18mm Screw Neck Closures

Aijiren’s Septa made of high-quality raw materials can protect the seal inside the Vial to a certain extent, and will not break or fall off the cap after the automatic injection needle is punctured. This is to a large extent. Gas chromatography experiments provide convenience, and bring safe and accurate results.
