Prefilled syringes, as a simple pharmaceutical packaging material, occupy an increasing share in the aseptic pharmaceutical packaging market, and the quality of domestic prefilled syringes is constantly upgrading.

According to the experimental method stipulated in the relevant standards: take an appropriate amount of this product, connect the push rod and the piston, fully insert the piston into a prefilled syringe lubricated with silicone oil and filled with half of water, remove air, and insert a needle on the syringe With the protective cap, slowly withdraw it back for a distance of about 3mm. The push rod should remain stable and should not be separated from the piston.

The significance of the compatibility test between the plunger and the push rod of the prefilled syringe:

When the prefilled syringe is used clinically, the medicine can be directly opened and used when the medicine is preset in the injection container, which reduces the extraction from the container and can effectively avoid the potential hazards of glass shards and secondary pollution in the air. However, the compatibility between the piston and the push rod plays a very important role in the injection process, so it is of great significance to use professional laboratory testing equipment to detect the compatibility between the piston and the push rod of the prefilled syringe.
