Description
Technical field
The sample purification equipment in the residual detection of agriculture is the utility model is related to, is specifically a kind of disposable purification pipe.
Background technology
At present, known purification pipe is that purification thing is added in plastic centrifuge tube, after sample solvent extraction, will be extracted
Liquid is added in purification pipe, is closed the lid, and after being well mixed on eddy mixer, purification pipe is put into centrifuge, after centrifugation
Take supernatant liquor bottling detection.Whole process process is more, than time-consuming, and when sample is more, operates whirlpool for a long time
Blender meeting opponent causes employment injuries.
Utility model content
For above-mentioned weak point of the prior art, the utility model aim to provide it is a kind of it is easy to use, shorten it is net
Change flow, save the clarification time and prevent operating personnel long-time operation eddy mixer opponent from causing the disposable of employment injuries
Purification pipe.
In order to solve the above technical problems, a kind of disposable purification pipe of the present utility model, including formed using plastic production
The first centrifuge tube and the second centrifuge tube, using being threadedly coupled between first centrifuge tube and the second centrifuge tube, described first
Be provided with external screw thread on centrifuge tube, the upper end of first centrifuge tube is provided with the vinyl cover with rubber cushion, the external screw thread with
The vinyl cover connection, the lower end of first centrifuge tube is provided with filter membrane, drying layer is provided with the filter membrane, described
Purifying layer is provided with drying layer.
Preferably, O-ring seal is provided between first centrifuge tube and the second centrifuge tube, the O-ring seal is used for
Seal the first centrifuge tube and the second centrifuge tube.
Preferably, the filter membrane is micropore filtering film.
Preferably, it is provided with drier in the drying layer, the drier in the drying layer is anhydrous sodium sulfate.
Preferably, it is provided with cleanser in the purifying layer, the cleanser in the purifying layer is Fo Luoli tripoli.
Preferably, a diameter of 10~15mm of first centrifuge tube, wall thickness are 0.5~1mm, a height of 55~65mm.
Preferably, the bottom of second centrifuge tube is in cone.
Disposable purification pipe of the present utility model has the advantage that：First, all process steps are grouped as by the utility model
It one, can not only simplify purification technique, and save sample processing time, so as to reduce labor intensity, improve production effect
Rate.Second, the time due to reducing purification sample, prevents employment injuries caused by long-time operation eddy mixer opponent.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As shown in figure 1, a kind of disposable purification pipe of the present utility model, including the first centrifugation formed using plastic production
The centrifuge tube 2 of pipe 1 and second, use and be threadedly coupled between first centrifuge tube 1 and the second centrifuge tube 2, first centrifuge tube 1
On be provided with external screw thread 3, the upper end of first centrifuge tube 1 is provided with the vinyl cover 4 with rubber cushion, the external screw thread 3 and institute
Vinyl cover 4 to be stated to connect, the lower end of first centrifuge tube 1 is provided with filter membrane 5, and drying layer 6 is provided with the filter membrane 5,
Purifying layer 7 is provided with the drying layer 6.
Further, O-ring seal 8, the O-ring seal are provided between the centrifuge tube 2 of the first centrifuge tube 1 and second
8 are used to seal the first centrifuge tube 1 and the second centrifuge tube 2.The setting of O-ring seal 8, play a part of preventing solvent from flowing out.
Further, the filter membrane 5 is micropore filtering film.
Further, it is provided with drier in the drying layer 6, the drier in the drying layer 6 is anhydrous sodium sulfate.
Described anhydrous sodium sulfate be by 500 DEG C of anhydrous sodium sulfates for burning 4 hours (if solvent is water, cancelling this layer),
The anhydrous sodium sulfate added plays a part of to solvent dehydration.
Further, it is provided with cleanser in the purifying layer 7, the cleanser in the purifying layer 7 is Fo Luoli tripoli.
Further, a diameter of 10~15mm of first centrifuge tube 1, wall thickness are 0.5~1mm, a height of 55~65mm.
Further, the bottom of second centrifuge tube 2 is in cone.
Specifically, in use, opening vinyl cover 4, the solvent after extraction is poured into the space of the first centrifuge tube 1, covered
Vinyl cover 4, is tightened；Then the utility model is put into centrifuge on 15mL shelf, shuts centrifuge, start centrifugation (such as
It is required that rotating speed is higher, wall of the present utility model can be thickeied and the conical bottom of the second centrifuge tube 2 is made into circular base).After centrifugation,
The utility model is taken out, opens the second centrifuge tube 2, solvent directly or after concentration constant volume is poured into sealing in sample injection bottle.
Obviously, described embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belong to the scope of the utility model protection.
