The containers are made of medical-grade plastic materials (polypropylene and polystyrene) for the collection and transportation of urine and faecal samples. Sample collection containers have integrity seals and LIDS that allow them to easily identify samples and ensure their safety. The seal provides a place to write the room number, name and doctor. The ridged lid makes handling easy, even with gloves on. Screw cap allows safe closing. Each sterile container has a ridged scale for easy monitoring of liquid levels.
