May 20 , 2019

How can we correctly identify the quality of plastic syringe products? Let's know more from syringe factory.

Currently, plastic syringes are mainly made of glass and plastic. Plastic syringes are gradually replacing glass syringes. They are mainly low in cost, high in safety relative to glass, not easy to break, and the production of high quality syringe products. The process itself is relatively advanced, and the infusion device is generally produced by an injection molding process. The products produced by the injection molding process are molded at one time without any scraps, and the products are accurate in size and uniform in weight.

Secondly, the plastic syringe has high sealing requirements. When selecting the syringe, the sealing property should be tested. Half of the water is injected into the syringe, the piston is inserted into the syringe, and the protective cap is removed to remove residual air. Then use the cap to block, apply an axial pressure of 30N on the pusher plug inside the syringe through the push rod for 30 seconds, and there should be no leakage at the cap seal and the piston seal.

Third, plastic syringes must be guaranteed to be sterility due to direct contact with the drug. Generally, the syringe should be produced in a clean workshop that meets national standards. In addition, in order to ensure sterility, if the veterinary drug manufacturer has sterility For higher requirements, additional ethylene oxide sterilization or cobalt 60 irradiation sterilization may be performed.
