Celltreat 229330 Tissue Culture Treated Flask 250mL Plug Cap

Description

Product Overview

The Celltreat 229330 Tissue Culture Treated Flask is engineered to meet the rigorous demands of modern cell biology laboratories. Constructed from high‑quality borosilicate glass, the flask offers exceptional chemical resistance and thermal stability, ensuring that it can withstand repeated sterilization cycles without compromising structural integrity. Its uniform hydrophilic surface is specifically treated to promote consistent cell attachment, reducing variability and enhancing the reliability of experimental results. With a 250mL working volume and a canted neck design, the flask provides ample space for cell growth while allowing convenient access for media changes, sampling, and manipulation. The plug seal cap, made from autoclavable polypropylene, creates a secure, leak‑proof closure that maintains sterility throughout the culture period. Each flask is gamma‑irradiated and sealed in a zip‑closure bag, guaranteeing a sterile environment straight from the package. Detailed specifications include a package dimension of 21 × 13.3 × 10.2 inches, a weight of 11.71 lb, and compliance with industry standards for cell culture equipment.

Usage

This flask is ideal for a wide range of cell culture applications, from routine maintenance of adherent cell lines to more specialized protocols such as transfection, differentiation, and drug screening. Researchers working in academic, biotech, and pharmaceutical settings will appreciate the ease of handling provided by the canted neck, which minimizes the risk of spillage and allows for precise pipetting. The sterile packaging eliminates the need for additional decontamination steps, saving valuable time and reducing the potential for contamination. The flask’s design supports both static and dynamic culture methods, making it compatible with incubators, shakers, and bioreactors. Whether you are cultivating mammalian, insect, or plant cells, the treated surface ensures that cells adhere uniformly, facilitating downstream analyses such as microscopy, flow cytometry, and biochemical assays.

FAQ

What types of cells can be cultured in this flask?

The flask is suitable for a broad spectrum of adherent cell types, including mammalian cell lines (e.g., HEK293, CHO, NIH‑3T3), primary cells, insect cells, and certain plant cell cultures. The treated surface promotes uniform attachment, making it adaptable to most standard cell culture protocols.

Is the flask compatible with autoclave sterilization?

Yes. The borosilicate glass construction and polypropylene plug cap are both autoclavable. The flask can be sterilized at 121 °C for 15 minutes without degradation of the surface treatment or the integrity of the glass.

Can the flask be used for suspension cultures?

While the flask is optimized for adherent cultures, it can accommodate suspension cultures up to the 250 mL volume. However, for large‑scale suspension work, dedicated spinner flasks or bioreactors may provide better mixing efficiency.

How does the gamma irradiation affect the flask’s performance?

Gamma irradiation is performed at a dose that ensures sterility while preserving the hydrophilic surface treatment. Independent testing has shown that the treated surface retains its cell‑attachment properties after irradiation, so there is no negative impact on performance.

What support does Celltreat provide if I encounter an issue?

Celltreat offers a dedicated technical support team reachable via email or phone. Customers can receive assistance with product selection, troubleshooting, and protocol optimization. Additionally, the company provides a warranty that covers manufacturing defects, reinforcing confidence in product quality.
