Abstract

The utility model discloses a microfilter which can be used for filtering a trace solution very conveniently and efficiently. The microfilter mainly consists of an exhaust tube (1), a filtering flask (2), a suction tube (3), a flange upper conduit (6), a flange lower conduit (7), a stainless steel net (8), filtering paper (9), a silica gel plug (11) and a conical flask (12), and is characterized in that: the exhaust tube (1) is connected with a filtering tip of the filtering flask (2); the opening of the filtering flask (2) is connected with the flange upper conduit (6); the flange upper conduit (6) and the flange lower conduit (7) are in threaded connection; the stainless steel net (8) is embedded in an inner groove of the flange upper conduit (6); the stainless steel net (8) is cushioned by the filtering paper (9) below; the silica gel plug (11) is sleeved at the middle part of the outer side of the flange lower conduit (7); and the silica gel plug (11) is tightly plugged on the opening of the conical flask (12). The microfilter disclosed by the utility model has the advantages that: the microfilter is directly inserted into the filtering flask (2) containing liquid to be filtered, and then the microfilter can filter the liquid after being connected with a circular water vacuum pump without transferring the filtrate back and forth, thereby ensuring little precipitation loss and convenience in operation.

Description

Microfilter

Technical field

The utility model relates to the 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, this type funnel only is suitable for constant or semimicro and filters; When carrying out the filter of micro liquid; Because amount of reagent is few, precipitation capacity is also little, makes that not only deposition is difficult to take out; And very easily cause the loss of analytic sample, even can cause the failure of whole experiment.How can 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 microfilter that minute quantity solution filters by convenient and efficient.Microfilter is made up of exhaust tube, bottle,suction, suction pipe, rubber stopper, silicone tube, flange upper conduit, flange downcomer, stainless (steel) wire, filter paper, rubber ring, silica gel plug and conical flask; It is characterized in that: the suction filtration mouth of exhaust tube and bottle,suction joins, and the bottle,suction bottleneck is inserted with the rubber stopper of band suction pipe, and the upper end of suction pipe and silicone tube left end join; Silicone tube right-hand member and flange upper conduit join; Flange upper conduit and flange downcomer join through screw thread, and flange upper conduit inner groovy is embedded with stainless (steel) wire, are lined with filter paper below the stainless (steel) wire; The circumferential edge of filter paper closely contacts with the rubber ring upper surface; The rubber ring lower surface is embedded in the flange downcomer groove inside, and the outer middle side part of flange downcomer is with a silica gel plug, and silica gel jam-pack plug is on the conical flask bottleneck.

The advantage of the utility model is: directly microfilter is inserted on the bottle,suction bottleneck that fills liquid to be filtered, connects the recirculated water vavuum pump, just can filter, do not need to shift back and forth filtrating, the deposition loss is few, simple operation.

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 little is provided.

Description of drawings

The drawing of accompanying drawing 1 is explained as follows:

Fig. 1 is that figure cuts open in the office of microfilter.

The explanation of each label is following among Fig. 1:

(1) exhaust tube, (2) bottle,suction, (3) suction pipe, (4) rubber stopper, (5) silicone tube, (6) flange upper conduit, (7) flange downcomer, (8) stainless (steel) wire, (9) filter paper, (10) rubber ring, (11) silica gel plug, (12) conical flask.

The specific embodiment

Among Fig. 1, exhaust tube 1 joins with the suction filtration mouth of bottle,suction 2, and bottle,suction 2 bottlenecks are plugged with the rubber stopper 4 of band suction pipe 3, and the upper end of suction pipe 3 and silicone tube 5 left ends join; The cylindrical straight siphunculus that suction pipe 3 is 7 * 80 millimeters of Φ, 1 millimeter of wall thickness, be made by polytetrafluoroethylmaterial material; Silicone tube 5 right-hand members and flange upper conduit 6 join, and flange upper conduit 6 all is to join by the polytetrafluoroethylmaterial material making and through screw thread with flange downcomer 7, and flange upper conduit 7 inner groovies are embedded with stainless (steel) wire 8; Stainless (steel) wire 8 is 1 millimeter of circular punching net, mesh diameter of 10 millimeters of diameters; Be lined with filter paper 9 below the stainless (steel) wire 8; The diameter of filter paper 9 is 10 millimeters; The circumferential edge of filter paper 9 closely contacts with rubber ring 10 upper surfaces, and rubber ring 10 is silicon rubber annulus of 10 millimeters of diameter of phi, 5 millimeters of center bore Φ, 1 millimeter of thickness, and rubber ring 10 lower surfaces are embedded in flange downcomer 7 groove inside; Flange downcomer 7 outer middle side parts are with a silica gel plug 11, and silica gel plug 11 is tightly filled on the bottleneck of conical flask 12.
