Falcon Culture Flask 750 ml with Plug Seal Cap 175 cm2 40 Flasks

Falcon 353028 175 cm² Cell Culture Flask (TC-Treated, Plug Seal Cap)

The Falcon 353028 is a high-capacity, 175 cm² cell culture flask engineered for the reliable expansion of anchorage-dependent mammalian and insect cell lines. Manufactured from crystal-grade virgin polystyrene, this flask features a vacuum-gas plasma Tissue Culture (TC) treatment that ensures a consistent, hydrophilic surface for optimal cell attachment and uniform monolayer formation. Equipped with a versatile Plug Seal Cap, the flask allows for both open-system incubation (via the "vent" position) and a secure, liquid-tight seal for closed-system culture or sample transport. Its robust, stackable design makes it a staple for large-scale bioprocessing, vaccine research, and protein expression.

Technical Performance and Design

• Validated TC-Treated Surface: The proprietary vacuum-gas plasma treatment provides a stable, negatively charged surface chemistry that promotes rapid cell attachment, spreading, and high-density growth kinetics.

• Dual-Position Plug Seal Cap: The chemically resistant HDPE cap can be turned to a partial "open" position for controlled gas exchange during incubation, or tightened to a secondary stop to create a leak-proof, airtight seal.

• Canted Neck Geometry: Designed with an angled neck to allow for unobstructed pipette access and easier cell harvesting with scrapers, minimizing "dead zones" and maximizing sample recovery.

• Exceptional Optical Clarity: The high-quality polystyrene walls provide a clear, distortion-free view for inverted microscopy, allowing for easy monitoring of cell morphology and confluence.

Key Benefits & Applications

• Large-Scale Cell Expansion: The 175 cm² surface area is optimized for high-yield harvests required for downstream RNA/DNA isolation, Western blotting, or seeding into bioreactors.

• Closed-System Incubation: The plug seal cap is essential for experiments where a specific gas mixture must be maintained inside the flask or when using incubators that do not provide CO2 regulation.

• Safe Sample Transport: Provides a secure, leak-proof vessel for moving live cell cultures between laboratories or for short-term storage without the risk of environmental contamination.

• Structural Integrity: Features reinforced sidewalls and a stable footprint designed for stacking, ensuring maximum space efficiency within standard laboratory incubators.
