Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.
In order to solve the problem of the difficulty of taking a sample when testing sample specific surface area among the prior art, this application provides a sampling device.
As shown in fig. 1, the sampling device in the present application includes a grip portion 10 and a sampling tube 20. The sampling tube 20 has a containing cavity, the top surface of the sampling tube 20 is fixedly connected with the holding part 10, the side wall of the sampling tube 20 is provided with a sampling opening 21 communicated with the containing cavity, and the extending direction of the sampling opening 21 is the same as the axial direction of the sampling tube 20.
When the sampling device with the above structure is used, a weighed sample can be added into the accommodating cavity through the sampling opening 21. Then, in sending the sampling tube 20 into specific surface area test tube through gripping portion 10, after waiting that sampling tube 20 stretches into the bottom of test tube, rotate sampling tube 20 through gripping portion 10 to make the sample can get into the test tube through sample opening 21. In the process, the sample can be effectively prevented from being adhered to the tube wall of the test tube, so that the problem of difficulty in sampling when the specific surface area of the sample is tested in the prior art is effectively solved.
It should be noted that, in the process of feeding the sampling tube 20 into the test tube through the grip portion 10, the test tube and the sampling device need to be horizontally placed. And the sampling opening 21 needs to be placed upward.
