These flasks are optimally designed for use in all aerobic/anaerobic suspension cultures.

• Autoclavable once
• Virgin, medical-grade resin
• Chemically inert and non-leaching
• Wide temperature tolerance
• Uniform thickness
• Molded-in graduations

These flasks can be used for storage, media preparation, mammalian, microbial, and plant cell culture and related applications.

Flasks are manufactured from virgin, medical-grade resin that retains its clarity after being exposed to gamma radiation. They are inert, non-leaching, and provide a wide temperature tolerance and uniform thickness. They are also tested with E. coli cultures for improved nucleic acid yield. Flasks are available with either a flat or baffled base, and they will fit all standard shaking incubator clamps. Molded-in graduations are included on all sizes.

The 125mL, 250mL, 500mL and 1L flasks are available with a vented cap with a 0.22µm pore-size PTFE membrane for aerobic (sterile air exchange) and a solid cap for anaerobic (no air transfer) applications. The 2L and 3L flasks come with a convenient vented duo cap that makes switching caps easy; simply remove the dustguard cover to allow sterile exchange, and then replace the cover when ready.
