· To meet the needs of high-sensitivity and high-viscosity preparations, a new-generation COP prefilled syringe has been developed based on the original design of the glass prefilled syringe in combination with new materials.

· Meet the requirements of high-sensitivity preparations: Free from silicone oil system (optional) and tungsten, few leachable and extractable, low protein adsorption, and excellent drug compatibility.

· Meet the requirements of high-viscosity preparations: The needle and the syringe barrel are integrally formed to prevent the needle from falling off and reduce the risk of liquid leakage; high mechanical strength, impact resistance, high transparency, good exquisiteness and beauty, environmental protection, and multiple sterilization methods.
