• High-transparency Polystyrene Material​: our cell culture flasks crafted from thickened polystyrene, the flask features high transparency, facilitating clear microscopic observation of cell growth; Tissue culture bottle robust structure resists deformation, maintaining stability during handling and incubation; Dimensions are 6 x 3.1 x 1.5 inches/15.2 x 8 x 3.7cm, providing ample space for cell expansion while fitting standard laboratory equipment
• Secure Sealing and Convenient Labeling​: the tissue culture kit equipped with a frosted writing area, the flask allows easy marking of sample information; Dual-sided volume graduation lines enable real-time monitoring of culture medium levels, aiding in precise experimental control; The sealing design prevents leakage and minimizes the release of metal ions, ensuring the integrity of cell cultures
• Sterile Tc-treated Surface​: subjected to gamma irradiation sterilization and tissue culture (TC) treatment, the flask's surface is optimized for cell adhesion and growth; It supports various cell types, including those with high sensitivity, making it suitable for cell culture and expansion experiments in laboratories and educational institutions
• Efficient Gas Exchange​: the vented filter cap design maintains gas balance in open culture environments, supporting normal cellular metabolism; Combined with advanced TC treatment, it enhances cell attachment efficiency, promoting consistent growth conditions and reliable experimental outcomes
• User-friendly Operation Design​: the wide, short neck structure is compatible with pipettes, cell scrapers, and other common tools, simplifying liquid transfer and cell harvesting; The angled neck design reduces operational complexity, streamlining workflows and improving overall experimental efficiency
