Description

Technical Field

[0001] The utility model relates to the field of biochemical experiments, and more specifically to a test tube with a cover that can be opened with one hand. Background Art

[0002] Test tubes are indispensable experimental equipment in scientific experiments, medical tests, and chemical analyses. Traditional test tube designs usually require an opening and closing action, which often requires the use of both hands to operate. However, during experiments or tests, experimenters often need to use multiple instruments or perform multiple operations at the same time, so the flexibility and availability of both hands are essential. In order to meet the needs of experimenters in busy experimental environments, one-handed test tubes came into being. This design aims to enable the opening and closing of test tubes with a simple one-handed operation, greatly improving work efficiency and convenience. Although the existing one-handed opening test tube design achieves one-handed operation, it still needs to be improved in terms of sealing, durability, and ease of use, and cannot meet usage requirements.
