Which component of a syringe can also be referred to as a stopper or seal?

In a syringe, the plunger tip is the component that functions as a stopper or seal. This is crucial for maintaining the integrity and functionality of the syringe. The plunger is the part that is pushed to expel the liquid from the barrel, and its tip fits snugly against the inner walls of the barrel. This secure fit creates an airtight seal, preventing the liquid from leaking out when the plunger is in place.

The design of the plunger tip is intended to optimize the control of fluid delivery and to prevent contamination of the medication within the barrel. When the plunger is drawn back, it creates a vacuum that allows the syringe to draw up fluid, which is essential for accurate dosing in compounding practices.

Understanding the role of the plunger tip is vital in sterile compounding, as ensuring that all components function effectively is key to maintaining sterility and accuracy in medication preparation.
