Vials & Syringes

Vials:
A small bottle that contains a drug (especially a sealed sterile container for injection by needle)
A glass or plastic vessel used for storing drinks or other liquids; typically cylindrical without handles and with a narrow neck that can be plugged or capped.
Plastic vials can have other closure systems, such as flip-tops or snap caps. A vial can be tubular, or have a bottle-like shape with a neck.

Syringes:
A syringe is a simple pump consisting of a plunger that fits tightly in a tube. The plunger can be pulled and pushed along inside a cylindrical tube (called a barrel), allowing the syringe to take in and expel a liquid or gas through an orifice at the open end of the tube.

The open end of the syringe may be fitted with a hypodermic needle, a nozzle, or tubing to help direct the flow into and out of the barrel. Syringes are often used to administer injections, insert intravenous drugs into the bloodstream, apply compounds such as gluer lubricant, and measure liquids.
