At present, there are various types of pre-filling syringes on the market, with different quality. So how can we correctly identify the quality of pre-filling syringes? Now according to some of its characteristics do the following brief analysis:

First of all, the current preliminary potting syringes are mainly of glass and plastic, plastic injector in gradually replace the glass syringes, its main has lower cost, relative to the glass with higher safety, not easily broken, more high quality syringes product the production process itself is more advanced, generally syringes was produced by injection molding process. Injection molding process produced by the product one-time molding, no waste, product size accurate, even weight.

Prefill the syringe

Second, sealing the demand is higher, in the process of the potting syringe in selecting syringes should the sealing test, within the syringes into half water, insert the piston syringe, remove the protective cap, remove residual air, with a protective cap block, through the push rod inside the syringe putter glue 30 n axial pressure, keep thirty seconds, protecting cap seal and piston seal should be no leakage.

Thirdly, due to direct contact with drugs, the sterile quality of the preperfusion syringe must be guaranteed. Generally, the perfuse device should be produced in a clean workshop meeting national standards. In addition, in order to ensure its sterile quality, if the veterinary drug manufacturer has high requirements on the sterile quality, additional ethylene oxide sterilization or cobalt-60 irradiation sterilization can be carried out.
