Thermo Scientific Culture Flask Nunc EasYFlask 75 cm2 Nunclon Delta Surface - Case of 100

Thermo Scientific 156499 Nunc EasYFlask 75 cm² (Nunclon Delta, Filter Cap)

The Thermo Scientific 156499 is a premier 75 cm² cell culture flask designed to optimize both cell growth efficiency and laboratory 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 signature EasYFlask design includes a wide-angle, canted neck that allows for total access to the growth surface with pipettes or cell scrapers, significantly reducing the risk of sample loss and cross-contamination. Equipped with a high-performance 0.22 µm filter cap, the flask ensures continuous, sterile gas exchange while maintaining a secure barrier against particulates and microorganisms.

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, from primary cells to immortalized lines.

• Ergonomic EasYFlask Neck: The wide-mouth, angled design provides unobstructed access to the entire growth area. This facilitates rapid media changes and more efficient cell harvesting compared to traditional narrow-neck 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 during incubation.

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

Key Benefits & Applications

• Routine Cell Maintenance: The T-75 format is the universal standard for maintaining and scaling up cell cultures before seeding into larger vessels or multi-well plates.

• Maximum Harvesting Efficiency: The optimized geometry eliminates "dead zones," ensuring that the entire cell monolayer is accessible for enzymatic dissociation or mechanical scraping.

• Incubator Space Optimization: Features a stable footprint and perimeter ridge for secure stacking, maximizing shelf space while ensuring even temperature distribution between flasks.

• Batch Traceability: Each flask is printed with a unique lot number and volume graduations on both sides, ensuring reliable sample tracking and volume verification in regulated environments.
