PP Safety Caps (HPLC)

PP Safety Caps (HPLC) are specialized screw caps made from polypropylene (PP) designed for High-Performance Liquid Chromatography (HPLC) systems. These caps are engineered to securely seal solvent reservoirs while allowing for safe and efficient tubing connections. Their main functions are to prevent evaporation, minimize contamination, and control solvent vapor exposure, ensuring a safe, closed system for both users and the environment. These caps typically feature multi-port connections (1–4 channels) for PTFE tubing, as well as a one-way air inlet valve or integrated filter to maintain pressure balance while preventing dust, moisture, or microbial ingress. PP Safety Caps for HPLC are compatible with GL45, GL38, or GL80 neck-threaded bottles, and are designed for chemical resistance, durability, and compliance with safety regulations in pharmaceutical, analytical, and chemical laboratories.
