A sample container for stool and urine is a specialized, sterile vessel designed for the collection, storage, and transportation of biological samples. For stool samples, the container is usually a small, leak-proof polystyrene jar with a secure lid and may come with a scoop for easy collection. For urine samples, the container is typically a clear, plastic cup with a screw-on or snap-on lid, often featuring graduated markings for volume measurement.
