Description

Technical Field

[0001] The utility model relates to the technical field of chromatography equipment for Chinese herbal medicine extracts, in particular to a Chinese herbal medicine extract reprocessing chromatograph. Background Art

[0002] According to the patent document with the publication number CN218011198U, the sample is temporarily stored through the valve on the chromatography tube, and the turntable is rotated to select the test tube of the corresponding size according to the amount of the sample, and the collected sample is introduced into the corresponding test tube;

[0003] When collecting samples, the patent document generally uses test tubes of different sizes, and the overall heights of the test tubes are not the same, so the distances from the conical tube and the hose at the bottom of the chromatography tube to each test tube are also different; for a large test tube, the hose of the chromatography tube will be located at its tube mouth, while for a small test tube at the same position, the hose of the chromatography tube will be higher than its tube mouth, and if the whole is shaken, the sample will be spilled; when collecting samples, the entire turntable is completely rotated manually, and it is more convenient for large test tubes to correspond to the chromatography tubes, while for small test tubes, there is a certain distance between the hose at the bottom of the chromatography tube and the small test tube, and since the diameter of the small test tube is smaller, it will be inconvenient to correspond to the chromatography tube.
