Significance of fitting detection of plastic syringe

The experimental method specified in the plastic syringe assembly (with injection needle) standard: take the appropriate amount of the product, connect the push rod and the piston, and insert the piston completely into the plastic syringe that has been lubricated with silicone oil and filled with half of water. Inside, remove the air, insert a needle cap on the syringe, and slowly withdraw back about 3mm. The push rod should be stable and should not be separated from the piston.

The significance of the compatibility test between the  syringe plunger;

When the plastic syringe is used in clinical use, the medicine can be directly opened and used in the injection container, which reduces the extraction from the container, and can effectively avoid the potential hidden trouble of the glass swarf and the secondary pollution in the air. However, it plays an important role in the process of injection of the matching value between the piston and the push rod. Therefore, it is of great significance to use professional laboratory testing equipment to detect the compatibility of the pre-filled syringe piston with the push rod.
