Embodiment

[0031] The thin-layer development device is used to enable organic solvents to develop, which is convenient for the test and observation of organic solvents. However, different organic solvents have different viscosities, which will lead to different development speeds when using the same thin-layer development device for different organic solvents. The efficiency of the development of the organic solvent is lower.

[0032] There are three types of existing thin-layer development devices: vertical type, horizontal type and automatic type. Different solvents have different viscosities. In the existing thin-layer development devices, different solvents have different development speeds. The use of a vertical thin-layer development device for large solvents will make the movement time longer, and the use of a horizontal thin-layer development device will cause the solvent to slide down quickly, which cannot be effectively developed in the thin-layer development device, resulting i...

Abstract

The invention provides a thin layer expansion groove and a thin layer expansion device, and relates to the field of biology, wherein the thin layer expansion groove comprises a bottom plate, a first side plate, a second side plate, a third side plate and a fourth side plate, the first side plate, the second side plate, the third side plate and the fourth side plate are all connected with the bottom plate, the first side plate and the second side plate are oppositely arranged, the third side plate and the fourth side plate are oppositely arranged, the bottom plate is provided with a plurality of first clamping grooves, and the first side plate and the second side plate are provided with a plurality of second clamping grooves. According to the thin layer expansion groove and the thin layer expansion device, an organic solvent is rapidly expanded, the speed is accelerated, meanwhile, the expansion effect of the organic solvent is guaranteed, and the condition of uneven expansion is avoided.

Description

technical field [0001] The invention relates to the field of biology, in particular to a thin-layer developing tank and a thin-layer developing device. Background technique [0002] Thin-layer development tank and thin-layer development device are used in thin-layer chromatography technology, thin-layer chromatography, also known as thin-layer chromatography, is a kind of chromatography, and it is an important experimental technique for rapid separation and qualitative analysis of small amounts of substances. Solid-liquid adsorption chromatography combines the advantages of column chromatography and paper chromatography. On the one hand, it is suitable for the separation of a small amount of samples (a few micrograms, even 0.01 micrograms); , Therefore, it can also be used to refine samples. This method is especially suitable for substances that are less volatile or prone to change at higher temperatures and cannot be analyzed by gas chromatography. It is to spread the adso...
