Description

Technical Field

[0002] The fraction collection device, i.e., the fraction collector, is a device widely used in the fields of chemistry, biology, and pharmacy. It is used to collect the droplets flowing out of the chromatography column by separating the solution separated from the chromatography tube or column according to preset conditions (such as volume, time, threshold, slope, etc.); Among them, bacteria and enzymes need to be treated at low temperatures when they are distilled. Low temperatures can improve efficiency and make the separation of the mixture on each plate better, because low temperatures will slow down the diffusion rate of the mixture on the plate, making it easier to separate the substances. At the same time, low temperatures can also improve the fractionation effect. When distilling bacteria and enzymes, the temperature needs to be controlled in the range of zero to ten degrees to prevent them from losing their activity. At present, in the process of fraction extraction, batch processing of fractions is inconvenient. In order to maintain the activity of samples, samples need to be collected in a low-temperature environment.

After moving the fraction component 46 to a suitable position, the auxiliary drip rack 463 drives the fraction pipeline 6 to be perpendicular to the test tube opening on the test tube rack 31, and performs fraction processing on one of the test tubes. Subsequently, the third drive motor 47 moves again, so that the transmission belt 44 drives the fraction component 46 to slide on the linear guide rail 45, so that the internal fraction of a group of test tubes is completed. When one group of processing is completed, the signal transmitted by the magnetic induction signal receiver 26 causes the second drive motor 461 on the fraction component 46 to work, so that the output end of the second drive motor 461 drives the auxiliary rod 462 to adjust the angle of the auxiliary drip rack 463, and the auxiliary drip rack 463 guides the fraction pipeline 6 to perform fraction processing on the second group of test tubes on the test tube rack 31.
