IBI Scientific SS-2012 TUNAIR Half-Baffle Polypropylene Erlenmeyer Flask 300 mL

The TUNAIR™ polypropylene Erlenmeyer 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.

Additional Item Description:

The TUNAIR™'s high oxygen absorption rate is due to the unique baffling and turbo-vane closure design. The TUNAIR™ flask systems are designed to increase the availability of dissolved oxygen as well as improve cell yields.

The Half-Baffle Shake Flask has two baffles that produce a vortex motion.

All TUNAIR™ flasks and caps can be cleaned by soaking in water with a light detergent solution to loosen dirt and contaminants, then air dry.

The flasks are constructed of polypropylene and resistant to most solvents.

300 ml flask:

Allows for approx. 150 ml (max) of working volume for culturing cells

Half-Baffle:

The bottom inside of the flask has 2 raised baffles. This configuration will generate a single vortex within the media inside the flask when fastened to an orbital shaker. The half-baffle configuration will allow for slower operational rpm of the shaker while maintaining the single vortex. Less splashing occurs with the half-baffle flask which results in less cell death and higher cell densities.

Attaching the flasks to your shaker: 

IBI TUNAIR flasks can be used with nearly all standard shakers and shaker clamps. The 300 ml flask typically fits best in the 250 ml shaker clamp.

Preparing and Cleaning the TUNAIR flask: 

Your TUNAIR flasks are constructed of polypropylene plastic which allows them to be autoclaved. Once you have prepared your media inside the flask you can place the cap & filter on the flask and insert into the autoclave. Set the autoclave for wet cycle.

Once you have harvested your cells, wash the TUNAIR flask in a mild dish soap such as Dove Dish Soap then rinse well with DI water. Do NOT rinse the Dri-Gauze filter between uses. Observe the condition of the filters between runs to make certain there are no holes or tears in the filter. If there are, replace the filter immediately.
