Description

Technical Field

[0001] The utility model relates to the technical field of silica gel plate auxiliary manufacturing fixing devices, in particular to a thin layer chromatography silica gel plate laying fixing device. Background Art

[0002] Thin layer chromatography silica gel plates are often used in university teaching experiments, such as pharmaceutical and traditional Chinese medicine experimental teaching, organic compound synthesis experiments or extraction and separation experiments of natural effective ingredients of traditional Chinese medicine, to detect the reaction progress, identify the spot reaction or separate and prepare effective ingredients. Thin layer chromatography silica gel plates are widely used in pharmaceutical and traditional Chinese medicine experiments and are frequently used in the experimental process. There are special experimental classes to teach the preparation of thin layer chromatography silica gel plates in teaching experiments. Reusable glass plates are used to let students make silica gel plates by themselves. However, the handmade silica gel plates by students are prone to uneven silica gel coating or bubbles. The dried silica gel plates become uneven or the bubbles formed become small holes after drying, which affects the development and separation. The homemade silica gel plates have poor effects in subsequent experiments.
