Culture plates are essential laboratory consumables used in microbiology, cell biology, and biomedical research. These sterile, flat dishes with lids provide a controlled environment for culturing microorganisms, cells, or tissues. Available in various materials (e.g., polystyrene, glass) and surface treatments (e.g., treated for adhesion), they come in standard sizes like 35mm, 60mm, or 100mm diameters. Common types include Petri dishes, multi-well plates (6-well, 12-well, 24-well, 96-well), and specialized plates for specific applications (e.g., deep-well plates for suspension cultures). Key features may include optical clarity for microscopy, stackability, and gamma irradiation for sterilization. Typical products in this category include disposable Petri dishes, cell culture plates, bacterial culture plates, and assay plates for high-throughput screening.
