Description
Technical field
The utility model relates to test tubes, and in particular to a kind of for extracting the test tube of experiment.
Background technique
Test tube is a kind of laboratory commonly reaction vessels, and the common test tube that laboratory uses at present can be used as extraction instrument
Component for a small amount of sample is extracted.Sample need to be usually totally submerged in extracting solution when extracting experiment, but for structure
More loose fluffy scattered sample is dissipated because itself is fluffy, the characteristic that density is small not can guarantee can be complete under conditions of specific solid-to-liquid ratio
It is immersed in extractant entirely, causes sample component to be extracted insufficient.
Currently used solution is usually that sample size or fixed sample are reduced when shaking test tube, fixed extraction agent capacity
After increasing Extraction solvent extraction when amount, then means of different is used to be concentrated, thus achieve the purpose that specific solid-to-liquid ratio is extracted, but
It is that these are complex for operation step and the effect is unsatisfactory, therefore, it is necessary to study a kind of new solutions.
Summary of the invention
The purpose of this utility model is that loose fluffy scattered sample can not be made complete in extracting experiment for common test tube
It is immersed in the problems in extractant, the utility model provides a kind of test tube easy to operate and time saving and energy saving, by adding in tube body
Enter a roundness mess pressing plate, achievees the purpose that squeezing sample diminution volume is totally submerged sample in extractant.
The utility model, which is that the following technical solution is employed, to be realized:
A kind of further includes push rod for extracting the test tube of experiment, including test tube tube body and test tube plug, and the surface of push rod is arranged
External screw thread；It is provided with circular hole in the middle part of the test tube plug, internal screw thread is set on circular hole wall, and push rod is passed through from circular hole, the surface of push rod
External screw thread and circular hole wall on screw-internal thread fit；Push rod is placed in the intracorporal one end of test tube pipe and circular netted pressing plate is arranged, and sets
Handle, rotating handle are set in one end outside test tube tube body, push rod drives netted pressing plate to move up and down in test tube tube body.
Further, the outer wall of the test tube tube body is equipped with containing mark.
Further, the test tube plug is connect with the mouth thread of test tube tube body.
Further, the end face of the handle is plane.
Further, the test tube tube body, netted pressing plate, push rod material be glass, polytetrafluoroethylene (PTFE), polyvinyl chloride,
It is a kind of in polypropylene.
Compared with prior art, the utility model is additionally arranged the test tube plug with push rod on the basis of common test tube, leads to
Crossing rotating handle keeps push rod mobile to test tube bottom, drives netted pressing plate to squeeze sample, makes sample volume reduction, it is complete to reach sample
The purpose being immersed in extractant entirely.Common test tube provided by the utility model, successfully solving loose fluffy scattered sample can not
It is totally submerged in extractant under conditions of specific solid-to-liquid ratio, sample component is caused to extract insufficient problem, and structure
Simply, easy to use, it is highly suitable for laboratory popularization and application.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the test tube that embodiment is used to extract experiment；
Fig. 2 is the structural schematic diagram of embodiment test tube plug；
Fig. 3 is the structural schematic diagram of the netted pressing plate of embodiment.
In above each figure: 1, test tube tube body；2, test tube plug；21, circular hole；3, push rod；4, netted pressing plate；5, handle.
Specific embodiment
In order to which the above objects, features, and advantages of the utility model are more clearly understood, with reference to the accompanying drawing and
Embodiment is described further the utility model.It should be noted that in the absence of conflict, embodiments herein and
Feature in embodiment can be combined with each other.
Embodiment
The present embodiment provides it is a kind of for extract experiment test tube, as shown in Figure 1, include test tube tube body 1, test tube plug 2 and
Delivery device three parts, delivery device are made of push rod 3, netted pressing plate 4 and handle 5.Test tube tube body 1 is existing common examination
Shape possessed by managing, can use common flat mouth test tube or wiredrawn edge test tube.Test tube plug 2 is arranged in the oral area of test tube tube body 1,
The middle part of test tube plug 2 is provided with circular hole 21, and internal screw thread is arranged on circular hole wall, and push rod 3 is passed through from circular hole, the surface setting of push rod 3
Screw-internal thread fit on external screw thread, with circular hole wall.Push rod 3 is placed in one end in test tube tube body 1 and circular netted pressure is fixedly installed
Plate 4, the netted perpendicular state in test tube wall of pressing plate 4, hole of the netted pressing plate with latticed hole or other shapes, Fig. 1
In be not shown, be rectangular referring to the netted pressing plate of Fig. 3.Push rod 3 is placed in the fixed setting of one end outside test tube tube body 1 handle 5, rotation
Handle 5, push rod 3 drive netted pressing plate 4 to move up and down in test tube tube body 1.
When extracting experiment, first sample is put into and is filled in the test tube tube body 1 of extractant in advance, then the examination that push rod 3 will be had
