are present; In the sampling process of electronic chemical product,, must set up dustless sampling hut usually and perhaps clean sampling cabinet is set at the discharging opening of extractor in order to satisfy requirement to environment cleanliness; Although this sampling mode science, reasonable; But need to drop into very big cost, take more space, and complex operation.In addition, electronic chemical product can overflow in sampling process unavoidably, and these excessive chemicals are not recycled, and must cause unnecessary waste.

, satisfying under the prerequisite that environment cleanliness is required, can sampler a kind of simple in structure, easy to operate is provided be that industry has problem to be solved for this reason

Summary of the invention

The task of the utility model be to provide a kind of simple in structure, easy to operate, use cost is low, space availability ratio is high, can guarantee by the cleanliness factor of sample thief and can reclaim the ultra clean electronic chemical product sampler of sampling process China and foreign countries discharge.

The task of the utility model is accomplished like this; A kind of ultra clean electronic chemical product sampler; Comprise electronic chemical product hold-up vessel body, be used for the discharge nozzle that communicates with the jar chamber of electronic chemical product hold-up vessel body and be located at the discharging operation valve on the discharge nozzle, be characterized in: also comprise PE (polyethylene film) sack, sampling jar and pallet, described sampling jar, pallet all place in the PE sack; And pallet be positioned at sampling jar under; PE sack sack down, in the bag place of penetrating, the end insertion PE sack of the mouth of pipe of discharge nozzle by the PE sack, the mouth of pipe of discharge nozzle extend into the bosom position of sampling jar; Simultaneously, penetrating of the bag end needs clamped sealed between place and the discharge nozzle.

A pipe clamp clamped sealed is passed through between the described bag end and the discharge nozzle in in a specific embodiment of the utility model.

in another specific embodiment of the utility model, described PE sack is ultra clean no static polythene film bag.

in another specific embodiment of the utility model, described sampling jar preferably adopts the sampling jar of soluble poly tetrafluoroethene (PFA) material.

the utility model is because after adopting said structure; The beneficial effect that has: substitute dust free room of the prior art or clean sampling cabinet by the PE sack; Not only cost is low; It is little to take up room, and ultra clean no static PE sack can play dustproof, moistureproof, heat-resisting effect, can guarantee by the cleanliness factor of sample thief; In addition, below sampling jar, be provided with pallet, can collect, so that utilize again the electronic chemical product sample that overflows.
