Cell culture device for biotechnology research and development

Abstract

The invention discloses a cell culture device for biotechnology research and development. The device comprises an incubator, frame plates, a ventilation module and a sterilizing filtrate tank, whereina plurality of layers of the frame plates are arranged at the inner upper part of the incubator and used for placing cell culture dishes; the sterilizing filtrate box is arranged at the bottom of theincubator; the ventilation module is arranged on the outer surface of the side surface of the incubator; fresh air is introduced into the sterilizing filtrate box by the ventilation module from the outside; internal air is sucked by the ventilation module from the inner top of the incubator and discharged to the outside; a sterilizing liquid is injected into the sterilizing filtrate box; the ventilation module comprises a first filter screen, a second filter screen, a first fan, a second fan, an air inlet pipe, a fresh air pipe, an air return pipe, an exhaust pipe and a path change valve set;the path change valve set is provided with four connectors which are connected with the air inlet pipe, the exhaust pipe, the first filter screen and the second filter screen respectively; and the first filter screen and the second filter screen alternately performs filtering, and a backflow gas cleaning filter screen keeps efficient for a long time.

Description

Technical field [0001] The invention relates to the field of cell cultivation, in particular to a cell cultivation device for biotechnology research and development. Background technique [0002] Cell culture is a very important and widely used technology in the field of biotechnology. Many scientific experiments and research require appropriate cell culture. [0003] During the cell culture process, cells will also undergo metabolism. If the metabolites are not discharged in time, it will affect the cell growth environment. Many cell culture gas environments use air components, but dust and bacteria removal operations are required. Otherwise, Dust and bacteria falling on the cell strain will affect the growth of cells. Therefore, how to perform efficient air replacement and sterilization and dust removal of the cell incubator are the key points in the design of cell culture devices. In addition, many cell incubators are large and Because the cell growth environment generally need...

Problems solved by technology

[0003] During the cell culture process, the cells also undergo metabolism. If the metabolites are not discharged in time, it will affect the growth environment of the cells. Many cell culture gas environments use air components, but dust and bacteria removal operations are required. Otherwise, Dust and bacteria falling on the cell strains will affect the growth of the cells. Therefore, how to perform efficient air replacement and sterilization and dust removal in the cell incubator is the design point of the cell cultivation device. In addition, many cell incubators are large and Because the growth environment of cells generally needs to be "greenhouse conditions" higher than the air temperature, if the gas in the incubator is directly discharged out of the device during the ventilation process, a large amount of heat will be lost, and additional high-power heating is required Heater for fresh and clean air heating operation, energy utilization is inefficient
