Foxx Life Sciences EZclear Erlenmeyer Shaker Flasks are molded from virgin, optically clear, non-leaching polycarbonate resin. Our flasks retain clarity after gamma sterilization, and comply with stringent and USP requirements. Sterile flasks are additionally certified as non-pyrogenic and DNase/RNase-free, making them ideal for cell cultures, microbial cultures, plants, media preparation, storage, and all other applications. They also fit all standard shaking incubator clamps and can be placed on any platform. Foxx Life Sciences EZclear Flasks are available with a flat or baffled base for increased oxygenation and mixing. Flasks are compatible with all 53mm VersaCap technology and adapter inserts, enabling easy customization of top connections. Vented VersaCap with a 0.2µm hydrophobic membrane can be purchased with the unit, or separately as an accessory. All Flasks and VersaCap are autoclavable at 15 PSI and 121˚C for 20 minutes.
