Description

Technical Field

[0001] The utility model relates to the technical field of sample extraction, in particular to a sample extraction device for sunscreen lotion detection. Background Art

[0002] Sunscreen is a skin care product whose main function is to protect the skin from ultraviolet rays and prevent the formation and accumulation of melanin by using the sunscreen principle. It achieves the effect of sun protection by forming a protective layer on the surface of the skin, effectively isolating the sun from contacting the skin.

[0003] During the production process, each batch of newly produced sunscreen needs to undergo rigorous sample extraction and testing to ensure that the product quality meets the standards before it can be put on the market. However, existing sample extraction devices can usually only perform a single extraction, which limits work efficiency to a certain extent.

[0004] If you need to analyze different ingredients in sunscreen multiple times, or if you need to repeat the experiment to ensure the accuracy and reproducibility of the experimental results, you need to extract the same sample multiple times. Obviously, a single extraction device cannot meet this need. Utility Model Content
