CELLTREAT 229371 225cm2 Tissue Culture Flask with Vent Cap Pack of 25

Description

Product Overview

The CELLTREAT 229371 225cm2 Tissue Culture Flask is engineered for demanding cell culture applications where sterility, gas exchange, and ease of handling are paramount. Constructed from high‑quality borosilicate glass, the flask offers excellent chemical resistance and thermal stability, allowing it to withstand autoclaving, UV sterilization, and a wide temperature range without compromising structural integrity. The vented cap incorporates a precision‑engineered filter that permits free diffusion of oxygen and carbon dioxide while maintaining a robust sterile barrier, eliminating the need for additional gas‑exchange devices.

Measuring 225cm2 of growth surface, the flask provides ample area for adherent cell lines, primary cultures, and suspension cultures. The canted neck design, combined with a large opening, facilitates effortless access for cell scrapers, pipettes, and media exchange, reducing the risk of contamination and minimizing cell loss during routine procedures. The stable, wide‑base geometry ensures that the flask can be filled and incubated upright, preventing spillage and enabling consistent positioning within standard incubators and shakers.

Each unit is supplied in a zip‑closure bag that protects the flask from dust and mechanical damage during storage and transport. The case contains 25 flasks, offering laboratories a cost‑effective solution for high‑throughput experiments, batch processing, and reproducible research workflows. Detailed product specifications, including dimensions, weight, and model number, are provided to assist with inventory management and compatibility checks.

Usage

Designed for versatility, the CELLTREAT 229371 flask excels in a variety of laboratory settings, from academic research labs to industrial bioprocessing facilities. Its vented cap is ideal for cultures that require precise control of atmospheric gases, such as stem cell maintenance, viral production, and metabolic studies. The flask’s robust glass construction tolerates repeated media changes, sub‑culturing, and centrifugation steps, making it suitable for long‑term culture and high‑density cell growth.

When used in conjunction with standard laboratory equipment—such as orbital shakers, incubators, and laminar flow hoods—the flask integrates seamlessly into existing workflows. The large opening allows for rapid addition of reagents, while the canted neck reduces the likelihood of accidental spills during pipetting. Researchers can employ the flask for both adherent and suspension cell lines, benefiting from the uniform temperature distribution and efficient gas exchange provided by the vented cap.

For quality‑controlled environments, the zip‑closure bag ensures that each flask remains sterile until the moment of use, simplifying aseptic technique and reducing preparation time. The case of 25 flasks supports batch processing, enabling simultaneous setup of multiple experiments with consistent conditions across replicates.
