Description

Technical Field

[0001] The utility model relates to the technical field of accessories for tissue dehydrators, and particularly relates to a self-priming solvent bottle for a dehydrator. Background Art

[0002] Pathologists need to change the liquid of HE stain every day for HE staining. Before HE staining, the samples need to be dehydrated. During the dehydration process using a dehydrator, the solvents commonly used are xylene, formalin, and absolute ethanol. All three are volatile and flammable, and xylene and formalin are toxic.

[0003] Before using the existing dehydrator, the solvent for dehydration needs to be filled into a solvent bottle, and the solvent bottle needs to be installed on the dehydrator. Currently, the solvent bottle is mainly installed manually by staff. Since xylene, formalin, and absolute ethanol are all volatile, when connecting the solvent bottle to the dehydrator, the solvent bottle is opened, and the staff will inevitably come into contact with the three. Over time, it will cause serious damage to the staff's body. Summary of the Utility Model
