Description

Low-adsorption sample preservation tube Technical Field The utility model relates to the technical field of preservation pipes, in particular to a low-adsorption sample preservation pipe. Background Low adsorption samples generally refer to samples having a low tendency to adsorb on a particular surface or material, and such samples are characterized by being less prone to physical adsorption, chemical binding or interaction when in contact with a container, pipe, instrument, etc., thereby reducing sample loss, contamination or denaturation, and the core of the low adsorption samples is to reduce the interaction of the sample with the contact surface, which is commonly used in the fields of biology, chemistry, pharmacy, etc., and can effectively reduce the loss or contamination caused by adsorption by selecting suitable materials (e.g., PTFE, siliconized glass), surface treatment or optimizing experimental conditions. In the prior art, as the low adsorption sample is required to be placed into the preservation pipe for storage, and the bottom of the conventional preservation pipe is designed to be of a semicircular cambered surface structure, when the preservation pipe is required to be independently erected on a tabletop, the preservation pipe is difficult to stably stand due to small contact surface at the bottom, high gravity center and lack of an effective limiting structure, the independent use efficiency and scene adaptability of the preservation pipe are obviously reduced due to the fact that the preservation pipe is required to depend on auxiliary support of an external placement rack, the preservation pipe cannot be independently placed in a scene without a placement rack, such as a temporary experiment table and a field environment, supports are required to be additionally found or operation is interrupted, and experimental continuity is reduced.
