According to the actual scenarios and business needs of the customer, MEGAROBO customized the loading tray, which can realize the feeding of the blood sampling tube, scanning the code, connecting to the information system and checking the sample information, weighing, sorting, and transferring to the corresponding testing area. The pipeline layout ensures that the sample tubes are neatly arranged into the carrier. It simultaneously transfers the sorted sample tubes to the follow-up testing area, and automatically completes all sample preparation steps inlcuding centrifugation, decapping, blood stratification testing, hemolysis testing, and sub-packaging of each component, so that the whole process is truly unattended, forming an overall solution for liquid biopsy sample preparation.
