Description
Product Overview
The Celltreat 229351 Tissue Culture Treated Flask is engineered for researchers who demand consistency, sterility, and ease of use in cell culture applications. Constructed from high‑quality borosilicate glass, the flask provides excellent chemical resistance and thermal stability, allowing it to withstand repeated autoclave cycles without compromising structural integrity. The interior surface is treated to create a uniform hydrophilic coating, which encourages even cell attachment and spreading, reducing variability between experiments. Each flask holds 600 mL of culture medium and offers a growth area of 182 cm², making it suitable for a wide range of cell lines, including adherent and suspension cultures. The vent cap incorporates a 0.22 µm hydrophobic membrane that permits gas exchange while preventing microbial contamination, ensuring optimal oxygen and carbon dioxide balance for healthy cell growth. All flasks are gamma‑irradiated and sealed in zip‑closure bags to guarantee a sterile environment from the moment they are opened.

Usage
Designed for versatility, the Celltreat flask fits seamlessly into standard laboratory workflows. Its canted neck design provides easy access for pipetting, media changes, and cell harvesting, reducing the risk of spills and improving ergonomics during prolonged handling. The flask is compatible with most incubators, shakers, and orbital platforms, allowing researchers to perform static cultures, gentle agitation, or dynamic perfusion as required by their protocols. Whether you are conducting routine passaging, high‑throughput screening, or specialized differentiation studies, the flask’s robust construction and reliable venting system support consistent environmental conditions. The sterile packaging eliminates the need for additional decontamination steps, saving valuable time and reducing the chance of introducing contaminants. Moreover, the clear glass body enables visual monitoring of cell confluence and morphology without removing the flask from the incubator, preserving culture integrity.

FAQ
What types of cells are suitable for this flask?
The flask is ideal for both adherent and suspension cell lines, including mammalian, insect, and stem cells, thanks to its hydrophilic surface and ample growth area.
Can the flask be autoclaved after opening?
Yes, the borosilicate glass construction tolerates standard autoclave cycles (121 °C, 15 psi) without compromising the integrity of the vent cap membrane.
How does the vent cap prevent contamination?
The vent cap incorporates a 0.22 µm hydrophobic membrane that blocks microorganisms while allowing diffusion of gases, maintaining a sterile environment during incubation.
Is the flask compatible with high‑throughput screening equipment?
Absolutely. Its standard dimensions fit most robotic handling systems, plate readers, and automated incubators, facilitating integration into high‑throughput workflows.
What is the recommended storage condition for unopened flasks?
Store unopened flasks in a cool, dry place away from direct sunlight. The sterile zip‑closure bags protect the flasks from moisture and contaminants until use.
