Tunair™ No-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.

The No-Baffle Shake Flask model features a normal throw, similar to a traditional Erlenmeyer flask, ensuring familiar and predictable performance. This flask provides ample space for cultures while maintaining effective aeration and mixing. The absence of baffles allows for smoother agitation, reducing shear stress on sensitive cultures and promoting better cell growth in suspension.

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.

AbsorbMax™ Black Vinyl Sealing Film

• Minimizes background fluorescence and cross talk between plate wells
• Ideal as a back seal for black plates with clear well bottoms for top reading measurements
• Absorbs stray light, reducing the background caused by light scatter
• Protects light sensitive samples from degradation
• Features a single split liner for easy application

Applications

• Fluorescence assays
• Light sensitive sample protection

Temp. Range

• -40°C to +80°C

Film-Sealing Paddles

BrightMax™ Sealing Film

White, light-reflecting, vinyl sealing film designed for use with white microplates.

• The light reflective properties on clear-bottom plates maximize the sensitivity of bioluminescence and chemiluminescence assays in bottom-reading luminometers
• Maximizes intensity and signal-to-noise ratios in luminescence assays
• May be used as a backing matrix for microscopy of punch-out samples for filter plates (e.g. ELISPOT assays)
• Features a single split liner for easy application

Applications

• Luminescence
• Fluorescence
• Microscopy

• -40°C to +80°C

• Borosilicate 3.3 hybex™ glass
• Autoclavable, reusable & breakage resistant
• Permanent enamel graduation markings
• Ideal for shaking, media prep or storage

hybex™ Erlenmeyer Flasks are manufactured from high quality, borosilicate 3.3 glass. A low coefficient of thermal expansion (3.3), provides temperature resistance that is far superior to that of standard lab glass (or soda lime glass). hybex™ glass is designed to withstand high temperatures, making them ideal for shaking applications, media preparation and long-term storage.
The standard Erlenmeyer flasks have permanent, white enamel graduations for volume measurement and a white identification box for marking or coding.

hybex™ Erlenmeyer Flasks with GL45 caps
 
For storage of media and cultures, the capped flasks include an autoclavable polypropylene cap & drip-ring. Optional cap colors are available, as well as PBT material caps for temperature applications up to 180°C. (Threads are standard GL-45 for compatibility with a wide range of cap types from various manufacturers, including phenoic caps, vented caps, etc.)
