Thermo Scientific Culture Flask EasYFlask Nunclon Delta 175 cm2 Total of 30 Flasks

Thermo Scientific 159910 Nunc EasYFlask 175 cm² (Nunclon Delta, Filter Cap)

The Thermo Scientific 159910 is a premium 175 cm² cell culture flask designed to maximize growth efficiency and user ergonomics. Featuring the proprietary Nunclon Delta surface treatment, this flask provides a consistent, hydrophilic environment that promotes superior attachment and expansion of adherent mammalian cell lines. The unique EasYFlask design incorporates a wide-angle, angled neck that provides full access to the growth surface for both pipettes and cell scrapers, reducing the risk of sample loss. Equipped with a high-performance filter cap, the flask ensures continuous, sterile gas exchange while providing a secure barrier against contaminants, making it ideal for high-stakes biopharmaceutical research and clinical production.

Technical Performance and Design

• Nunclon Delta Surface Treatment: A biological-grade surface modification that ensures consistent cell growth, morphology, and high-density attachment for a wide range of cell types.

• Ergonomic EasYFlask Neck: The wide-mouth, angled design allows for unobstructed access to the entire growth area, facilitating easier media changes and more efficient cell harvesting compared to traditional flask designs.

• Vented Filter Cap: Features a 0.22 µm hydrophobic membrane that allows for constant, uniform gas exchange (CO2/O2) while maintaining a sterile environment and preventing internal pressure buildup.

• Quick-Turn Cap System: Designed for speed and safety, the cap allows for a secure "one-third turn" opening and closing, reducing wrist strain during high-volume processing in the laminar flow hood.

Key Benefits & Applications

• Scale-Up Cell Culture: The 175 cm² surface area is the ideal mid-to-large scale format for producing significant cell yields for protein expression, viral vector production, or vaccine research.

• Maximum Harvesting Efficiency: The lack of "dead zones" in the flask geometry ensures that nearly 100% of the cell monolayer can be reached and detached, ensuring highly accurate yield calculations.

• Stackable Design: Engineered with a perimeter ridge for stable stacking in the incubator, maximizing precious shelf space while ensuring uniform heat distribution.

• Certified Quality: Every lot is tested for sterility, toxicity, and cell attachment to meet stringent pharmaceutical and academic research standards.
