This new line of cell culture dishes supports a range of applications and growth of many cell types including primary, stem, neuronal, mesenchymal, hepatocyte, and endothelial cells. Available in a range of sizes and styles, these cell culture dishes are designed for performance and ease-of-use. They include lids designed to promote optimal gas exchange and rings that facilitate stacking and handling. Combining high-pressure molded 100% USP VI Class virgin crystal polystyrene with a low-pressure gas plasma surface treatment, the dishes enable cells to adhere more efficiently to the surface by reducing its hydrophobicity.
