Abstract
The utility model relates to a centrifugal micro-filter. The centrifugal micro-filter mainly comprises a porous partition plate (1), filter paper (3), a silicon rubber ring (4), a centrifugal cylinder (5), a turned edge (6), an internal thread (7), a centrifugal cup (8) and an external thread (11), and is characterized in that the filter paper (3) is inlaid on the porous partition plate (1), the periphery of the filter paper (3) is in close contact with the lower surface of the silicon rubber ring (4), the periphery of the silicon rubber ring (4) is in close connection with a groove on the inner side of the centrifugal cylinder (5) in an interference way, the internal thread (7) is turned on the inner side at the lower end of the centrifugal cylinder (5), the external thread (11) is turned on the outer side at the upper end of the centrifugal cup (8), and the centrifugal cylinder (5) is in close rotary connection with the external thread (11) of the centrifugal cup (8) through the internal thread (7), thereby constituting the centrifugal micro-filter. When in use, a solution to be filtered is directly poured into the centrifugal micro-filter, a centrifuge is opened, filtrate is separated to the bottom of the centrifugal cup (8) under the centrifugal action, and precipitates are isolated on the filter paper (3), thus the filtration is very convenient, and the loss of the precipitates is very low.
Description
Technical field
The utility model relates to a kind of chemical laboratory and the research office filters the centrifugal microfilter of micro solution fast.
Background technology
Filter be a kind of in the laboratory the very high instrument of frequency of utilization; Mostly existing filter is Buchner funnel or glass funnel; This type normal pressure or decompression type filter only are suitable for constant or semimicro is filtered, when carrying out the micro liquid filtration, because reagent and precipitation capacity are few; Not only very easily cause the loss of analytic sample, and deposition is difficult to take out.How to design a kind of microfiltration instrument that is suitable for carrying out the convenient and efficient of microfiltration, become the realistic problem that experimental teaching and research practice field need to be resolved hurrily at present.
Summary of the invention
The purpose of the utility model is to provide a kind of can carry out the centrifugal microfilter that micro solution is filtered by convenient and efficient.Centrifugal microfilter is made up of porous barrier, upper groove, filter paper, silicon rubber loop, concentrator bowl, crimping, internal thread, Centrifuge Cup, convex edge, low groove and external screw thread; It is characterized in that: the upper surface of porous barrier has one to recessed upper groove, and the porous barrier lower surface has a low groove to fovea superior, studs with filter paper in the upper groove; The periphery of filter paper upper surface closely contacts with the silicon rubber loop lower surface; The lower surface of filter paper is close to upper groove, and silicon rubber loop is with interference mode and concentrator bowl lower end inboard groove close proximity, and the concentrator bowl port is a crimping; Sidecar has internal thread in the concentrator bowl lower end; One circle convex edge is arranged at the Centrifuge Cup top, and the low groove of convex edge and porous barrier closely interlocks, and the outer sidecar in Centrifuge Cup upper end has external screw thread; Concentrator bowl closely spins through the external screw thread of internal thread and Centrifuge Cup, forms centrifugal microfilter thus.
The advantage of the utility model is: directly solution to be filtered is poured in the centrifugal microfilter; Open centrifuge, filtrating is split into the Centrifuge Cup bottom under the action of the centrifugal, and deposition is isolated on the filter paper; Filtration is got up very convenient, and the deposition loss is few.
The beneficial effect of the utility model is for laboratory and research office's micro liquid filter a kind of easy to operate, novel filtering apparatus that the deposition loss is few to be provided.
