- Closure: The flask features a vented closure, allowing for gas exchange while maintaining a sterile environment. This is crucial for cell culture, as it allows cells to breathe while preventing contamination.
- Baffled Bottom: The baffled bottom of the flask increases the surface area for gas exchange and promotes efficient mixing. This is particularly important for suspension cultures, where cells need to be kept in constant motion.
- Sterility: Each flask is individually packaged and sterilized, ensuring a contamination-free environment for cell culture. This saves time and resources by eliminating the need for autoclaving before use.
- Packaging: The flasks are sold in cases of 4. This makes them suitable for high-throughput screening and large-scale cell culture applications.
These specifications are critical because they directly impact the flask’s performance and usability. The PETG material ensures durability and chemical resistance, while the baffled bottom and vented closure optimize cell growth conditions. The sterility of the flask eliminates the risk of contamination.
Performance & Functionality
The Nalge Nunc Flask Petg 2.8L Baff Vent CS4 4116-2800 excels in its primary function: supporting cell culture in a sterile and efficient manner. The baffled bottom significantly improves aeration and mixing, leading to enhanced cell growth and higher yields. The vented closure effectively prevents contamination while allowing for necessary gas exchange.
One of its key strengths is its convenience. The pre-sterilized, disposable design eliminates the need for washing and autoclaving, saving valuable time and resources.
