- Flasks and caps are constructed of chemical resistant polypropylene
- All flasks and caps are fully autoclavable
The TUNAIR™ Shake Flask Systems are a unique and patented flask and closure system, designed for microbiology and biotechnology applications. This system provides optimum growth conditions for aerobic microorganisms, mammalian cells, and plant cells. They also provide better culture growth and productivity than standard Erlenmeyer flasks. The TUNAIR™’s high oxygen absorption rate is due to the unique baffling and turbo-vane closure design. The TUNAIR™ systems are designed to increase the availability of dissolved oxygen as well as improve cell yields. There are three (3) flask designs available depending on your application; the No-Baffle (normal throw), the Half-Baffle (vortex motion), and Full-Baffle (propeller motion). The slip on cap and filter linings protect the flask neck from airborne particles and eliminates the need for flaming. All TUNAIR™ flasks, caps, and linings can be sterilized by autoclaving.
The two-piece cap assemblies are constructed of polypropylene, and are resistant to most solvents. All caps and flasks are fully autoclavable prior to reuse, and filter linings can also be autoclaved or simply replaced. To replace the filter lining in the cap assembly simply pinch the flanges of the inner-closure shell until they snap loose, then pull apart and remove used lining. Replace the lining by sandwiching it between the two parts of the cap and snap the cap back together. When reassembling the cap, ensure the flanges from the inner piece snap into the mated grooves in the outer piece. This will ensure the cap assembly stays together during use.
TUNAIR™ flasks were compared to conventional flasks using four different types of microorganisms; Escherichia coli, Saccharomyces cerevisiae, Penicillium avellaneum, and Streptomyces chartreusis. The aeration capacities of the shake flasks were determined by the sulfate oxidation method, and the values shown below are presented as oxygen absorption rate (OAR) in mM oxygen/L/Min. The growth rates of E.coli and S.cerevisiae were expressed as optical densities (OD) at 555mM. For S.chartreusis and P. avellaneum growth rates were evaluated by percent sedimentation. For E.coli and S.cerevisiae, the growth rates were determined after an 18 hour incubation period; for S.charteusis, a 24 hour incubation period; and for P. avellaneum, a 72 hour incubation period. Growth and OAR evaluations were carried out with 3-9 replicates and statistically analyzed using Turkey’s w-procedure.
All TUNAIR™ flasks and caps can be cleaned by soaking in water with a light detergent (e.g. Joy) solution to loosen dirt and contaminants, air dry. All TUNIARTM flasks and caps can be autoclaved, if required.
All IBI TUNAIR™ filter linings are 0.22 micron, and are available in silicone or nitrocellulose membranes.
