13mm Screw Neck Closures

Aijiren produces Closures that are compatible with Autosampler Vials and Headspace Vials, including COD Test Tubes, for sealing and sampling. Such Closures usually have a cap that is easy to seal, and Septa is soft and easy to puncture. There are different types and sizes. Aijiren produces these The goal is to better carry out the application of Vias.

Aijiren has been producing 13mm Screw Thread Cap for 20 years. Aijiren uses high-quality raw materials and skilled production technology to ensure the quality of 13mm Screw Thread Cap. Aijiren has become a well-known supplier of chromatography consumables in China, and Aijiren will continue to Work hard and strive to become a world-renowned chromatographic brand.

The screw cap that comes with the 13mm screw neck cap has knurling on the side, which provides excellent grip and comfort when laboratory personnel use the vial. The silicone rubber/PTFE septa used with the 13mm screw cap is designed to provide adequate resistance to the autosampler needles during sample injection so that they can penetrate the sample vial correctly without damaging the septa or the injection needle. Too much or too little needle resistance will damage the septum and affect resealing. It is also possible that the needle will be blocked due to the core of the septa material, and even the autosampler may be damaged. These septas produced by Aijiren can work even when using a variety of needles: fine needles, blunt needles and even blunt needles. When using aijiren 13mm screw caps, even after multiple injections, the sample or solvent evaporation performance is low.

Compared with Silicone, PTFE has a soft texture, strong gloss, and very high inertness. Most chemicals will not react with PTFE, so it is very suitable for the side facing the reagent in the Vial, even if it is shaking, the sample Exposure to Septa will not affect the contents of the sample. These two materials use Aijiren’s exclusive compounding process, which can be compounded into a double-layer septa without adhesives, ensuring the safety of sample injection.
