The sealing cap on the cell culture bottle is relatively simple. The sealing cap is mainly used for the sealed culture of gas and liquid. Because it is completely sealed, there is no ventilation hole on the bottle cap. It is mainly used in incubators and greenhouses that do not contain carbon dioxide. It can be used under certain conditions and has good sealing, which can prevent the invasion of external bacteria and create a good growth environment for cell reproduction. The cell culture Flask with the breathable cap is mainly used in the environment of carbon dioxide, and the breathable cap is composed of two parts: a breathable film and a bottle cap. Breathable membrane is a new type of polymer waterproof material. In terms of production process, the technical requirements of waterproof and breathable membrane are much higher than that of ordinary waterproof materials; in terms of quality, waterproof and breathable membrane also has the characteristics that other waterproof materials do not have. High temperature resistance, low temperature resistance, corrosion resistance, non-adhesion, high lubrication and other characteristics. The breathable layer of the middle layer of the waterproof breathable membrane is a microporous membrane, which is produced by high-tech principles. The pores are sized to allow water vapor to pass through, but not water molecules, so the product is waterproof and breathable. The breathable cap allows carbon dioxide from the environment to enter the cell culture flask, providing the necessary gas conditions for cell growth.

Cell culture flasks mostly use polystyrene with good strength and plasticity, but the surface of this material is hydrophobic, so it needs to be modified to become hydrophilic before it can be used for adherent cell culture. This modification treatment is called TC treatment.

TC full name: Tissue culturetreated, TC treatment means that the vessel has undergone surface modification treatment and is suitable for the culture of adherent cells. Cells grown in suspension do not necessarily need such specially treated vessels. However, cell culture flasks that have undergone surface modification treatment are generally also suitable for culturing cells in suspension. Surface TC treatment technology is a commonly used treatment method for cell culture flasks and other consumables. When purchasing adherent cell culture consumables, special attention should be paid to whether they have undergone surface treatment to ensure that adherent cell culture methods are met.Purpose of TC TreatedThe difference between sealed caps and vent caps for cell culture flasks.
