All syringes are not guaranteed to be industrial grades including silicones and chlorides, use embedded, no loose edges, no rise, no bubbles
The inner layer is closely matched with the piston to ensure that the discharged liquid drops, and the thickness of the inert PP material wall does not burst, and the chemical is not easy to function.
Inert PP material is used together with the piston, and the double-packing knife design ensures that it can be matched with the syringe to ensure that no liquid is tightly stored and widely used.
