IBI Scientific SS-6003S TUNAIR Full-Baffle Polypropylene Erlenmeyer Flask Kit 2.5 L w/ Silicone Filters

TUNAIR™ Polypropylene Erlenmeyer Flask Systems: Optimized for Superior Growth

The TUNAIR™ Polypropylene Erlenmeyer Flask systems by IBI Scientific are a unique and patented solution, specifically designed for microbiology and biotechnology applications. These flasks provide optimal growth conditions for aerobic microorganisms, mammalian cells, and plant cells, outperforming standard Erlenmeyer flasks in both culture growth and productivity. The high oxygen absorption rate is achieved through the innovative baffling and turbo-vane closure design, enhancing the availability of dissolved oxygen and improving cell yields. Each Full-Baffle Shake Flask, with a working volume of 1 L, features six baffles that create a propeller motion, ensuring efficient mixing and aeration.

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. The Full-Baffle Shake Flask has six baffles that produce a propeller motion.

The two piece cap assemblies are constructed of polypropylene and are resistant to most solvents. All flasks and caps are fully autoclavable prior to reuse and filter linings can also be autoclaved or simply replaced.

Other Product Details:

• Comes complete with 4 polypropylene 2.5 L Full-Baffle TUNAIR™ Shake Flasks, 4 two-piece caps, and 5 silicone filters.

Filter Replacement:

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 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.

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.

2.5 L flask:

Allows for approx. 1 L (max) of working volume for culturing cells

Full-Baffle:

The bottom inside of the flask has 6 raised baffles. This configuration will generate 4 small propeller vortexes within the media inside the flask when fastened to an orbital shaker. The full-baffle configuration allows for slower operational rpm of the shaker while maintaining the vortexes within the media. The full-baffle flask is ideal for growing E.coli providing superior growth rates and cell densities. The 2.5 L flask has a special cap and filter system that promotes gas exchange and maintains sterility of the growth culture during use. The inner portion of the cap unsnaps from the outer portion by pushing in the tabs on the side of the cap assembly and then pulling the insert out.

Two Piece Cap:

The 2.5 L flask has a special cap and filter system that promotes gas exchange and maintains sterility of the growth culture during use. The inner portion of the cap unsnaps from the outer portion by pushing in the tabs on the side of the cap assembly and then pulling the insert out.

0.2-micron filters: 

Silicone- This is a silicone filter that will last the life of the flask. This filter can be autoclaved while in the cap and on the flask for many times.

Cap & Filter assembly: 

Once you have the 2-piece cap assembly apart place the corresponding filter size inside the cap and the re-assemble the inner and outer cap pieces making certain to align the tabs with their associated holes. Once clipped into place, make certain the filter completely covers the cap assembly openings. 

Attaching the flasks to your shaker: 

IBI TUNAIR flasks can be used with nearly all standard shakers and shaker clamps. The 2.5 L flask typically fits best in the 2 L 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. The silicone filter can also be rinsed with DI water if needed. 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.
