Description
technical field:
The present invention relates to the microfiltration device that a kind of laboratory is used, belong to filter apparatus for filtering liquid technical field.
background technology:
Device for liquid filtering is divided into positive pressure type and negative-pressure type two class, and positive pressure type filtration unit is used for the filtration of a small amount of liquid, as several milliliters to tens milliliters, namely belongs to microfiltration device; Negative-pressure type filtration unit then for the filtration of large quantity of fluid, tens milliliters to hundreds of milliliter, and even thousands of milliliter.Existing microfiltration device has needle tubing filtrator, needs pre-filtered liquid to load in needle tubing, applies positive pressure, make liquid reach the object of filtration by filtrating chip by pushing syringe piston.Needle tubing is generally glass needle tubing and disposable plastic needle tubing, and the former can reuse.But glass needle tubing requires that needle tubing piston and sleeve pipe are strictly sealed and matched, this is quite difficult concerning the filtration of a large amount of different sample.And the latter adopts disposable medical syringe, but then inapplicable to some liquid flux dissolved or corrosivity is strong, and also use cost is also relatively high.Also have a kind of microfiltration apparatus, namely with filter membrane or sampling suction nozzle or the filling gun head filtration unit of filtering post, be usually applicable to the micro liquid of Molecular level study, use cost is higher, is difficult to the filtration being suitable for milliliter level liquid.In real work, often run into the filtration of a few ml sample in enormous quantities, as analytical equipments such as gas chromatograph, liquid chromatograph, ion chromatograph, Continuous Flow Analysis instrument, the sample size needed for analysis is all little, but the sample number of Simultaneously test is a lot of again.All need before these instrument loadings to filter, for adapting to large batch of filtration needs, the design people is through long-term practice, develop a kind of features simple structure, filtered efficient and reusable microfiltration device, overcome the deficiencies in the prior art well, test proves, effect is good.
summary of the invention:
The object of the invention is to the deficiency overcoming prior art, provide a kind of simple and efficient, be easy to operate, can be used in the rapid filtering device of multiple fluid sample.
Rapid filtering device for laboratory fluids sample of the present invention comprises: with air admission hole airtight transparent glass cover, the back up pad of cloche, back up pad be equipped with the tapered tube of band by-pass cock for putting and be provided with the pedestal of two fixed bars, pedestal has the hole fixedly can putting chromatogram bottle, two fixed bars are connected and fixed bolt and bolt sleeve, bolt sleeve and back up pad are connected as a single entity, and are provided with the fixed head of liquid-transfering gun rifle head bore between the tapered tube and corresponding aperture of band by-pass cock.
Air admission hole on described airtight transparent glass cover is placed in the centre of airtight transparent glass cover, and a rain glass is housed.
The tapered tube of 20 band by-pass cockes described back up pad is equipped with.
Described pedestal has the hole that 20 fixedly can be put chromatogram bottle.
The tapered tube of described band by-pass cock and liquid-transfering gun rifle head bore and fixedly can to put the hole of chromatogram bottle vertical point-blank.
The invention has the advantages that: filter process is quick, easy and easy to operate, easy to carry, place, external environment condition factor need not be considered, saving of work and time, filter efficient and reusable, multiple fluid sample for chromatogram or mass spectrophotometry can be filtered simultaneously.
accompanying drawing illustrates:
Fig. 1 is apparatus structure schematic front view of the present invention.
Fig. 2 is the schematic top plan view of Fig. 1.
In figure, the airtight transparent glass cover of 1-, 2-fixed bar, 3-back up pad, 4-fixed head, 5-pedestal, 6-fixedly can put the hole of chromatogram bottle, 7-liquid-transfering gun rifle head bore, and 8-is with the tapered tube of by-pass cock, 9-bolt and bolt sleeve, 10-air admission hole.
embodiment:
As shown in Figure 1-2, laboratory fluids sample filtration device of the present invention comprises: with air admission hole 10 airtight transparent glass cover 1, the back up pad 3 of cloche 1, back up pad 3 be equipped with the tapered tube 8 of band by-pass cock for putting and be provided with the pedestal 5 of two fixed bars 2, pedestal 5 has the hole 6 fixedly can putting chromatogram bottle, two fixed bars 2 are connected and fixed bolt and bolt sleeve 9, bolt sleeve 9 and back up pad 3 are connected as a single entity, and are provided with the fixed head 4 of liquid-transfering gun rifle head bore 7 between the tapered tube 8 and corresponding aperture 6 of band by-pass cock.Described airtight transparent glass cover 1 is provided with air admission hole 10.Described back up pad 3 is equipped with the tapered tube 8 of 20 band by-pass cockes, described pedestal 5 has the hole 6 that 20 fixedly can be put chromatogram bottle.
The present invention adopts commercially available prod or material to prepare according to a conventional method.Pedestal 5 adopts metal material, to increase the stability of admittedly whole device, length preferably has 30cm long, airtight transparent glass cover 1 should select the material of enough air pressure resistances, and with back up pad 3 good airproof performance, the band tapered tube 8 of by-pass cock and the hole 6 of fixedly putting chromatogram bottle on the liquid-transfering gun rifle head bore 7 of fixed head 4 and pedestal 5 should vertical point-blank.
