Description

Technical Field

[0001] This utility model relates to the field of thin-layer chromatography colorimetric boxes, specifically a laboratory-specific thin-layer chromatography colorimetric box. Background Technology

[0002] Thin-layer chromatography (TLC) involves coating a suitable stationary phase onto a glass plate, plastic, or aluminum substrate to form a uniform thin layer. After spotting and development, the ratio shift (Rf) is compared with the Rf of a suitable reference chromatogram obtained using the same method. This method is used for drug identification, impurity detection, or content determination. In TLC experiments, the colorimetric reagent is sprayed onto a metal stand placed in a fume hood, covered with paper, and the thin-layer plate is placed on the paper against the metal stand before the colorimetric reagent is sprayed directly. However, the metal stand rod is thin, making the thin-layer plate prone to slipping. Furthermore, the colorimetric reagent easily sprays onto the lab bench, making it difficult to clean, and the reagent odor significantly affects the use of the fume hood, causing certain adverse effects on the user experience. Therefore, we propose a laboratory-specific TLC colorimetric chamber. Utility Model Content

[0021] This embodiment is a laboratory-specific thin-layer chromatography colorimetric box.

[0022] like Figure 1-4As shown, the device includes a color developing box 1. A control panel 2 is located on the upper part of the outer surface of the front end of the color developing box 1. A thin sheet 3 is located inside the color developing box 1. A placement mechanism 4 is located at the lower end of the thin sheet 3. The placement mechanism 4 includes a bracket 5, an anti-slip plate 6, an exhaust fan 7, a fixing frame 8, a first limiting groove 9, a T-shaped pull plate 10, a frame 11, a filter plate 12, an odor-removing plate 13, a side plate 14, a rubber pad 15, a slot 16, a locking plate 17, a limiting block 18, a second limiting groove 19, a spring 20, and a slot 21. The exhaust fan 7 is located in the middle of the upper outer surface of the color developing box 1, and the bracket 5 is located on the lower inner surface of the color developing box 1. On the surface, the anti-slip plate 6 is located on the upper outer surface of the bracket 5. The inner wall of the color developing box 1 is provided with an acid-resistant, alkali-resistant, and corrosion-resistant layer. Two sets of fixing brackets 8 are located on both sides of the upper outer surface of the color developing box 1. The first limiting groove 9 is opened at the lower end of the outer surface of one side of the fixing bracket 8. The hole groove 21 is opened in the middle of one side of the upper outer surface of the fixing bracket 8. The T-shaped pull plate 10 is located in the middle of the hole groove 21. The clamping plate 17 is located on the lower outer surface of the T-shaped pull plate 10. The spring 20 is located at the lower end of the outer wall of the T-shaped pull plate 10 and is located between the clamping plate 17 and the fixing bracket 8. The limiting block 18 is located at the upper end of the outer surface of one side of the clamping plate 17.

[0023] The second limiting groove 19 is located at the upper end of the middle of the outer surface of one side of the first limiting groove 9. The frame 11 is located on the upper outer surface of the color developing box 1. The two sets of side plates 14 are located at the lower ends of the outer surfaces of both sides of the frame 11. The rubber pad 15 is located on the lower outer surface of the side plate 14. The slot 16 is located in the middle of the upper outer surface of the side plate 14.
