diperbuat daripada bahan polistirena gred perubatan dengan ketelusan yang tinggi. Mengikut proses rawatan permukaan yang berbeza, ia dibahagikan kepada dua jenis: hidrofilik dan hidrofobik.: digunakan untuk penanaman sel yang melekat. Pertumbuhan sel tersebut mesti mempunyai permukaan sokongan yang boleh dilekatkan, dan sel boleh membesar dan membiak pada permukaan ini dengan bergantung pada faktor lampiran yang dirembeskan oleh mereka sendiri atau disediakan dalam medium kultur. Permukaan botol telah menjalani rawatan pengubahsuaian khas untuk memperkenalkan kumpulan hidrofilik. Tujuannya adalah untuk meningkatkan prestasi lekatan permukaan botol, yang lebih sesuai untuk pertumbuhan sel.kelalang kultur sel
Di atas ialah dua jenis kelalang kultur sel, yang terutamanya sesuai untuk skala sederhana kultur sel dan tisu di makmal. Reka bentuk kesesakan yang luas memudahkan pipet dan pengikis sel untuk menghubungi permukaan pertumbuhan.Kelalang kultur sel hidrofobik
The above are two types of cell culture flasks, which are mainly suitable for medium-scale cell and tissue culture in the laboratory. The wide bottleneck design facilitates the pipette and cell scraper to contact the growth surface.
