In microbiology, a cell spreader or plate spreader is a tool used to smoothly spread cells and bacteria on a culture plate, such as a petri dish.
Cell spreaders can be made from glass, plastic, or metal, and come in various shapes.
A Drigalski spatula is a cell spreader consisting of a cylindrical rod or wire bent in the shape of a triangle with a handle.[1][2][3] Another variant is a rod bent in L-shape.[4] Extrusion molded versions can be T-shaped.[5]
