Here are common uses for a baffled culture flask with a membrane screw cap (long neck):

1. Cell Culture: Baffled culture flasks are designed for cell culture applications, providing a controlled environment for the growth and propagation of cells. The baffles inside the flask promote better mixing and aeration of the culture medium.
2. Adherent and Suspension Cell Lines: These flasks are suitable for both adherent and suspension cell lines. The baffles help prevent the formation of stagnant areas, ensuring efficient nutrient and gas exchange for the cells.
3. Enhanced Oxygen Transfer: The baffled design facilitates improved oxygen transfer within the culture medium. This is particularly beneficial for demanding cell cultures that require higher levels of aeration.
4. Reduced Shear Stress: The baffles help reduce shear stress on cells, making these flasks suitable for delicate cell lines that are sensitive to mechanical forces.
5. Large-Scale Cell Expansion: Baffled culture flasks with a larger volume are often used for large-scale cell expansion and production. The long neck and screw cap provide easy access for adding or removing media and cells.
6. Cell Proliferation Studies: Researchers use these flasks for cell proliferation studies, where they monitor and analyze the growth rate of cells over time.
7. Bioprocessing and Biomanufacturing: Baffled culture flasks are employed in bioprocessing and biomanufacturing applications, especially when scaled-up cell cultures are required for the production of biological products.
8. Virus Production: These flasks may be used in the production of viruses for research or vaccine development. The baffled design helps optimize virus yields.
9. Perfusion Cell Culture: The baffled flask design is suitable for perfusion cell culture systems where continuous nutrient supply and waste removal are crucial for sustained cell growth.
10. Long-Term Cultures: The long neck and screw cap design facilitate long-term cell cultures by allowing convenient access to the culture without disturbing the cells.
11. Gas Exchange and CO2 Incubation: The membrane screw cap provides a gas-permeable barrier, allowing efficient gas exchange and compatibility with CO2 incubators commonly used in cell culture laboratories.
