Aijiren’s Bonded Cap & Septa series (Part No. SC9192–B‑SC92291‑A) delivers 9 mm threaded vial caps with high‑strength seals, chemical‑inert multilayer construction, and color‑coded identification. These caps prevent leaks under extreme conditions, resist solvent attack, and streamline sample handling in chromatography, storage, and high‑throughput workflows.

HPLC Syringe Filters are essential tools for chromatography and lab sample preparation. They precisely remove particulates to protect columns and prevent clogging, while low‑leach housings preserve sample purity. Available membrane materials include Nylon, PVDF, PTFE, PES, MCE, PP, and Cellulose Acetate—suiting pharmaceutical, environmental, biotech, and food‑testing workflows.

Designed for precision labs, 24-400 screw neck vials meet EPA and TOC analysis standards, available in 20mL to 60mL volumes for trace contaminant detection and long-term sample storage.

Aijiren’s Micro Vials & Caps series are designed for High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC) analyses. Made from high-quality borosilicate glass, they ensure sample stability and accurate analytical results.
