Wuxi Nest Cell Culture Flasks 3 L, Wide Mouth,PC, Vent Cap, Flat Bottom, Sterile，Ultra-low Particulate Triple Bag Package, 1 pc/pack, 4 packs/case, 4 pcs/case , 786519

High-efficiency 3 L polycarbonate (PC) wide-mouth cell culture flask with flat bottom and vent cap for shaker and large-volume cell culture applications. The flask is sterile and designed for suspension and mammalian/insect cell cultures, medium preparation, mixing and storage; its wide-mouth neck improves sampling and filling while the shape maximizes shaker platform use and oxygen transfer to support cell viability and yield.

Key Features:

• Volume: 3 L
• Material: Polycarbonate (meets USP Class VI standard)
• Design: Wide mouth neck, flat bottom (high-efficiency Erlenmeyer shape)
• Cap: Vent cap with 0.2 µm vent membrane (watertight, not airtight)
• Sterilization & cleanliness: E-beam sterilized; DNase/RNase free, non-pyrogenic, ultra-low particulate
• Packaging: Triple bag package, 1 pc/pack, 4 packs/case (4 pcs/case)
• Part code: 786519

Advantages:

• Wide-mouth neck and 3 L volume enable easier sampling, filling and large‑volume cultures to increase throughput.
• Polycarbonate construction (USP Class VI) provides high transparency, impact and oxidation resistance and withstands autoclave temperatures up to 121°C.
• Vent cap with 0.2 µm membrane maintains sterile gas exchange for improved oxygen flux during shaker culture.
• E-beam sterilization, DNase/RNase-free and ultra-low particulate triple-bag packaging reduce contamination risk and support aseptic workflows.
