Description
Technical field
The utility model relates to a kind of experiment centrifuge tube, especially a kind of be used for agriculturally utilizing during the various physical and chemical index of chemical analysis methods soil nutrient content, soil extract soil " stoste " assemblied stereo formula centrifuge tube.
Background technology
Traditionally using the method for agriculture chemistry methods analyst soil nutrient content, the various physical and chemical index of soil, is all generally according to " soil is air-dry for a long time---sieve earth removal assorted---adding distil water lixiviate---is filtered ", a series of loaded down with trivial details, complicated flow process.Meanwhile, the soil liquid extracted in such a way can not the real physical and chemical index of reflect soil really, because soil " stoste " is only the most truly, the solution that the most directly contacts with root system of plant, and every physical and chemical index of soil " stoste " reflect soil.Material in the process that soil is air-dry in soil experienced by complicated change, and as metallic element oxidation can occur, the cell meeting of microorganism is dead or form spore etc., and original state has been changed.The method of existing acquisition soil stoste has percolate method, and this method with the increase of soil irrigation quantity, may can dilute the soil liquid, can not accurately, real reflect soil physical and chemical index.Secondly, also useful " milling process " obtains soil stoste, and this method requires higher to soil moisture content, is limited to the reason of soil moisture content size simultaneously, needs a large amount of soil, and this Measures compare is time-consuming, effort.Also has a kind of method, utilize hydro-extractor by soil " stoste " centrifuging out exactly, but general conventional test centrifuge tube small volume, quality of materials is poor, if soil quality is overweight in use procedure, centrifuge speed is excessive, very easily there is " booster " phenomenon, and soil has adsorption moisture effect, be difficult to obtain soil " stoste " with general conventional test centrifuge tube, this method result of use is also undesirable.Therefore, if developed, a kind of structure is simple, size to fit, and it is easy to use, reliable and stable, and the soil obtained " stoste ", can the special-purpose taking liquid device of the true soil liquid of reflect soil physicochemical property, to the work of physical form, Crop nutrient in research soil, tool is of great significance.
Summary of the invention
The purpose of this utility model be to provide a kind of structure simple, convenient and practical, can effectively be applied to centrifugal extraction soil " stoste ", use the Combined centrifuge tube for extracting soil stoste that is reliable and stable, that greatly increase work efficiency.
The utility model discloses a kind of Combined centrifuge tube for extracting soil stoste, it is characterized in that comprising pipe lid 1, centrifugal pipe core 5, filter plate 7, containing the cup-shaped base 11 getting stoste, described centrifugal pipe core 5 is provided with drain hole 3, liquid outlet 9, described drain hole 3 is provided with described pipe lid 1, be threaded connection between pipe lid 1 and drain hole 3, described liquid outlet 9 place is provided with filter plate 7, filter plate 7 is provided with multiple filter opening 8, filter plate 7 outer edge is provided with arc platform 10 in one week, and described cup-shaped base 11 is threaded with liquid outlet 9.The setting of described arc platform 10, can making the shape of filter plate 7 and liquid outlet 9 edge shape more fit, preventing cup-shaped base from causing rocking of filter plate 7 when taking off or install.
Filter paper 6 is preferably provided with inside described filter plate 7.Place filter paper, effectively can prevent the impurity blocking filter opening in stoste, also play a role in filtering simultaneously, and then the soil liquid comparatively clarified.
Described centrifugal pipe core 5 shape is preferably drum, and described pipe lid 1, cup-shaped base 11 are also preferably drum.
As preferably, described filter plate 7 shape is circular slab, and the cross sectional shape of described circular slab is straight plate 14.
Preferred as another kind, described filter plate 7 shape is circular slab, the cross sectional shape of described circular slab is arc 15, the described hole of filter opening 8 for being obliquely installed, namely filter opening 8 hole central axis 13 relative to filter plate central axis 12 shape in an angle, and the hole central axis 13 of multiple filter openings 8 on described filter plate 7 around the central axis 12 of filter plate in outwards radial.Inventive principle: the utility model utilizes centrifugation, makes the moisture in soil depart from soil under specific centrifugal speed.Collect soil " original " solution that this part water (soil stoste) namely can obtain without any conversion.
Described centrifugal pipe core 5, described pipe lid 1, cup-shaped base 11, filter plate 7 are made up of polytetrafluoroethylmaterial material.
Method of operating: turn on screw socket pipe lid, fresh soil is put into the centrifugal pipe core installing porous filter plate, and then screw socket stoste contained the cup-shaped base got and is installed to centrifugal pipe core (for the soil stoste obtaining clarifying can add one deck quantitative filter paper on filter plate), whole device tighten assemble just can be put in hydro-extractor centrifugal.
The heavy centrifugal reference data (30g wet soil) of 30g soil is as following table:
Above-mentionedly utilize centrifuge tube to obtain liquor capacity can to meet the requirement of most data analysis to sample size.
This Combined centrifuge tube selection is teflon, this material has excellent chemical stability, corrosion resistance, sealing, height lubricate not viscosity, electrical insulating property and good anti-aging endurance, in extraction soil stoste, can meet higher centrifugal speed to the soil liquid without any the good anti-aging endurance of interference.
General test centrifuge tube is less, and quality of materials is poor, use procedure once soil quality is overweight, centrifuge speed excessive easy generation " booster " phenomenon, and soil has adsorption moisture effect, can be difficult to obtain soil " stoste " with general centrifuge tube.This assembly type centrifuge tube can significantly improve extraction efficiency, quick, convenient, efficient, for soil agrochemistry analysis of experiments provides a kind of new technique in extraction soil stoste.
Compared with prior art, the utility model structure is simple, convenient and practical, is that one effectively can being applied to centrifugal extraction soil " stoste ", using the Combined centrifuge tube for extracting soil stoste that is reliable and stable, that greatly increase work efficiency.
