AI Technical Summary
Existing environmental monitoring sample storage tubes are fragile and easily break during transportation, causing samples to spill, posing pollution and safety hazards, and are also inconvenient to use.
The design features an externally threaded protective tube and an internally threaded cap. The internal and external threads are connected by a rubber shock-absorbing liner and a round-headed pin structure with magnetic attraction, which improves stability and provides impact protection. The internally threaded cap and the externally threaded protective tube can be separated for easy sample transfer.
It effectively prevents samples from breaking during transportation, improves transportation stability and ease of use, ensures sample safety and no contamination, and simplifies the sample transfer process.
