Suction filtration device be to be taken out the sucking filtration end of filter as negative pressure with vacuum pump, using the carrying out with the pressure reduction accelerated filtration of air.
Sucking filtration substantially increases filtration separation efficiency, is widely used in biology, physics and chemical experiment.Traditional laboratory is taken out
Filter device is to clamp liquid storage bucket with alligator clamp with filtering head, and liquid-collecting bottle and filtering head are realized close by specific frosted interface
Envelope.But in actual mechanical process, need bimanualness using alligator clamp clamping liquid storage bucket with filtering head, accidentally hold in operating process
Easily make liquid storage bucket drop to break into pieces；Liquid-collecting bottle be special-purpose bottle, other bottles due to bottleneck and filtering head are incompatible cannot be general, in mistake
Filter and can only use same liquid-collecting bottle during all solution, so needing to carry out multiple rinse to liquid-collecting bottle when changing filtrate, many
Secondary repetition evacuation, rinse, the operation of emptying, process is loaded down with trivial details and easily causes pollution；Because liquid-collecting bottle passes through mill with filtering head
Sand mouth connects, and usually the phenomenon that airtight tension is difficult to open during sucking filtration；It is liquid chromatogram mobile phase in filtrate
When, mobile phase also need to after transferring in mobile phase bottle ultrasonic be exhausted, have a strong impact on conventional efficient.
For overcoming disadvantage mentioned above, the present invention proposes the type of attachment of a kind of new liquid storage bucket and filtering head, using liquid storage bucket
Self gravitation and after taking out negative pressure atmospheric pressure realize airtight connection, eliminate alligator clamp, one hand can complete, and structure is simpler,
Operate safer convenience；Liquid-collecting bottle adopts international hickey with filtering head interface, can directly outward winding after the completion of sucking filtration,
Avoid a stubborn difficult problem after existing apparatus sucking filtration；Liquid-collecting bottle is directly using reagent bottle or the mobile phase holding filtrate
Bottle, need not rinse repeatedly, simplify operation；Avoid and topple over transfer after filtering liquid chromatogram mobile phase, need not ultrasonic aerofluxuss, carry
High conventional efficient.
