1.Look at the appearance
Qualified plastic syringes must first look at their appearance, overall shape, comfortable color tone, consistent color, smooth and smooth surface, no deformation, burrs and obvious scratches, smooth inner wall of the sleeve, no corrugation, and flat and smooth head of the syringe, The push rod and the sleeve have a good fit.
2.Test the seal
Pharmaceutical packaging has high requirements for tightness, and dial a dose syringes are no exception, and their tightness should be tested when choosing a syringe. Detection method: inject half of the water into the syringe, insert the piston into the syringe, remove the protective cap, remove the residual air, and block it with the protective cap. Apply an axial pressure of 30N on the plunger rubber plug inside the syringe through the push rod. Keep it for thirty seconds, and there should be no leakage at the seal of the protective cap and the seal of the piston.
3.Sterilization
Since plastic syringes are in direct contact with drugs, their sterility must be ensured, so the production environment of the product is very important. Generally, the syringe should be produced in a clean workshop that meets the national standards, and has been sterilized by ethylene oxide. The ethylene oxide sterilization indicator card changes from red to blue to indicate complete sterilization.
