Description

Technical Field

[0001] This utility model relates to the field of sample preservation technology, and in particular to a sample preservation device for water conservancy testing. Background Technology

[0002] To improve the accuracy of water source sample testing, current methods typically involve on-site collection, followed by bringing the samples back to the laboratory for testing using various precision instruments to more accurately determine the water source data. Current methods generally involve collecting samples in test tubes, storing the tubes in boxes, and then transporting them to the laboratory for analysis.

[0003] Existing preservation devices typically divide the interior into sections to store more samples. While fixing the sample storage tubes, multiple samples can be placed at the same time. However, after the preservation device is divided, it is very inconvenient to access samples in the internal areas due to the limited operating space of the preservation device.
