HPLC Bottle Safety Caps — 3 Port & 4 Port

The HPLC Bottle Safety Caps (MSSC) are multi-port caps designed for standard GL45 solvent reservoir bottles used in HPLC and UHPLC systems. Available in 3-port and 4-port configurations, these caps allow multiple tubing connections through a single sealed cap while preventing solvent evaporation and minimizing laboratory exposure to hazardous vapors. Each port accommodates 1/8" OD tubing for pump inlet lines, degassing gas lines, bottle-top filters, or spare connections. The caps help maintain a closed, contamination-free solvent delivery system while improving laboratory safety and operational efficiency.
