Half-Baffle TUNAIR™ Polypropylene Erlenmeyer Flask Kit, 2.5 Liters

TUNAIR™ Half-Baffle Polypropylene Shake Flask System – 2.5 L for High Oxygen Transfer The TUNAIR™ Polypropylene Flask System is a unique and patented flask and closure design, engineered to meet the specific needs of microbiology and biotechnology laboratories. This system creates optimum growth conditions for aerobic microorganisms, mammalian cells, and plant cell cultures. Its advanced design supports enhanced oxygen transfer and nutrient distribution, helping scientists and researchers achieve more productive culture outcomes. TUNAIR™ flasks outperform standard Erlenmeyer flasks by promoting improved culture growth and higher cell yields. This superior performance is due to a proprietary baffling system combined with a precision-engineered turbo-vane closure, which significantly increases the availability of dissolved oxygen. The system’s architecture is tailored to maximize surface aeration, agitation efficiency, and gas exchange—key variables for successful bioproduction and research. Advanced Half-Baffle Design for Efficient Mixing and Growth The Half-Baffle Shake Flask is equipped with two internal baffles that create a vortex mixing effect during orbital shaking. This promotes uniform nutrient distribution, reduces sedimentation, and optimizes mass transfer rates. With a working volume of 1 liter, the flask is ideal for use in high-throughput screening, media optimization, and small-scale bioreactor modeling. Each flask is constructed from chemically resistant polypropylene, allowing it to withstand exposure to a wide range of laboratory solvents. The system includes four 2.5 L Half-Baffle TUNAIR™ Shake Flasks, four two-piece polypropylene cap assemblies, and five 0.22-micron Dri-Gauze filters made from nitrocellulose. These filters are designed for high-efficiency sterile airflow and can be autoclaved up to 10 to 12 times while remaining installed within the cap assembly. While autoclavable, Dri-Gauze filters are not designed to be cleaned and should be replaced after extended use. Reusable, Autoclavable System for Long-Term Lab Efficiency All TUNAIR™ flasks and caps are fully autoclavable and designed for repeated use in sterile culture workflows. Cleaning is simple—just soak the components in water with a mild detergent to loosen particulates or biological residue, then rinse and allow to air dry. This ease of maintenance makes the TUNAIR™ system both time-efficient and cost-effective for long-term laboratory operations. This innovative shake flask system is ideal for life science professionals seeking to improve the scalability and performance of microbial, mammalian, or plant cell culture processes. Its durable construction, optimized oxygen transfer, and high reusability make it a preferred solution in academic research, industrial biotechnology, and pharmaceutical R&D.
