SYRINGE

YOUR LIFE

A syringe is a simple reciprocating pump consisting of a plunger (actually a piston) that fits tightly within a cylindrical tube (called a barrel). The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle, or a tubing to help direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous drugs into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids.

HOW TO USE

1. Decide what length and gauge needle you will need, and locate one.

2. Make sure pressure can be released from the vessel you plan to syringe liquid into.

3.Pull the liquid into the syringe, taking slightly MORE than you need for your experiment.
