Syringes are used for many tasks. Hypodermic syringes are used for medical injections but there are other types of syringes. Other types of medical syringes include syringes for flushing wounds, for dosing, and for feeding. Many syringes can be glass or disposable plastic but the most precise syringes are glass. Most syringes have standard luer slip or luer lock tip to which a needle is attached; some have a permanently attached needle.. Disposable medical syringes have a plastic barrel and plunger with a rubber piston. Reusable medical syringes have glass barrels and pistons; the barrels and pistons are carefully matched for a precise fit. Medical syringes range in size from 0.3ml to 250 ml
For precise liquid handling in the laboratory glass syringes are used with either a metal or PTFE plunger. These types of syringes range in volume from 0.5ul to 500ml. Syringes for liquid handling can have a luer slip tip, a luer lock tip, a knurled hub, or the needle may be cemented onto the syringe. Gas tight syringes are used for more volatile liquids and very precise volume requirements. Liquid handling syringes are used in autosamplers for automated LC, GC, HPLC, and other lab instruments.
