Judging the quality of plastic veterinary syringes

There are many types of plastic veterinary syringe products, and the quality is different. So how can we correctly distinguish the product quality of plastic veterinary syringes?

Now do the following brief analysis based on some of its characteristics:

First of all, the current syringes are mainly made of glass and plastic. Plastic syringes are gradually replacing glass syringes. They mainly have lower cost, higher safety than glass syringes, and are not easily broken. The production process itself is relatively advanced. Generally speaking, it is produced by injection molding. The products produced by the injection molding process are formed in one shot, without scraps, and the product dimensions are accurate and the weight is uniform.

Second, the tightness of plastic syringes is high. When selecting the syringe, the tightness of the syringe should be tested. Fill the syringe with half of the water, insert the piston into the syringe, remove the protective cap, and remove the remaining air. Block with a protective cap, apply axial pressure 30N on the push rod rubber plug inside the syringe through the push rod, and keep it for 30 seconds. There should be no leakage at the protective cap seal and piston seal.

Third, because the pre-filled syringes are in direct contact with the drug, they must ensure their sterility. Generally, they should be produced in clean workshops that meet national standards. In addition, to ensure their sterility, If required, additional ethylene oxide sterilization or cobalt 60 radiation sterilization can be performed.
