The barrel is a crucial component of a syringe, serving as the main body that holds the fluid to be injected or withdrawn. Here’s an in-depth look at the barrel part of a syringe: Description and Function Structure Cylindrical Shape: The barrel is typically cylindrical, allowing for smooth movement of the plunger inside. Transparent Material: Often made from transparent plastic (such as polypropylene) or glass, enabling clear visibility of the fluid level and any air bubbles. Graduations Measurement Marks: The barrel is marked with graduations (measurement lines) that indicate the volume of fluid contained within. These marks are essential for accurate dosing. Units: Graduations can be in milliliters (ml), cubic centimeters (cc), or units specific to certain medications like insulin. 3 .
