know more about plastic syringe

First of all, the current perfusion device is mainly made of glass material and plastic material. The plastic perfusion device is gradually replacing the glass syringe. The main cost is lower, the safety is higher than that of the glass syringe, and it is not easy to be broken. The production process of the perfusion device 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 sealing requirements of the perfusion product are high. When selecting the perfusion device, the sealing property should be tested. Half of the water is injected into the perfusion device, the piston is inserted into the syringe, the protective cap is removed, and the residual air is removed. Block with the cap and apply an axial pressure of 30 N on the pusher plug inside the syringe through the push rod for 30 seconds. There should be no leakage at the cap seal and the piston seal.

Third, the plastic syringe 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 higher sterility. Additional requirements for ethylene oxide sterilization or cobalt 60 irradiation sterilization are required.
