Sampling device easy to classify and used for biological study

Abstract

The invention discloses a sampling device easy to classify and used for biological study. The sampling device comprises a sampling tube, a first elastic ball bag, an installation ring, a first reset spring and a second reset spring, wherein the first elastic ball bag is arranged at an upper end of the sampling tube, the installation ring is fixedly arranged on an outer wall of the sampling tube, sample liquid collection bottles are connected with an outer side of the installation ring, a connection groove is formed in a baffle plate, the first reset spring is arranged in the connection groove,a lower end of the first reset spring is connected with an upper surface of the baffle plate, and a first connection rope is fixedly arranged at an upper surface of the baffle plate. In the samplingdevice easy to classify and used for biological study, the sample liquid collection bottles, the baffle plate and the connection groove are arranged, the baffle plate can be stored in the connection groove during sampling of a liquid, so that the liquid in the sampling tube can enter the sample liquid collection bottles through a port; and by arranging a plurality of sample liquid collection bottles, sampling and storage of various liquids can be achieved, and classified storage of the sample liquids is achieved.

Description

technical field [0001] The invention relates to the technical field of biology, in particular to an easy-to-classify sampling device for biological research. Background technique [0002] Biology is a natural science that studies biological functions and development laws, including the study of plants, animals and microorganisms. When studying them, it often cooperates with observation instruments to study and analyze biological cells and living environments. When the culture fluid is studied and observed, the fluid is generally sampled, and then the sample is tested in order to know the composition and characteristics of the fluid, but there are still some shortcomings in the existing sampling device: [0003] 1. When the existing sampling device samples the culture fluid, etc., it usually samples the liquid through a sampler such as a straw. After sampling the liquid, the device cannot store the liquid to a certain extent, and the device can only sample one It is not conv...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of biological research sampling device that is easy to classify, to solve the problem that the existing sampling device on the market proposed by the above-mentioned background technology cannot store the liquid to a certain extent after sampling the culture fluid etc. And the device can only sample one kind of liquid at a time, it is not convenient to classify and store the sampled liquid, and it is not convenient to clean the inner wall of the device in time after the device is used
