Dri-Gauze Filter Cap Linings (Flask) - 5 Pack

Dri-Gauze Filter Cap Linings – Sterile and Reusable Filtration for Flask Applications

The Dri-Gauze Filter Cap Linings are an essential component for laboratory flask applications, offering superior gas exchange while maintaining sterility. Designed for use with TUNAIR flasks, these gauze filters allow for controlled airflow while preventing contamination. Whether you're working with bacterial cultures, fungal propagation, or cell growth, these high-quality filter cap linings help maintain an optimal environment.

Our Dri-Gauze Filter Cap Linings are specifically engineered for a 300 ml flask and provide a reliable 0.2-micron filtration. These filters can be autoclaved multiple times, making them a cost-effective and sustainable solution for research and industrial applications. In addition to the standard paper filter option, we also offer a silicone variant for enhanced durability and flexibility.

Reliable and Reusable Gauze Filter for Laboratory Use

One of the key benefits of using our gauze filter cap linings is their reusability. Each filter can be autoclaved six to eight times while remaining inside the flask cap assembly. This ensures ease of sterilization without compromising structural integrity or effectiveness. Unlike disposable filter options, the Dri-Gauze Filter Cap Linings reduce waste while maintaining high performance over multiple uses. To maintain effectiveness, the filter should be carefully inspected between uses. If any holes or tears are observed, immediate replacement is recommended to prevent contamination. While the gauze filter should not be rinsed between uses, the silicone version may be cleaned with deionized (DI) water if needed.

Cap and Filter Assembly Instructions

The Dri-Gauze Filter Cap Linings are designed for seamless integration with a two-piece cap assembly. Whether using the 300 ml cap or the 2.5 L cap, proper installation ensures optimal filtration efficiency. To assemble, disassemble the two-piece cap assembly, insert the corresponding gauze filter size into the cap, and align the inner and outer cap pieces, ensuring the tabs are properly positioned in their respective slots. Securely clip the cap together, verifying that the filter fully covers the cap openings. This simple yet effective assembly method guarantees uniform airflow while maintaining sterility within the flask.

Preparing and Cleaning TUNAIR Flasks with Gauze Filters

TUNAIR flasks are constructed from durable polypropylene plastic, allowing them to withstand repeated autoclaving. Proper preparation and cleaning procedures ensure the longevity of both the flask and the gauze filter cap linings. Once the desired media has been added to the flask, securely attach the cap and gauze filter. Place the assembled flask into the autoclave and set it to a wet cycle. Autoclaving the gauze filter within the cap ensures that sterility is maintained without compromising the integrity of the filter.

After cell harvesting, wash the TUNAIR flask with a mild dish soap, such as Dove Dish Soap, and rinse thoroughly with DI water to remove any residual media or contaminants. The Dri-Gauze filter should not be rinsed or exposed to excessive moisture outside of the autoclave process. For silicone filters, a DI water rinse is permitted if necessary. Regular inspection of the gauze filter between autoclaving cycles ensures continued performance and contamination control. If any visible damage is detected, replacement is required before the next use.
