  In modern life science research, Cell Culture Flasks , as fundamental laboratory consumables, directly impact the reliability of experimental results. Particularly for adherent cell culture, the surface treatment technology of these flasks is crucial. TC treatment, as the current mainstream surface modification technology, provides an ideal growth environment for cell culture. Scientific Principles and Mechanisms of TC Treatment The core of TC treatment technology lies in altering the surface properties of materials. Traditional polystyrene Cell Culture Flasks exhibit hydrophobic surfaces with contact angles typically above 80°, which is unfavorable for cell adhesion and spreading. Through TC treatment, the material surface is oxidatively modified, reducing the contact angle to 55°–65° and creating a hydrophilic surface. This change allows the culture medium to spread evenly, providing cells with a more uniform growth substrate. The treatment process also introduces an appropriat...

  In cell culture experiments, a sterile environment, precise control of gas and pH levels, and suitable osmotic pressure are all essential conditions for the healthy growth of cells. In large-scale cell culture applications such as vaccine preparation and monoclonal antibody production, the cell factory plays a critical role due to its efficiency and stability. However, the quality of the cell factory directly impacts the growth state of the cells, making strict quality control particularly crucial. The hemolysis test, as an important component of quality inspection for cell factories, aims to evaluate the potential impact of their materials on blood cells. When cells come into contact with the surface of the device or are exposed to material extracts, hemolysis may occur—a phenomenon where the cell membrane ruptures, leading to the leakage of intracellular contents. This not only damages cell health but may also disrupt the entire cell culture process. In accordance with interna...
