Compared to my previous experiences with other brands, the Corning Falcon consistently outperformed them in terms of cell adhesion and growth rate. The vacuum-gas plasma treatment truly made a difference, leading to more consistent and reproducible results in my experiments. This translated directly into increased efficiency in my research and greater confidence in my data.

Breaking Down the Features of Corning Falcon Tissue Culture Flasks, Sterile, 353139 Canted-Neck Flasks

Specifications

• Growth Area: 225 cm²: This generous surface area allows for culturing a substantial number of cells, ideal for large-scale experiments or long-term cell banks. The larger growth area reduces the need for frequent passaging, minimizing the risk of genetic drift in cell lines.

• Total Volume: 800 mL: The flask can hold a large volume of media, providing ample nutrients and buffering capacity for cell growth. This larger volume is particularly beneficial for slow-growing cell lines or those that consume a significant amount of nutrients.

• Cap Type: Plug-Seal: The plug-seal cap offers a secure closure while allowing for gas exchange, essential for maintaining optimal pH and oxygen levels within the flask. The plug-seal design minimizes the risk of contamination while ensuring adequate aeration for cell respiration.

• Material: High-Quality Polystyrene: The polystyrene construction ensures optical clarity for microscopic examination and provides a stable, non-toxic surface for cell attachment. This material allows for easy visualization of cells under a microscope, enabling researchers to monitor cell morphology and growth patterns.

• Sterilization: Gamma Irradiation: Gamma irradiation guarantees sterility, eliminating the risk of contamination and ensuring the integrity of cell cultures. This method of sterilization is highly effective and leaves no residue that could potentially harm the cells.

• Treatment: Vacuum-Gas Plasma: The Corning Falcon Tissue Culture Flasks, Sterile, 353139 Canted-Neck Flasks are uniquely treated to optimized for consistent growth surface, providing optimum cell attachment and maximum yield. This plasma surface treatment promotes uniform cell attachment and spreading, leading to increased cell proliferation and overall yield.
