Medical-grade disposable hypodermic syringes are often used in research laboratories for convenience and low cost. They are often used for measuring and transferring solvents and reagents where a high precision is not required.
Used with a needle or cannula, syringes are also useful for transferring fluids through rubber septa when atmospheric oxygen or moisture are being excluded. Examples include the transfer of air-sensitive or pyrophoric reagents.
