9mm Screw Closures

9mm Screw Closures is a very popular product of Aijiren, because its matching 9mm hplc vial is often used in autosamplers, the most common type of product, so the sales are very high, and the sales of the matching 9mm closures are also very high. The 9mm screw neck cap is made of high-quality polypropylene. Septa is compounded with silicone and PTFE. PTFE is extremely inert and suitable to be placed on the side facing the sample. The hardness and non-deformation of silicone ensure that the septa is automatically injected by the needle. After the puncture, the air pressure can be restored to ensure air tightness.

Aijiren provides HPLC vial closures via septa with caps. The combination of PTFE and silica gel has the ability to protect and reseal, so it is suitable for our autosampler vials. The 9 mm closure includes a septum made of polypropylene cap, PTFE and silicone, with a central hole in the middle. Aijiren provides septa and slit septa. PTFE/silicone septa are most commonly used in HPLC applications, and pre-slit septa are easier to pierce with a needle. The cap color is generally transparent or blue, and other special colors can also be produced accordingly. Because it is pre-installed with caps and septa, it is more convenient for experiments, saves preparation time, and can also reduce pollution in the preparation process.
