Convenient sampling test tube

Abstract

The invention discloses a portable sampling test tube, which comprises a test tube body, the top of the test tube body is provided with an opening, a rubber stopper is embedded in the opening of the test tube body, and the lower end of the rubber stopper is vertically and fixedly connected with a sampling tube. The sampling spoon includes a spoon handle and a spoon body, the spoon handle and the spoon body are integrally connected and fixed, and the spoon handle includes a fixed rod handle vertically fixed at the lower end of the rubber stopper and a telescoping The movable rod handle in the fixed rod handle, the lower end of the movable rod handle is fixedly connected with the spoon body, the front end surface of the test tube body is provided with a capacity scale, and two ends of the test tube body are symmetrically arranged. Anti-slip pads, the two anti-slip pads are relatively arranged at the central position of the end surfaces on both sides of the test tube body. Through the above method, the present invention can take samples through the built-in sampling spoon, which is convenient and quick, and can be applied to the sampling work of test tubes of different lengths.

Description

technical field [0001] The invention relates to the field of sampling test tubes, in particular to a portable sampling test tube. Background technique [0002] At present, test tubes are often used in chemical experiments for sampling and testing, but most of the test tubes used today are ordinary test tubes. Ordinary test tubes lack corresponding test tube covers, making the samples vulnerable to contamination by external substances, affecting the test results, and lack of corresponding sampling. It is difficult to sample, and sampling cannot be performed after the sampler is accidentally lost, and there are certain usage conditions. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a convenient sampling test tube, which can be sampled through a built-in sampling spoon, which is convenient and fast, and can be used for sampling work of test tubes of different lengths. [0004] In order to solve the above technic...
