VWR® Disposable Petri Dish

100% sterility guaranteed. These plastic Ultra-Dish petri dishes are packed in a double-sealed polyethylene sleeve to keep dishes sterile during transit, storage, and handling. These heavy, clear dishes have consistently flat bottoms (never more than 0.005" off flat from edge to center). Flat dishes require less media for adequate coverage in the center of the dish. Designed for easy one-handed opening and closing. Edges are squared off to provide a firm, sure grip. This dish works well with FOSS units. Certificate of sterility is available upon request.
