Description
Technical field
The utility model relates to a kind of ultrafiltration test tube Suction filtration device, belongs to scientific experiment Instrument technology field.
Background technology
In laboratory operation, ultrafiltration test tube is all generally utilize centrifuge to realize its object.Carry out operation with centrifuge to ultrafiltration test tube and there are some drawbacks, on the one hand, it is difficult to realize the precise controlling to filtering, and on the other hand, the test tube hole of Design of Centrifuge is generally less, when processing sample batches, just seems unable to do what one wishes, and speed is slow, and efficiency is low.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of ultrafiltration test tube Suction filtration device, can realize the precise controlling to filtering, and when processing sample batches, can improve speed and efficiency.
The utility model takes following technical scheme to realize above-mentioned technical purpose: a kind of ultrafiltration test tube Suction filtration device, mainly comprise seal box, sealing box cover and vavuum pump, it is characterized in that, it also comprises suction filtration test tube sleeve, air filter unit, 8 townhouse cappings, described sealing box cover coordinates with seal box, its cooperation place arranges sealing ring, described sealing box cover arranges test tube hole array, each test tube hole all arranges sealing the margin, described have the test tube hole of sealing the margin and the major diameter fit of suction filtration test tube sleeve, the internal diameter of suction filtration test tube sleeve and the external diameter of ultrafiltration test tube are sealed and matched, the sidewall of described suction filtration test tube sleeve arranges a passage, the sidewall of described seal box arranges a tubulose air exhaust nozzle, this air exhaust nozzle communicates with in seal box, this air exhaust nozzle connects air filter unit and vavuum pump successively by flexible pipe.The test tube hole array that described sealing box cover is arranged is 12 × 8 arrays, is equipped with the 8 townhouse cappings with sealing effect for test tube hole array.
The beneficial effect of the ultrafiltration test tube Suction filtration device that the utility model provides is, owing to adopting the test tube hole Array Design of 12 × 8 arrays, process sample batches is very convenient; Owing to adopting negative pressure leaching, can be finely controlled suction filtration process by controlled pressure difference; Accept filter liquor owing to being provided with suction filtration test tube sleeve, filtered simultaneously by air filter unit to gas bleeding, avoid and pollute and infect, this is particularly important to some Bioexperiment.
Accompanying drawing explanation
Fig. 1 is the external structure schematic diagram of seal box of the present utility model and lid etc. thereof, and Fig. 2 is the internal structure sectional view of seal box of the present utility model and lid etc. thereof, and Fig. 3 is the connection diagram of the utility model ultrafiltration test tube Suction filtration device total system.
In figure, 1, seal box, 2, sealing box cover, 3, test tube hole, 4, suction filtration test tube sleeve, 5, ultrafiltration test tube, 6, passage, 7,8 townhouse cappings, 8, air exhaust nozzle, 9, flexible pipe, 10, air filter unit, 11, vavuum pump.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of ultrafiltration test tube Suction filtration device, comprise seal box 1, sealing box cover 2, vavuum pump 11, suction filtration test tube sleeve 4, air filter unit 10 and 8 townhouse capping 7 etc., described sealing box cover 2 coordinates with seal box 1, its cooperation place arranges sealing ring, described sealing box cover 2 arranges test tube hole 3 array, each test tube hole 3 all arranges sealing the margin, described have the test tube hole 3 of sealing the margin and the major diameter fit of suction filtration test tube sleeve 4, the internal diameter of suction filtration test tube sleeve 4 and the external diameter of ultrafiltration test tube 5 are sealed and matched, the sidewall of described suction filtration test tube sleeve 4 arranges a passage 6, the sidewall of described seal box 1 arranges a tubulose air exhaust nozzle 8, this air exhaust nozzle 8 communicates with in seal box 1, this air exhaust nozzle 8 connects air filter unit 10 and vavuum pump 11 successively by flexible pipe 9.Test tube hole 3 array that described sealing box cover 2 is arranged is 12 × 8 arrays, is equipped with the 8 townhouse cappings 7 with sealing effect for test tube hole array.
When this ultrafiltration test tube Suction filtration device uses, first sealing box cover is buckled on seal box, air filter unit and vavuum pump is connected with flexible pipe, ultrafiltration test tube to be filtered is inserted in suction filtration test tube sleeve, be less than test tube hole sum (12 × 8) as samples, then seal unnecessary test tube hole with 8 townhouse cappings, then the suction filtration test tube sleeve of inserting ultrafiltration test tube is inserted in each test tube hole, open vavuum pump and carry out suction filtration.
