Abstract
The utility model belongs to chemical experimental instrument field, relates to a kind of half page of mouth centrifuge tube, comprises centrifuge tube body, at the mouth of pipe of centrifuge tube body, half page of bent is set; Half page of described bent is made up of level board and hang plate, and fluid hole is wherein set on level board, flows out for extract.The utility model is simple in structure, easy to operate, by half page of bent is set at the centrifugal mouth of pipe, can effectively intercept various solid impurities floating in testing sample solution, avoid it together to flow out with extract, reduce the contaminated probability of sample, increased work efficiency, improved the degree of accuracy of analysis result.
Description
Technical field
The utility model belongs to chemical experimental instrument field, relates to a kind of centrifuge tube, specifically a kind of half page of mouth centrifuge tube.
Background technology
The analysis of the available state composition (as Soil Available Copper, manganese, zinc, iron etc.) of soil mineral is the conventional project of soil analysis, in analytic process, often adopt centrifugal process to extract the active ingredient in pedotheque, in the centrifuge tube that claims to have sample, add a certain amount of extract, centrifugal on ultrasonic wave or the rearmounted centrifuge of oscillation treatment, isolate testing sample solution.After centrifugal treating, in pedotheque, active ingredient to be measured is dissolved in the middle of extract, and remaining sample particle residue is under the effect of powerful centrifugal force, and precipitation condenses in centrifuge tube bottom, gets transfer supernatant liquor, becomes testing sample solution.Owing to being more or less mingled with the root of plant in most of soils sample, wood scurf and other solid organic matters impurity etc., more solid impurity adrift in solution to be measured after centrifugal treating, in the time getting transfer upper strata extract, floating solid impurity can together flow out with extract, if now measure for directly going up machine, to stop up instrument pipeline, affect measurement result, therefore conventionally adopt the method for Filter paper filtering to remove floating impurity, but cross this method complex operation, strengthen workload and increased again the contaminated chance of sample solution, the degree of accuracy of impact analysis result.
Utility model content
The purpose of this utility model is that a kind of half page of mouth centrifuge tube is provided for the deficiencies in the prior art, by half page of bent is set at the centrifugal mouth of pipe, can effectively intercept various solid impurities floating in testing sample solution, avoid it together to flow out with extract, increase work efficiency, reduce the contaminated probability of sample, improved the degree of accuracy of analysis result.
The technical scheme that the utility model adopts:
A kind of half page of mouth centrifuge tube, comprise centrifuge tube body, it is characterized in that, at the mouth of pipe of centrifuge tube body, half page of bent (its structure is similar to the spacer body that longitudinal section is " ∠ " shape structure) is set, thus the mouth of pipe of centrifuge tube body is separated: a side is injection port, be convenient to sample and liquid feeding, opposite side is liquid outlet, flows out for extract; Half page of described bent is made up of level board and hang plate, and fluid hole is wherein set on level board, flows out for extract.In operating process, after high speed centrifugation separates, centrifuge tube body is tilted along liquid outlet direction, the sample extracting solution fluid hole from level board flows out, solid floating thing is intercepted by level board, extract is poured out collection through the liquid outlet of the centrifuge tube mouth of pipe, thereby has obtained limpid sample extracting solution.
The mouth of pipe wall arranged outside screw thread of described centrifuge tube body, facilitates with helixseal lid injection port screwing hermetic.
Described fluid hole is arranged on the binding site place of the tube wall of level board and centrifuge tube body.
The utility model is simple in structure, easy to operate, by half page of bent is set at the centrifugal mouth of pipe, can effectively intercept various solid impurities floating in testing sample solution, avoid it together to flow out with extract, reduce the contaminated probability of sample, increased work efficiency, improved the degree of accuracy of analysis result.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of half page of bent of the present utility model.
In figure: 1, centrifuge tube body; 2, screw thread; 3, half page of bent; 4, level board; 5, hang plate; 6, fluid hole.
Detailed description of the invention
Below in conjunction with accompanying drawing with by embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
In the structure shown in Fig. 1, the utility model comprises centrifuge tube body 1, at mouth of pipe wall arranged outside screw thread 2, the mouth of pipe of centrifuge tube body arranges half page 3 of bent, the mouth of pipe of centrifuge tube body is separated: left side is injection port, be convenient to sample and liquid feeding, right side is liquid outlet, flows out for extract.
In the structure shown in Fig. 2, the designed bent of the utility model is made up of level board 4 and hang plate 5 for half page 3, fluid hole 6 is wherein set on level board, flow out for extract, fluid hole 6 is preferably positioned at the binding site place of the tube wall of level board and centrifuge tube body, occurs residual can avoid toppling over extract time.
While extracting the active ingredient in pedotheque, pedotheque is inserted in centrifuge tube body 1, adds extract, with helixseal lid by injection port screwing hermetic; By centrifuge tube put on centrifuge, carry out centrifugal, then centrifuge tube body is tilted along liquid outlet direction, the extract fluid hole 6 from level board 4 flows out, solid floating thing is intercepted by level board 4, extract is poured out collection through the liquid outlet of the centrifuge tube mouth of pipe, thereby has obtained limpid sample extracting solution.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
