Description

Technical Field

[0001] The utility model mainly relates to the field of sampling equipment for culture fluid processing, in particular to a sampling device for cell culture fluid processing. Background Art

[0002] When sampling the culture fluid, the culture fluid needs to be sealed and preserved to ensure that the culture fluid is not contaminated and to prevent inaccurate detected data from misjudgment. Therefore, sampling equipment is needed to sample and test the culture fluid during processing. Sampling equipment is usually suitable for chemical industry, research institutes, medical schools and other fields.

[0003] The publication number is CN216484147U, which discloses a liquid sampling device, which utilizes a sampling rod to drive a liquid lifting plate to move vertically, and brings the liquid into a liquid storage tank through a liquid outlet, thereby avoiding direct contact between human hands and the liquid, making the sampling more uniform, and ensuring the accuracy of subsequent analysis. At the same time, the liquid sampling device has a simple structure and is easy to operate. However, in its actual use, the sampling of liquids at different depths is ignored, and only the liquid at the same depth is sampled, resulting in low sampling efficiency and inconvenience in sampling.
