The invention belongs to the technical field of sampling devices for inspection, and particularly relates to a sampling device for biotechnological product inspection. The device comprises a liquid suction pipe, a sealing cover, a piston plate and a power bin; a liquid suction opening is formed in the bottom of the liquid suction pipe; the top of the liquid pumping pipe is screwed with the sealingcover; the piston plate is arranged in the liquid pumping pipe in a sliding manner; the top of the piston plate is fixedly connected with one end of a spring, and the other end of the spring is fixedly connected to the top inner wall of the sealing cover; a power bin is fixedly arranged on the edge of the outer side wall of the sealing cover; and a circular gear disc is arranged in the power bin.Liquid medicine sampling can be achieved through one-hand operation, then sampling can be conducted with one hand, medicine is put into the sampling bottle with the other hand to be sealed, meanwhile, the upward moving speed of the piston plate can be controlled through the downward moving speed of the straight gear plate, then the sampling speed is controlled, and the situation that the samplingspeed is too high, so that the sampling amount greatly exceeds the actually needed liquid medicine amount is avoided, so sample waste is avoided.
Description
technical field [0001] The invention belongs to the technical field of sampling devices for testing, in particular to a sampling device for testing biotechnology products. Background technique [0002] Biotechnology is the use of scientific technology and biotechnology to transform agriculture or other aspects. It is defined by the National Science and Technology Council of the United States as "biotechnology includes a series of technologies that can use organisms or cells to produce the products we need. These new technologies include gene recombination, cell fusion and some biological manufacturing procedures. [0003] When testing biotechnology products, it is necessary to take liquid from the stock solution tank, and at the same time, it is necessary to extract reagents for testing the stock solution. When sampling, syringes are often used for sampling in the prior art, and syringes are easy to operate. , simple structure, etc., but the following disadvantages still ex...
