20mm Crimp Top Aluminum Caps with Septa

Aijiren has over 16 years of experience in manufacturing chromatography consumables. Our 20mm aluminum crimp caps are primarily designed for use with headspace vials, requiring a compatible crimping tool for sealing. Featuring excellent sealing properties, they effectively prevent external air, moisture, and impurities from entering the vial, thereby preserving the freshness and quality of the internal liquid. Constructed from aluminum, these caps exhibit excellent corrosion resistance, ensuring stability in various environmental conditions and minimal susceptibility to external chemical influences. This product's magnetic properties make it highly beneficial for use with magnetic-sealing gas chromatographs, contributing to their accuracy and efficiency.
