Falcon Culture Flask 70 ml with Canted Neck and Vented Cap PS Case of 100 Flasks

Falcon 353109 25 cm² Cell Culture Flask (TC-Treated, Vented Cap)

The Falcon 353109 is a precision-engineered T-25 flask designed for the reliable cultivation of adherent mammalian and insect cell lines. Featuring a vacuum-gas plasma Tissue Culture (TC) treatment, the flask provides a consistent, hydrophilic growth surface that promotes superior cell attachment and uniform monolayer formation. Equipped with a specialized vented cap containing a 0.22 µm hydrophobic membrane, this flask allows for continuous, sterile gas exchange while providing an effective barrier against aerosol contaminants. Manufactured from high-clarity virgin polystyrene, the 353109 is an essential tool for small-scale cell expansion, primary culture initiation, and routine laboratory maintenance.

Technical Performance and Design

• Vacuum-Gas Plasma TC Treatment: The growth surface is permanently modified to ensure a consistent chemistry, leading to reproducible cell attachment and growth kinetics across different lots.

• 0.22 µm Vented Cap: The integrated hydrophobic filter ensures consistent CO2 and O2 exchange while preventing the entry of bacteria, fungi, and other contaminants, even when the cap is fully tightened.

• Canted Neck Design: Features a slanted neck that facilitates easy pipette and cell scraper access to the growth surface, reducing the risk of sample loss and "dead spots."

• High Optical Clarity: The crystal-grade polystyrene construction provides an unobstructed view of the cell monolayer for high-resolution microscopic examination.

Key Benefits & Applications

• Primary Culture Initiation: The small 25 cm² format is ideal for the initial seeding of primary cells or rare samples where high cell density is required for successful outgrowth.

• Scale-Up Pre-Workflow: A standard tool for maintaining seed stocks before scaling up to larger T-75 or T-175 flasks for production.

• Stackable and Stable: The flask geometry includes a perimeter ridge to ensure stable stacking in the incubator, maximizing shelf space while allowing for uniform thermal distribution.

• Secure Tracking: Features clear, molded graduations for easy volume estimation and a frosted writing area for secure sample identification and labeling.
