Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for vitamin detection. Background Art

[0002] A sampling device for vitamin testing is a device used to take samples from a vitamin stock solution. A vitamin stock solution refers to a pure undiluted vitamin solution, which is usually used to prepare vitamin medicines or added to food and beverages. A sampling device for vitamin stock solution testing usually consists of a container and a sampling tube. The container is usually a sealed bottle or container for storing the vitamin stock solution, and the sampling tube is a specially designed tube that can easily take out the required sample from the container. When using the sampling device for vitamin stock solution testing, first shake the vitamin stock solution in the container to ensure that the sample is evenly mixed. Then, insert the sampling tube into the container so that its bottom contacts the vitamin stock solution, and the vitamin stock solution can be sucked into the sampling tube by suction.

[0003] However, some existing vitamin detection sampling devices can usually only meet the needs of one sampling tube for sampling when in use. When the second sampling tube needs to be sampled, it takes a lot of time to replace it, resulting in low overall work efficiency. Therefore, this problem needs to be solved. Utility Model Content
