[0003] Centrifuges are usually used for microbial testing and separation. However, during the use of traditional centrifuges, the test tubes storing microorganisms may not be tightly covered due to human operating errors, which may cause the microorganisms inside to spill during centrifugation, thereby interfering with the quality of the inspection work.
