Abstract
The utility model discloses a filter cover of a soil sample effective state analysis centrifugal tube. The filter cover comprises a mesh cover and an outer cover, wherein the mesh cover comprises a mesh cover port at one end and a liquid outlet at the other end, a thread is arranged in the mesh cover port, the mesh cover port can be matched, screwed and sealed with a centrifugal tube mouth, and a filter mesh is arranged between the mesh cover port and the liquid outlet; and the outer cover comprises a sealed cover top and an outer cover port, and a thread is arranged in the outer cover port. The filter cover disclosed by the utility model can effectively separate various floating solid impurities in a sample solution to be tested, avoid an experimental link of adopting filter paper to filter, improve the working efficiency, reduce the probability of polluting a sample and improve the accuracy of an analysis result.
Description
Technical field
The utility model relates to a kind of pedotheque available state analysis centrifugal pipe filtering cover.
Background technology
Soil available composition (as Soil Available potassium, exchangeable calcium, magnesium etc.) is the conventional detection project of soil analysis, in analytic process, often adopt the active ingredient in centrifugal process extraction pedotheque, namely add a certain amount of extract in claiming to have the centrifuge tube of sample, centrifugal on ultrasonic wave or the rearmounted centrifuge of oscillation treatment, isolate testing sample solution.Through after centrifugal treating, in pedotheque, active ingredient to be measured is dissolved in the middle of extract, and under the effect of powerful centrifugal force, precipitation condenses in bottom centrifuge tube remaining sample particle residue, gets the transfer supernatant liquor, namely becomes testing sample solution.Due to the root that more or less is being mingled with plant in the most of soils sample, wooden scurf and other solid organic matters impurity etc., more solid impurity adrift in solution to be measured after centrifugal treating, if being used for directly going up machine this moment measures, to stop up instrument pipeline, impact is measured, solution to be measured must be carried out filtration treatment, so not only increase workload but also increased the contaminated chance of sample solution, the degree of accuracy of impact analysis result.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to use, pedotheque available state analysis centrifugal pipe filtering cover that can repeatedly utilize, can effectively intercept various solid impurities floating in testing sample solution.
To achieve these goals, the technical solution of the utility model is: a kind of pedotheque available state analysis centrifugal pipe filtering cover is provided, wherein, formed by square and enclosing cover, described square comprises the square mouth of an end and the liquid outlet of the other end, establish screw thread in the square mouth, the square mouth can coordinate screwing hermetic with the centrifugal mouth of pipe, be provided with screen pack between square mouth and liquid outlet, liquid outlet peripheral hardware screw thread, described enclosing cover comprise sealing caping and with the enclosing cover mouth, establish screw thread in the enclosing cover mouth, can coordinate screwing hermetic with square liquid outlet external screw thread.
The advantage of the utility model pedotheque available state analysis centrifugal pipe filtering cover:
(1) the utility model can effectively intercept various solid impurities floating in testing sample solution, avoids adopting the experiment link of Filter paper filtering, increases work efficiency, and has reduced the contaminated probability of sample, improves the degree of accuracy of analysis result.
(2) the utility model adopts the sealing of plastic whorl spiral cover, and good airproof performance is avoided the phenomenon of leakage.
(3) the utility model can repeatedly use, and has saved the cost that filter paper consumes.
(4) the utility model is made and is simple to operate, washs and deposits conveniently.
Description of drawings
Fig. 1 is the structural representation of the utility model pedotheque available state analysis centrifugal pipe filtering cover;
In figure: 1, centrifuge tube; 2, square; 3, screen pack; 4, liquid outlet; 5, enclosing cover.
The specific embodiment
For the technology contents that describes the utility model pedotheque available state analysis centrifugal pipe filtering cover in detail, structural feature, below in conjunction with embodiment and coordinate accompanying drawing to be described further.
As shown in Figure 1, the utility model pedotheque available state analysis centrifugal pipe filtering cover is comprised of square 2 and enclosing cover 5.Described square 2 comprises the square mouth of an end and the liquid outlet 4 of the other end, establish screw thread in the square mouth, the square mouth can coordinate screwing hermetic with 1 mouthful of centrifuge tube, is provided with screen pack 3 between square mouth and liquid outlet, liquid outlet peripheral hardware screw thread can screw with enclosing cover mouth screw-internal thread fit; Described enclosing cover 5 comprises the caping of sealing and revolves friction tight enclosing cover mouth with square lid mouth, establishes screw thread in the enclosing cover mouth, can coordinate screwing hermetic with the liquid outlet external screw thread of square 2.Screen pack 3 is used for filtering liquid impurity to be measured.
Concrete operations: with enclosing cover 5 and square 2 liquid outlet place screwing hermetics, be combined into filtering cover, then filtering cover covered on the centrifuge tube that fills pedotheque and extract screwing hermetic.Pass through after ultrasonic wave or vibration and centrifugal treating until the centrifuge tube sample, open enclosing cover, directly get the centrifuge tube supernatant, solution is by the liquid outlet of square, transfer to and become solution to be measured in other test tube, impurity floating in solution is intercepted by the screen pack on square, guarantees the clear of solution to be measured.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
Claims (1)
1. pedotheque available state analysis centrifugal pipe filtering cover, it is characterized in that: formed by square and enclosing cover, described square comprises the square mouth of an end and the liquid outlet of the other end, establish screw thread in the square mouth, the square mouth can coordinate screwing hermetic with the centrifugal mouth of pipe, is provided with screen pack between square mouth and liquid outlet, liquid outlet peripheral hardware screw thread, described enclosing cover comprises caping and the enclosing cover mouth of sealing, establishes screw thread in the enclosing cover mouth, can coordinate screwing hermetic with the liquid outlet external screw thread.
