head sampler bag of prior art, the micro-control sampler bag of the present invention has the following technical effect that：
(1) micro-control sampler bag of the invention adopts two hermetic bags, a certain amount of by being passed through in a hermetic bag thereto
Cheap gas (for example, air) or liquid (for example, water), while the body such as discharging from another hermetic bag by mutually extruding
The sample of product collection is easy to operate being detected, it is easy to which sample is discharged on controllable precise ground, stability of flow ground.
(2) micro-control sampler bag of the invention need not add the pipelines such as effusion meter in sample outlet, can easily discharge
Liquid, gaseous sample, the micro-control sampler bag simple structure, cost is relatively low, and can repeatedly reclaim and use.
(3) micro-control sampler bag of the invention is particularly well-suited to the analysis of a small amount of gaseous sample, it is to avoid manual squeezing sampling
Instability of flow and a large amount of problems for wasting sample when bag discharges sample.
(4) for harmful sample, because the micro-control sampler bag of the present invention can accurately, quantitatively discharge sample, so as to not
Occur the phenomenon of " being directly discharged to human and environment be worked the mischief in air by substantial amounts of redundance ".
(5) micro-control sampler bag of the invention adopts two hermetic bags, each of which to have independent interface and valve, it is ensured that two
Sample in bag is completely independent and will not mutually pollute.
(6) micro-control sampler bag of the invention is particularly suited for gaseous sample, can accurately, quantitatively, stably discharge gas
Sample.
