Cell culture sampling device

Abstract

The invention relates to a cell culture sampling device, and effectively solves the problems that an existing aseptic sampling method is cumbersome in operation, and the holding cost of an aseptic environment is high. According to technical scheme, the cell culture sampling device comprises an incubator, wherein the incubator is internally and uniformly provided with multiple sampling units at intervals in sequence from left to right, the heights of the sampling units in the incubator are decreased in sequence from left to right, each sampling unit comprises a circular tube, each circular tubeis provided with an axial through groove, the outer side of each circular tube is coaxially and fixedly provided with a superior arc-shaped plate, the front end of each circular tube is provided withan L-shaped tube, an inferior arc-shaped plate is arranged above each L-shaped tube, the rear end of each circular tube is fixedly provided with a rotary plate, the outer circle surface of each rotary plate is provided with a first through hole, the other side of each rotary plate is coaxially provided with a circular ring, the inner circle surface of each circular ring is in slidable adherence connection with the outer circle surface of the corresponding rotary plate, four second through holes are circumferentially and uniformly formed in the corresponding circular ring, and the four secondthrough holes are connected with a high-pressure air source, a disinfection water source, a clear water source and a cell nutrient solution source clockwise in sequence starting from the second through hole located in the upper right end.

Description

technical field [0001] The invention relates to the field of cell sampling, in particular to a cell culture sampling device. Background technique [0002] Cell culture is an important method to study cell biology. During the culture process, some living cells need to be taken out frequently for research and experiments. Since the cells need to be cultured in a constant temperature and sterile environment after isolation, Traditional cell culture is mostly placed in an incubator in a sterile box, and cultured in the incubator. When experimental samples are needed, a part of the cell culture solution is sucked through a straw after a series of disinfection operations for research. This sampling method seems to be Simple but very cumbersome to operate in practice. Frequent aseptic disinfection is also a waste of scientific research time. At the same time, each aseptic disinfection is performed manually. This method has a great risk of causing bacteria to be mixed into the incub...
