Sterile 250mL polycarbonate flask without baffles. Virtually unbreakable Lexan (registered trademark of GE Plastics) polycarbonate is used in the manufacture of this product.

Flask comes sterile via gamma irradiation, packaged in its own protective bag with two polypropylene 38mm closures. One is a standard leakproof closure. The other is a vented closure with a PTFE membrane, 0.22um pore size for sterile air exchange.

The polycarbonate is autoclavable which makes for repeated reuse of the flasks. They are certified non pyrogenic and DNase/RNase free for convenience. Product fits all standard shaking incubator slamps and are ideal for culture, media preparation, storage and any related application.

Flasks-Erlenmeyer (PETG)

Solid Cap, Plain Bottom, PETG, Sterile

• Designed for mammalian suspension culture applications as well as bacterial & yeast culture
• Packaged sterile in individual bags for easy storage and handling
• Manufactured from medical grade virgin PETG which reduces gas permeability

• Polypropylene (PP) or polycarbonate (PC)
• Autoclavable (flasks, caps, and filters)
• 0.22µm filters (silicone membrane or dri-gauze)
• Multi-colored caps
• 3 flask designs with different baffle options

TUNAIR flasks present an improved methodology for the growth of aerobic microorganisms as well as mammalian, insect, and plant cells. These flasks increase culture growth (up to 3X for yeast), and increase productivity over traditional Erlenmeyer flasks. The unique baffling and barrel-shape design increase the turbulence, with a corresponding increase in oxygen absorption. TUNAIR flasks are a unique, high-aeration, reusable cell growth system which increase the availability of dissolved oxygen and improve cell yields. Available in either 300ml or 2.5L sizes.

Baffle options:

No baffle, NO-BAF (normal throw)

2 baffles, HAF-BAF (vortex motion)

3 baffles, FUL-BAF (propeller motion)
