Syringe model specification

Generally, 2 ml, 5 ml, 10 ml or 20 ml syringes are used, occasionally 50 ml or 100 ml syringes are used, and 1 ml syringes are used for intradermal injections.
Syringes can be made of plastic or glass, and usually have a scale indicating the volume of liquid in the syringe. Glass syringes can be sterilized with an autoclave, but because plastic syringes are cheaper to dispose of, most modern medical syringes are made of plastic, further reducing the risk of blood-borne diseases. The re-use of needles and syringes is associated with the spread of diseases, especially HIV and hepatitis, among intravenous drug users.
