Cell culture molecular biology primarily involves cultures of cells on flat plastic dishes. This technique is known as two-dimensional (2D) cell culture, and was first developed by Wilhelm Roux who, in 1885, removed a portion of the medullary plate of an embryonic chicken and maintained it in warm saline for several days on a flat glass plate. From the advance of polymer technology arose today's standard plastic dish for 2D cell culture, commonly known as the Petri dish. Julius Richard Petri, a German bacteriologist, is generally credited with this invention while working as an assistant to Robert Koch. Various researchers today also
Kidney dish Kidney dish A kidney dish (British English) or emesis basin (American English) is a shallow basin with a kidney-shaped base and sloping walls (hence its alternate name) used in medical and surgical wards to receive soiled dressings and other medical waste.
