Description
Product Overview
The Ucallm cell culture flask is engineered from optically clear polystyrene that delivers over 90% light transmittance, allowing researchers to monitor cell morphology without removing the vessel from the incubator. Each flask is available in four surface treatments—TC treated and non‑TC treated—providing flexibility for adherent or suspension cell lines. The 75 cm² format offers a generous growth area while maintaining a compact footprint, making it ideal for high‑throughput applications in both academic and industrial laboratories.
Designed with a wide‑mouth bottleneck, the flask facilitates effortless media exchange, cell harvesting, and the insertion of sterile accessories such as filters or sampling syringes. The vent cap incorporates a 0.22 µm breathable membrane that permits efficient gas exchange while protecting cultures from airborne contaminants. All flasks are supplied sterile, sealed in double‑layer packaging to preserve aseptic conditions until the moment of use.
Dimensions and weight are optimized for stability on standard laboratory benches and incubators. The package dimensions of 17.13 × 16.34 × 14.57 inches and a net weight of 16.09 lb per case ensure easy handling and storage. Manufactured by Ucallm, a trusted name in laboratory consumables, each flask meets rigorous quality standards and is backed by a comprehensive warranty.
Usage
Ucallm cell culture flasks are suitable for a broad spectrum of cell culture techniques, including routine maintenance of adherent cell lines, 3‑D spheroid formation, and high‑density suspension cultures. The vent cap’s breathable membrane supports optimal oxygen and carbon dioxide diffusion, which is critical for maintaining pH balance and cell viability during prolonged incubations.
Researchers working in stem cell labs, vaccine development, and biopharmaceutical production can rely on the TC‑treated surface to promote rapid cell attachment and uniform spreading. Non‑TC treated variants are perfect for applications where minimal surface interaction is required, such as certain primary cell cultures or delicate suspension lines. The clear scale markings on both sides of the flask enable precise volume assessments, reducing the risk of over‑ or under‑filling.
Because the flasks are compatible with standard laboratory equipment—including orbital shakers, centrifuges, and automated liquid handling systems—they integrate seamlessly into existing workflows. The robust cap thread prevents accidental loosening, ensuring a secure seal during transport between biosafety cabinets and incubators.
Why Choose Us
Ucallm’s commitment to quality begins with raw material selection. The polystyrene used in each flask is sourced from certified suppliers and undergoes a stringent extrusion process that eliminates impurities and guarantees consistent optical clarity. Each batch is tested for light transmission, surface uniformity, and sterility before release.
Our manufacturing facilities adhere to ISO 13485 and GMP guidelines, providing an additional layer of assurance for critical research applications. The flasks are individually sealed in a sterile barrier system that protects against microbial ingress, allowing users to open the product directly in a laminar flow hood without additional decontamination steps.
Beyond product excellence, Ucallm offers responsive technical support and a dedicated customer service team. Whether you need assistance selecting the appropriate surface treatment, troubleshooting cap issues, or obtaining documentation for regulatory submissions, our experts are available to help you achieve reliable experimental outcomes.

FAQ
What is the difference between TC‑treated and non‑TC‑treated flasks?
TC‑treated flasks have a surface coating that enhances cell adhesion, making them ideal for adherent cell lines that require a strong attachment substrate. Non‑TC‑treated flasks have an untreated surface, which is useful for suspension cultures or primary cells that need minimal interaction with the vessel.
Can the vent cap be used with standard incubators?
Yes. The vent cap’s 0.22 µm breathable membrane is designed to fit standard CO₂ incubators. It allows sufficient gas exchange while maintaining a sterile barrier, so you can keep cultures in a controlled environment without risking contamination.
How should the flasks be stored before use?
Store the flasks in a clean, dry area at room temperature. Keep the original packaging intact until you are ready to open the flask in a sterile environment. Avoid exposure to direct sunlight or extreme temperature fluctuations, which could affect the integrity of the sterile seal.
Are the flasks compatible with automated liquid handling systems?
Absolutely. The flasks are designed to fit standard robotic grippers and pipetting heads. The wide mouth and clear scale markings facilitate precise volume measurements, and the robust cap thread prevents accidental loosening during automated operations.
What warranty does Ucallm provide for these flasks?
Ucallm offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues related to material quality or sterility, contact our customer support team with the batch number and purchase details for a replacement or refund.
