Corning Culture Flask 150 cm2 Polystyrene Canted Neck with Vent Cap Case of 50 Flasks

Corning 431465 150 cm2 Polystyrene Canted Neck Culture Flasks (Case of 50)

Engineered to maximize cellular expansion and streamline aseptic handling, the Corning 431465 150 cm2 culture flask is a premium vessel for large-scale adherent cell culture. Manufactured from highly purified, optically clear virgin polystyrene, this flask delivers distortion-free visibility for routine phase-contrast microscopy and morphological assessments. The internal growth surface undergoes a specialized vacuum-gas plasma tissue culture (TC) treatment, promoting a uniformly hydrophilic environment that ensures superior attachment, spreading, and proliferation of anchorage-dependent mammalian cell lines. The ergonomic canted neck design significantly improves the accessibility of serological pipettes and cell scrapers to the entire growth surface, while concurrently reducing the risk of airborne contamination during media exchanges. Fully sterilized, non-pyrogenic, and tested for structural integrity to prevent leaks, this bulk case of 50 flasks provides the strict reliability required for high-throughput virology, oncology, and stem cell research laboratories.

Technical Performance and Design

• Ergonomic Canted Neck: Angled precisely to allow unhindered reach for pipettes and cell scrapers into all corners of the flask, while minimizing the exposure of the open neck to descending airborne particulates in the biosafety cabinet.

• Vacuum-Gas Plasma TC Treatment: Permanently alters the hydrophobic polystyrene surface to become hydrophilic, creating an optimal electrostatic profile for robust cellular adhesion and uniform monolayer formation.

• Optical-Grade Polystyrene Construction: Delivers glass-like transparency paired with shatter-resistant durability, ensuring researchers can perform high-resolution daily confluence checks without optical interference.

• Molded Volumetric Graduations: Features crisp, easily readable volumetric scales molded directly into the plastic, offering rapid visual confirmation of media volumes during fast-paced feeding schedules.
