Corning Cell Culture Flask Types
Flask Type | Growth Area / Format | Best For | Key Benefits |
| Single‑layer, multiple growth area sizes | Routine adherent cell culture and maintenance | Reliable, general‑purpose surface; familiar handling and workflow; supports consistent cell attachment and growth. | |
| Single‑layer, non‑treated surface | Suspension cultures or applications where cell attachment is not desired | Inert surface minimizes cell attachment; ideal for suspension cells or specialized protocols. | |
Enhanced Attachment T‑flasks (e.g., Corning CellBIND® surface) | Single‑layer, treated surface | Cells with higher attachment requirements or serum‑reduced conditions | Promotes stronger cell attachment and spreading; supports consistent growth of more challenging cell lines. |
| Single‑layer flask with U‑shaped shoulders and canted neck | Labs wanting easier handling and smoother harvesting, with the same culture performance | Rounded shoulders for easier grip and cap access; fewer corners for improved cell scraping; supports use of a larger pipet (up to 50 mL); reduced plastic vs. standard T-75 and T-150 flask designs (e.g., 23% less for T-75; 30% less for T-150). | |
High‑density/Scale‑up Vessels (e.g. Corning HYPERFlask vessel) | Large growth area formats (for expansion/process development) | High‑yield cell expansion and process development | Designed to increase output while saving space and improving efficiency during expansion. |

Surface Type | Recommended Use | Why Choose It |
Non-treated | Suspension cells or non‑adherent applications | Prevents unwanted cell attachment. |
TC‑treated | Most standard adherent cell lines | Reliable surface for routine attachment and growth. |
Ultra-Low Attachment (ULA) | Spheroid formation, tumorsphere assays, stem cell aggregates, and other 3D/suspension applications | Minimizes cell adhesion to the flask, encouraging cells to aggregate with each other instead of attaching to plastic. |
Corning CellBIND | Primary cells, difficult-to-attach cells, or cultures in low-serum/reduced-serum conditions | Enhanced surface chemistry improves cell attachment and consistency without needing a biological coating. |
Collagen-coated | Attachment-sensitive cells such as many primary, epithelial, or neuronal cells | Biological coating supports adhesion and can improve growth and morphology for demanding cell types. |
About Corning U-shaped Flasks
- Plug seal caps feature one-piece linerless construction and are designed for use in closed systems, providing a liquid- and gas-tight seal. When loosened, this cap can also be used in open systems. This cap design was a Corning innovation that first appeared in 1974.
- Phenolic-style caps are designed (when loosened) for use in open systems requiring gas exchange. With the caps slightly loosened, gas is exchanged between the environments inside and outside of the flask.
- Vent caps contain a 0.2 µm pore, hydrophobic membrane sealed to the cap, isolating the container it is placed on from the environment while providing consistent gas exchange. These caps are highly recommended for use in all CO2 incubators, especially for long-term use. The vent cap was a Corning innovation that first appeared in 1988.

Sustainable Cell Culture Flask Solutions
Sustainable Cell Culture Flask Solutions
Select cell culture flask formats use less plastic compared to traditional formats, helping labs reduce material usage. The Corning U-shaped 75 cm2 flask uses 23% less plastic than the standard T-75 flasks, and U-shaped 150 cm2 flask uses 30% less plastic than the standard T-150 flasks –all while keeping the same cell culture surface area. The Corning HYPERFlask vessel uses 50% less plastic compared to using 10 equivalent T-175 flasks. Supply your lab sustainably with Corning cell culture vessels.
How to Create an Ideal Environment for Growing Cells
Frequently Asked Questions
-
What sizes are available, and how do I choose the right growth area?
Corning offers a variety of culture flask sizes ranging from T-25, T-75, T-150, T-175, and T-225. As a rule of thumb, select a growth area that supports your target seeding density and harvest yield while fitting your incubator space and preferred working volumes—smaller formats are useful for routine maintenance and early experiments, while larger formats help reduce handling steps during expansion workflows.
Available non-treated, TC-treated, with Ultra-Low Attachment surface, or Corning CellBIND surface.
-
How do I choose between non-treated, TC-treated, and enhanced-attachment surfaces?
Choose the surface based on whether you want cells to attach and how demanding your culture conditions are.
Non-treated surfaces are intended for suspension cells or workflows where attachment is not desired.
TC-treated surfaces are a general-purpose option for most standard adherent cell lines.
Enhanced-attachment surfaces (such as Corning CellBIND) are designed to promote stronger, more consistent attachment and growth for more challenging cell types and can be helpful in serum-reduced or otherwise demanding conditions.
-
How does the Corning U-shaped flask design improve handling and cell harvesting?
Corning’s U-shaped flasks feature a canted neck and rounded shoulders designed to improve grip and cap access. The reduced number of corners can support smoother cell scraping and harvesting, and the ergonomic shape can make routine handling steps more efficient. The design also supports the use of a larger pipet (up to 50 mL), which can help when adding or removing larger working volumes.
-
When should I choose a high-density/scale-up vessel (e.g., Corning HYPERFlask vessel) instead of multiple standard flasks?
Consider a scale-up vessel when you need higher yield with fewer handling steps. For example, the Corning HYPERFlask vessels provide approximately 10X the growth area of a 175 cm2 flask in a similar footprint and use a gas-permeable film to support efficient gas exchange. This can help streamline expansion and support workflows where efficiency, space savings, and potential automation compatibility are priorities.
-
When do I need an Erlenmeyer flask instead of a T-flask?
Use T‑flasks for adherent cultures and other static workflows where cells grow on a treated surface in a standard incubator. Choose an Erlenmeyer flask when your protocol calls for suspension growth with agitation, such as cultures that need continuous mixing to keep cells in suspension, improve mass transfer, or support higher oxygen transfer in a shaker incubator.
If you’re feeding and harvesting from a flat growth surface, a T‑flask is typically the right choice; if you’re optimizing shaking speed, working volume, and aeration for a suspension process, an Erlenmeyer flask is usually the better fit.
