China 15-425 Thread Caps with Septa Manufacturer
15-425 black screw pp cap has a 15mm outer diameter, which means it is compatible with vials that have a corresponding neck size and threading. These caps are typically made from high-quality materials such as polypropylene. These polypropylene caps have excellent sealing characteristics and offer good chemical resistance including acids, alcohols, alkalis, aqueous products, cosmetics, and household oils. Polypropylene Hole Caps are known for good impact strength, cost-effectiveness, and pliability.

The screw pp caps come equipped with septa. Septa is sold separately. Septa are thin, flexible, and typically made of materials like silicone, PTFE (polytetrafluoroethylene), or a combination of materials. Septa acts as a barrier between the sample and the external environment, preventing contamination and evaporation. PTFE/Silicone septa are the preferred product for use in most HPLC and GC applications where resealability and high purity are critical. Septa-silica gel has strong repetitive sealability, and it can maintain good close performance after multiple injections; PTFE is a material with better chemical conditions at present, and it can withstand strong acids and alkalis. Two materials After compounding, the bottle can be used for various laboratory purposes such as sealed sampling, chemical storage, and so on.
