Description_x000D_ General description_x000D_ Innovative features and outstanding cell growth properties make the TPP tissue culture dishes the ideal choice for adherent cell culture in research and industry. These optically clear, high-grade polystyrene tissue culture dishes are tissue culture treated only on the base of the dish with a non-treated ring surrounding the growing surface to prevent cell attachment on the edge. A serrated ring around the bottom culture dish makes pick-up and handling of the dishes safe and easy, while also minimizing the risk of dropping dishes due to lid/base disassembly._x000D_ A special stacking ring, with spaces for a numeric scale (12, 3, 6, 9) set on the periphery, allows for safe and stable stacking of these tissue culture dishes. The numeric scale serves to ease locating areas of examination while the spaces they create in the stacking ring reduce condensation between stacked dishes and prevent the tissue culture dishes from sticking together._x000D_ Two marking areas, located on the top dish wall (yellow) and the bottom dish wall (frosted), act as a reference for top/bottom alignment and orientation. There are also six special stops built into the lid which facilitate optimal gas exchange during incubation._x000D_ Features:_x000D_ • Every batch tested for cell growth characteristics_x000D_ • Outstanding flatness and optical clarity for microscopic examination_x000D_ • Unique serrated edge on bottom dish makes handling safe and easy_x000D_ • Double writing surface_x000D_ • Numeric scale in lid divides viewing area into quadrants to aid in examination_x000D_ • Dishes are packaged in easy "peel-off" wrapping_x000D_ • Guaranteed sterile by gamma irradiation_x000D_ Legal Information_x000D_ TPP is a registered trademark of TPP Techno Plastic Products AG
