Description

Technical Field

[0001] This utility model relates to the field of sample storage tube technology, and in particular to an environmental monitoring sample storage tube. Background Technology

[0002] With the acceleration of global industrialization and the continuous growth of population, environmental pollution problems have become increasingly prominent, and people are paying more and more attention to environmental quality. Environmental monitoring work has become increasingly important, covering multiple fields such as air, water and soil. As an essential tool in the process of sample collection, transportation and storage, the role of sample storage tubes cannot be underestimated.

[0003] Early environmental monitoring sample storage tubes were relatively simple, made of glass and sealed with cork or rubber stoppers. When collecting water samples, monitoring personnel would directly immerse the glass tube in water, fill it, and quickly stopper it to retain the sample. This method was simple and inexpensive. However, the sealing performance of cork and rubber stoppers was poor, failing to effectively prevent the sample from exchanging with external substances for extended periods. This led to changes in the sample's composition and properties, severely impacting the accuracy of monitoring results. With the continuous development of environmental monitoring technology, the performance requirements for sample storage tubes have also increased. Existing sample storage tubes use high-strength plastics to enhance their impact resistance; however, the sealing method relies on threaded compression. These threaded connections are prone to loosening during transportation, leading to sample contamination and leakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an environmental monitoring sample storage tube, which aims to improve the problem that the threaded connection in the prior art is prone to loosening during transportation, leading to sample contamination and leakage.
