Tunair™ Half-Baffle Flasks and Kits

Tunair™ Erlenmeyer Flask Systems by IBI Scientific are an innovative solution designed to enhance the growth and productivity of microbial, mammalian, and plant cell cultures. Engineered specifically for microbiology and biotechnology applications, these flasks outperform traditional Erlenmeyer flasks by offering superior oxygen absorption rates, efficient aeration, and optimal mixing. Whether used in academic research, industrial bioprocessing, or pharmaceutical production, Tunair™ flasks provide an exceptional environment for aerobic cultures, ensuring higher cell yields and improved growth conditions.

Tunair™ half-baffled flasks feature two internal baffles that generate a swirling motion, maximizing liquid-air interaction. This vortex effect significantly increases oxygen transfer rates, making it ideal for cultures that require high oxygen availability. The flask design promotes uniform mixing and improved microbial growth, ensuring optimal conditions for fermentation and cell culture applications. In addition to the baffled flask design, the turbo-vane cap closure further enhances aeration by maintaining consistent airflow while preventing contamination.

All Tunair™ flasks and caps are constructed of chemical-resistant polypropylene and are fully autoclavable. To clean flasks and caps, soak them in water with a mild detergent solution. Once cleaned, air-dry all components before autoclaving for complete sterilization.

Applications

• Microbial Fermentation: Ideal for yeast, bacteria, and fungal cultures, where high oxygen demand is essential
• Mammalian and Plant Cell Cultures: Supports delicate cell lines, ensuring high viability and productivity
• Biopharmaceutical Research: Used for vaccine development, protein expression, and monoclonal antibody production
• Academic and Industrial Biotechnology Labs: Suitable for R and D, pilot-scale, and large-scale production 

Tunair™ Flask Caps - Low Profile and Two-Piece Flask Cap Assemblies

Low Profile Flask Cap Assembly

Designed to fit into nearly all manufacturers' shakers, this flask cap measures only 11 In. in height, making it an excellent choice for space-saving applications. The Quick-Flip feature allows for easy and secure filter replacement, minimizing contamination risks. Constructed from polypropylene, the cap is resistant to most solvents. Flask cap is fully autoclavable, allowing for easy sterilization.

Two-Piece Flask Cap Assembly

Constructed from polypropylene, the cap is resistant to most solvents. These flask caps provide an effective seal while allowing proper gas exchange, making them essential for maintaining optimal culture conditions. Designed for repeated use, all flasks and caps are fully autoclavable, ensuring sterility between uses. Available in 300 mL and 2.5-liter sizes.

Tunair™ Cap Linings - Dri-Gauze Filter and Silicone Membrane Linings

Dri-Gauze Filter Cap Linings

Sterility control with 0.2-micron filtration that prevents contamination while allowing optimal gas exchange. They are reusable and cost-effective since each filter can be autoclaved up to six to eight times while remaining inside the flask cap assembly.

Silicone Membrane Cap Linings

Sterility control with 0.22-micron filtration that prevents contamination while allowing optimal gas exchange. Can withstand repeated autoclaving, designed to last for the lifetime of the flask. High flexibility ensures a proper fit within cap assemblies, reducing the risk of leaks or contamination.
