Wuxi Nest Cell Culture Flasks TPE Tube (90 cm, 1/4" ID, 7/16" OD), Heat seal, Vent Filter (0.22 μm, 13.8 cm²), Sterile Double Bag Package, 1 pc/pack, 4 packs/case, 4 pcs/case , C10423-DZC090B

Bi-directional transfer cap assembly for 5 L high-efficiency Erlenmeyer (shaker) flasks designed to enable sterile liquid transfer and gas exchange without opening the vessel. The assembly includes an attached thermoplastic elastomer (TPE) external transfer tube and a hydrophobic PTFE vent filter to permit sterile aeration and maintain an aseptic closed system for cell culture or liquid handling in incubators and shakers.

Key Features:

• TPE external transfer tube length: 90 cm
• Tube dimensions: 1/4" internal diameter (ID) and 7/16" external diameter (OD)
• Vent filter: hydrophobic PTFE membrane, 0.22 μm pore size, 13.8 cm² surface area
• Tube connection: heat sealed (welded) to cap, no additional connectors included
• Packaging: sterile, double-wrapped (1 piece per pack; 4 packs per case; 4 pieces per case)

Advantages:

• Enables sterile, closed-system transfer of liquids to reduce contamination risk during sampling or medium exchange
• Hydrophobic 0.22 μm PTFE vent filter provides sterile gas exchange suitable for incubator use
• Pre-attached, heat-sealed TPE tubing simplifies setup and is compatible with tubing welders to maintain aseptic connections
• Packaged double-wrapped and sterilized for immediate use in cell culture workflows
