Standard TC-Treated Cell Culture Flasks
Corning® TC-treated flasks are designed for routine adherent mammalian cell culture applications. Vacuum gas plasma surface treatment promotes reliable cell attachment, spreading and growth across a broad range of cell lines.
| Product Code | Growth Area | Flask Style | Description |
|---|---|---|---|
| 430639 | 25 cm² | Canted Neck, Vent Cap | TC-treated rectangular flask for routine adherent cell culture applications. |
| 430168 | 25 cm² | Canted Neck, Plug Seal Cap | Plug seal TC-treated flask for reduced gas exchange workflows. |
| 430641U | 75 cm² | U-Shaped, Vent Cap | Ergonomic U-shaped TC-treated flask with improved pipette and scraper access. |
| 431080 | 175 cm² | U-Shaped, Angled Neck, Vent Cap | Large-area TC-treated flask designed for scale-up adherent culture. |
| 431081 | 225 cm² | Angled Neck, Plug Seal Cap | 225 cm² TC-treated flask with plug seal cap for controlled gas exchange. |
| 431082 | 225 cm² | Angled Neck, Vent Cap | 225 cm² TC-treated flask with vented cap for long-term incubator workflows. |
CellBIND® Surface Flasks
CellBIND® surface flasks feature Corning’s proprietary surface modification technology, creating a more hydrophilic growth surface that improves attachment consistency, cell growth and yields — particularly for sensitive or difficult-to-culture cell lines.
| Product Code | Growth Area | Flask Style | Description |
|---|---|---|---|
| 3289 | 25 cm² | Canted Neck, Vent Cap | CellBIND® flask for enhanced attachment of sensitive adherent cells. |
| 3290 | 75 cm² | U-Shaped, Vent Cap | Ergonomic CellBIND® flask with enhanced cell attachment surface. |
| 3292 | 175 cm² | Angled Neck, Vent Cap | Large-area CellBIND® flask for scale-up mammalian cell culture. |
| 3293 | 225 cm² | Angled Neck, Vent Cap | 225 cm² CellBIND® flask for improved growth consistency and yields. |
Ultra-Low Attachment Flasks
Corning® Ultra-Low Attachment flasks are designed to minimise cell attachment, making them ideal for suspension cultures, spheroid formation, stem cell applications and serum-free workflows. The covalently bonded hydrogel surface helps prevent protein adsorption and anchorage-dependent cell attachment.
| Product Code | Growth Area | Flask Style | Description |
|---|---|---|---|
| 3815 | 25 cm² | Rectangular, Canted Neck, Vent Cap | Ultra-Low Attachment flask for suspension culture and spheroid applications. |
| 3814 | 75 cm² | U-Shaped, Canted Neck, Vent Cap | Ergonomic Ultra-Low Attachment flask with improved scraping and pipette access. |
| 3816 | 175 cm² | U-Shaped, Angled Neck, Vent Cap | Large-area Ultra-Low Attachment flask designed for stem cell and tumor spheroid workflows. |
Untreated Suspension Culture Flasks
Corning® untreated suspension culture flasks are designed for applications where cell attachment is not desired, including suspension culture, hybridoma workflows, protein expression, and shaker culture applications. Manufactured from optically clear virgin polystyrene, these flasks provide excellent visibility and sterility assurance for routine laboratory workflows.
| Product Code | Growth Area | Flask Style | Description |
|---|---|---|---|
| 430720 | 25 cm² | Canted Neck, Vent Cap | Untreated suspension culture flask designed for non-adherent cell culture applications. |
| 430721 | 75 cm² | U-Shaped, Vent Cap | Ergonomic untreated flask for suspension culture and shaker workflows. |
| 430722 | 175 cm² | Angled Neck, Vent Cap | Large-area untreated flask suitable for suspension and hybridoma culture. |
| 430725 | 225 cm² | Angled Neck, Vent Cap | 225 cm² untreated suspension flask for scale-up and high-volume culture applications. |
