Polystyrene Cell Culture Flasks 4E’s 60pcs Sterile 25cm² Vent Cap

Description

Product Overview

The 4E’s USA Polystyrene Cell Culture Flasks are engineered to meet the demanding requirements of modern cell biology laboratories. Constructed from high‑quality, clear polystyrene, each flask provides excellent optical clarity for microscopic observation while maintaining a robust barrier against contamination. The 25 cm² culture area is optimized for adherent cell lines, delivering a uniform surface that promotes consistent attachment and growth. A short, broad, angled neck design facilitates easy access for inoculating loops, cell scrapers, and pipettes, reducing the risk of spills and improving workflow efficiency. The vented cap incorporates a sterile filter that allows gas exchange while preventing microbial ingress, ensuring a stable environment for cell cultures over extended incubation periods.

Usage

These flasks are suitable for a broad spectrum of applications, ranging from routine cell line maintenance to high‑throughput screening and large‑scale biomanufacturing. Researchers working with mammalian, insect, or plant cells will appreciate the non‑pyrogenic, DNase/RNase‑free surface, which minimizes background interference in downstream assays such as ELISA, PCR, and western blotting. The gamma‑irradiated sterilization process guarantees a sterile product without the need for additional autoclaving, saving valuable time and resources. In educational settings, the clear vessel and ergonomic design make it easy for students to visualize cell morphology and understand fundamental concepts of cell culture, making these flasks an ideal teaching tool for undergraduate and graduate courses.

FAQ

What cell types are compatible with these flasks?

The flasks are suitable for a wide range of adherent and suspension cell lines, including mammalian, insect, and plant cells. Their non‑pyrogenic surface makes them ideal for sensitive assays.

Can the flasks be autoclaved after receipt?

Yes, although they are pre‑sterilized by gamma irradiation, they can safely withstand standard autoclave cycles if additional sterilization is required.

How should the flasks be stored before use?

Store the flasks in a clean, dry environment at room temperature. Keep the packaging sealed until the point of use to maintain sterility.

What is the recommended incubation temperature?

These flasks are designed for typical cell culture conditions, generally 37 °C for mammalian cells, with appropriate CO₂ levels as dictated by the specific cell line.

Is technical assistance available for troubleshooting?

Absolutely. Our technical support team is available to help with protocol optimization, equipment compatibility, and any other questions you may have regarding the use of our flasks.
