[0002] Cell flasks are cell culture flasks. The main function of cell culture flasks is to provide an ideal in vitro culture environment, allowing cells to grow, reproduce and differentiate under artificial conditions. This environment simulates the physiological conditions of cells in the body and provides the necessary living conditions for cells by controlling parameters such as temperature, humidity, and gas exchange.

[0003] In biological research, cell culture flasks allow scientists to conduct in-depth studies on cell growth patterns, metabolic pathways, signal transduction and other mechanisms. Through long-term, continuous observation and experiments on cells, scientists can reveal the mysteries of many life phenomena and provide important theoretical support for the development of life sciences. Cell culture flasks generally need to be ventilated, so a hydrophobic membrane is set on the bottle stopper to prevent external water molecules from entering the bottle and affecting cell growth while ensuring ventilation. However, there are also cases where the bottle needs to be kept airtight, and in this case, the bottle cap needs to be replaced, which is inconvenient. Utility Model Content
