Abstract

A simple microfilter is mainly composed of a pressurization ball (1), a pressurization pipe (3), a rubber plug (4), a reagent bottle (5), a flow guiding pipe (6), a connecting pipe (7), a U-shaped pipe (8), a cone-shaped pipe (9), a flange (11), filter paper (13), a rubber ring (14) and a square column (15). The simple microfilter is characterized in that the pressurization ball (1) is connected with the pressurization pipe (3), the lower end of the pressurization pipe (3) is inserted into a left end hole of the rubber plug (4) in an interference mode and penetrates through the left end hole of the rubber plug (4), the rubber plug (4) is plugged on an opening of the reagent bottle (5), the flow guiding pipe (6) is inserted into a right end hole of the rubber plug (4), and the upper end of the flow guiding pipe (6) is connected with the cone-shaped pipe (9) through the connecting pipe (7) and the U-shaped pipe (8). The cone-shaped pipe (9) is connected with the flange (11), the bottom edge of the cone-shaped pipe (9) is in close contact with the upper surface of the filter paper (13), the lower surface of the filter paper (13) is tightly pressed on the periphery of the upper surface of the rubber ring (14), and the lower surface of the rubber ring (14) is supported through the square column (15). When the simple microfilter is in use, the rubber plug is inserted into the bottle opening of the reagent bottle containing liquid to be filtered, air is filled into the bottle so that liquid can be pressed into the filter to be filtered, and the direct filtering method enables sedimentation loss to be little and is simple and convenient to operate.

Description

Simple and easy microfilter

Technical field

The utility model relates to the simple and easy microfilter of the convenient quick filtration minute quantity liquid of a kind of chemical laboratory and research office.

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, and this type funnel only is suitable for constant or semimicro is filtered, when carrying out the filtration of micro liquid; Because amount of reagent and precipitation capacity are few; Not only very easily cause the loss of analytic sample, and make that deposition is difficult to take out, even can cause the failure of whole experiment.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 simple and easy microfilter that micro solution is filtered by convenient and efficient.Simple and easy microfilter is made up of pressurizing ball, control valve, forcing pipe, rubber stopper, reagent bottle, mozzle, tube connector, U type pipe, conical pipe, convex edge, flange, groove, filter paper, rubber ring, box type column and boss; It is characterized in that: the control valve of pressurizing ball lower end and forcing pipe upper end join; The forcing pipe lower end is inserted through rubber stopper with the interference mode from rubber stopper left end hole, and closely plug is on the reagent bottleneck for rubber stopper, and the rubber stopper right-hand member is inserted with a mozzle; Insert in the bottle mozzle lower end; The mozzle upper end joins through tube connector and lower end, a U type pipe left side, and the upper end of U type pipe bottom righthand side and conical pipe joins with bonding mode, and the lower end of conical pipe is interlockingly connected through the groove at convex edge and flange middle part; The base of conical pipe closely contacts with the filter paper upper surface; The filter paper lower surface tightly is pressed in the periphery of rubber ring upper surface, and the rubber ring lower surface is supported by box type column, and box type column is connected on the boss.

The advantage of the utility model is: during use; Directly the rubber stopper insertion with simple and easy microfilter fills on the reagent bottle or taper bottleneck of liquid to be filtered; The extruding pressurizing ball is inflated in bottle, and gas pressure just can be pressed into filter to liquid and filter; This Direct Filtration mode precipitates loss and pollutes and lack, and simple operation.

The beneficial effect of the utility model is, but provides a kind of and do not need just Direct Filtration of secondary transferring for laboratory and research office's micro liquid filter, and easy to operate novel micro filter.
