定义
The syringe barrel is the primary cylindrical body of a syringe assembly, designed to hold and accurately dispense liquids or gases. It features a precisely engineered inner diameter for smooth plunger movement, calibrated volume markings for measurement accuracy, and a luer lock or slip tip connection for secure attachment of needles or tubing. This component ensures controlled fluid transfer in medical, pharmaceutical, laboratory, and industrial applications.
工作原理
The syringe barrel operates on the principle of positive displacement. When the plunger is depressed, it creates pressure that forces the fluid through the barrel's outlet. The smooth inner surface minimizes friction, while the calibrated markings allow precise volume measurement. The barrel maintains structural integrity under pressure to prevent leakage or deformation during operation.
材料
Medical-grade polypropylene (PP)polycarbonate (PC)cyclic olefin copolymer (COC)or glass (borosilicate). Materials must meet USP Class VIISO 10993or FDA 21 CFR Part 177 standards for biocompatibility and chemical resistance.
