What is a syringe used for in chemistry?

Syringes are usedteaching labsas well as some research labs. The primary use of syringes is delivering liquid reagents to the reaction mixture under inert atmosphere. The reaction vessel is closed with a septum and pressurized, perhaps with nitrogen.

Since the reagents cannot simply be poured, syringes are used to deliver the reagents to the vessel, without compromising the seal on the septum. It is also more convenient to measure small volumes with a syringe than with a graduated cylinder, and thus syringes may also be used for measuring volumes of liquid reagents.
