Description

Technical Field

[0001] This utility model belongs to the field of test tube rack technology, and more specifically, it relates to a multifunctional chemical experiment test tube rack. Background Technology

[0002] Test tube racks are specialized experimental instruments used in fields such as chemistry, biology, and medicine to store, fix, and support test tubes. Their core function is to maintain test tubes in a stable state at a vertical or specific angle through structural design, facilitating experimental operation, observation, or preservation.
