Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a liquid sampler which is easy to carry. Background Art

[0002] Liquid sampling is one of the most common operations in experiments. It refers to the process of taking representative samples from the target liquid. A liquid sampler is required in the process of liquid sampling.

[0003] Liquids are often stored in liquid tanks. Existing samplers often use sampling spoon barrels or syringes to sample liquids. When the spoon barrel type samples the liquid in the tank multiple times, the liquid is prone to leakage, which may easily cause unnecessary risks. In addition, the spoon barrel sampler is relatively long and inconvenient to carry. Although the syringe sampler is easy to carry, it is limited in length and difficult to sample the liquid in the liquid tank. Utility Model Content
