The utility model enlarges the application range of the conventional laboratory-use centrifuger, expands precipitation separation to filtration separation, overcomes defects in the prior art, and avoids air resistance during centrifugal separation, so that the filtration can be smoother.
Description
Technical field
The utility model belongs to the centrifugal separation equipment technical field, particularly a kind of filter that is used with laboratory centrifuge.
Background technology
The laboratory is centrifugal to fall heavy and filter is that to carry out Physical Chemical Experiment be the separating substances means that arrive commonly used.Its separately principle and characteristics be:
Falling the experiment centrifuge that heavy separation uses usually is that a kind of centrifuge tube that sample solution will be housed places on the centrifuge-head, utilizes rotary head to rotate the powerful centrifugal force that is produced at a high speed around axle, makes solid particulate matter rapid subsidence in the sample solution and separates.Be mainly used in aspects such as medical test, biochemical extraction, plant extract.General separation postprecipitation thing still in solution, in case of necessity, also needs sediment is further separated with solution.
In the laboratory sample preparation, when carrying out Separation of Solid and Liquid, generally all use the method for vacuum filtration.Be the supporting use of Bu Shi leak and bottle,suction, filter cake is stayed in the Buchner funnel during operation, and mother liquor gets into bottle,suction.This method can thoroughly be separated solid-liquid, and is easy to operate, and treating capacity is changeable, but has following defective:
The tiny difficult operation of crystalline particle.
The operation of viscosity of sludge disaster is like massecuite, liquid glucose, Chinese medical extract etc.
To the solution of easy volatile solvent such as ethanol, methyl alcohol, acetone, ether, chloroform etc., because vacuum volatilization, the mother liquid concentration after the filtration is wayward.
Because a large amount of air get into materials during suction filtration, and solvent volatilize under vacuum soon, and material is lowered the temperature obvious, and the moisture that condenses easily is so the material of commute moisture absorption, facile hydrolysis should not use.
The someone adopts centrifuge tube to add the scheme of interior cover at present, realizes centrifugal filtration, to eliminate the defective of vacuum filtration, fast solid-liquid is thoroughly separated.But this scheme is when carrying out centrifugal filtration, and interior cover can tightly be pushed down centrifuge tube, and the air of centrifuge tube bottom is difficult to discharge, and forms vapour lock, causes the not smooth defective of filtration easily.
The utility model content
The technical problem that (one) will solve
The technical problem that the utility model will solve is: overcome the defective of prior art, realize that on laboratory centrifuge centrifugal filtration separates.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of filter that is used with laboratory centrifuge.This filter is made up of filter bag, bracing frame, centrifuge tube; Support frame as described above is placed in the centrifuge tube, and its bottom is a porous plate; Said filter bag is enclosed within the centrifuge tube mouth of pipe, and bag is in the position between centrifuge tube inside bore and the bracing frame bottom.
The described centrifuge tube of the utility model is meant the container of the solution when using centrifuge, comprises centrifuge tube, centrifugal bottle and other suitable containers.
When carrying out separating and filtering, bracing frame plays a supportive role to filter bag; And centrifuge tube is divided into two parts, make the centrifuge tube bottom have enough spaces to store the mother liquor that leaches in the separating and filtering.
The bottom of bracing frame is a porous plate, is convenient to mother liquor and gets into the centrifuge tube bottom smoothly, avoids vapour lock.
Above-mentioned a kind of filter that is used with laboratory centrifuge, the centrifugal mouth of pipe have a dismountable pipe lid.
Pipe is stamped isolating environment sealing and the fixedly effect of filter bag and bracing frame.
Wherein, bracing frame bottom is circular porous plate, top be one with the annulus of centrifuge tube with the internal diameter stack pile, sidepiece is the straight-bars of at least 2 connection porous plates and annulus; Said annulus can frame at the edge of centrifuge tube.
For reducing the corrosion of medium, guarantee that the material that purity of filtering and the service life that prolongs this filter, above-mentioned bracing frame used is stainless steel or corrosion resistant polymer or the two combination to this filter.
(3) beneficial effect
Technique scheme has following advantage: enlarged the purposes scope of existing laboratory centrifuge, i.e. sedimentation separation expands isolated by filtration to; And overcome the defective of prior art, when centrifugalizing, avoided the generation of vapour lock, made filtration more smooth and easy.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1: bracing frame; 2: centrifuge tube; 3: porous plate; 4: the pipe lid; 5: annulus; 6: straight-bar.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1, use the typical circular test tube as centrifuge tube 2 in the present embodiment, bracing frame 1 is made by stainless steel material.Bracing frame 1 bottom is circular porous plate 3, top be one with the annulus 5 of centrifuge tube with the internal diameter stack pile, connect porous plates 3 and annulus 5 with 4 straight-bars 6.Annulus 5 can frame at the edge of centrifuge tube 2.
Filter bag is made by the chemical & blended fabric filter medium.
During use, earlier bracing frame 1 is put into centrifuge tube 2, put filter bag then, filter bag stretches in the centrifuge tube 2; Again feed liquid is added in the filter bag, put into centrifuge to centrifuge tube 2 and carry out centrifugal filtration.
After filtering completion, filter cake is stayed in the filter bag, and filtrating gets into centrifuge tube 2 bottoms; Like the need washing leaching cake, then filter bag and bracing frame 1 are taken out, put into another root centrifuge tube and install, add the cleaning solution washing, and then repeat above-mentioned steps.
When running into the volatile or material of solvent and be prone to the filtration of situation such as moisture absorption, facile hydrolysis, can after adding feed liquid in the filter bag, cover upper tube cap 4 immediately, avoid volatilization, absorb air moisture.
Bracing frame in the foregoing description uses the corrosion resistant polymeric material, can also alleviate the weight of bracing frame.
Use the filter in the foregoing description to separate 70～80% massecuite.Centrifuge speed when 3000～4000 change, 10-15 minute filters and to accomplish, and obtains crystallization and molasses, wherein crystallization is dry, loose.
Can find out that by above embodiment the utility model embodiment puts into centrifuge tube through adopting with filter bag, and in centrifuge tube, the new mode of bracing frame is installed, and separating effect and efficient all are greatly improved.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of the utility model.
