Description

Technical Field

[0001] The utility model relates to the technical field of teaching devices, in particular to a pigment separation experimental device. Background Art

[0002] In the biology teaching experiments in junior and senior high schools, the extraction and separation experiments of pigments in green leaves are often carried out. The pigments extracted from green leaves are a mixture, including chlorophyll a, chlorophyll b, lutein and carotene. The principle of separating pigments is that the pigments in green leaves can be dissolved in the chromatography fluid, and different pigments have different solubilities in the chromatography fluid. Therefore, pigments with high solubility diffuse quickly on the filter paper with the chromatography fluid, and pigments with low solubility diffuse slowly on the filter paper with the chromatography fluid. Different pigments in green leaves will be separated as the chromatography fluid diffuses on the filter paper.

[0003] However, the existing pigment separation experimental device requires the operator to manually add the chromatography liquid, which is volatile and will affect the health of the operator. At the same time, the filter paper strips become soft after absorbing the liquid, and are prone to contact with each other, affecting the chromatography effect. Utility Model Content
