Additional Info:
58820-06 ARE‑Applied Research Mobile Phase Delivery Cap is a complete GL45 solvent delivery cap system designed to maintain mobile phase purity and system integrity in HPLC, UHPLC, and LC‑MS applications.
This cap assembly is commonly used in laboratories to help ensure compliance with Good Laboratory Practice (GLP) by preventing contamination of mobile phase solvents during use and storage.
The integrated PTFE insert with three holes, along with a PEEK plug and O‑ring, allows secure and flexible routing of solvent lines while maintaining a sealed environment.
Because the mobile phase only contacts medical‑grade PTFE, there is:
No contamination from plastics or liners
No leaching or extractables from cap materials
High purity solvent delivery
✅ Explore compatible plugs for this cap system
Contamination Control – GLP‑Focused Design
Sealed system minimizes exposure to air and contaminants
Prevents dust and particulates from entering the bottle
Reduces solvent degradation from atmospheric interaction
Helps maintain analytical consistency
✅ Supports GLP compliance and reliable analytical results
PTFE / PEEK Flow Path – High Purity Solvent Contact
PTFE insert ensures chemically inert contact surface
PEEK plug provides secure, chemically resistant sealing
Eliminates risk of contamination from common cap materials
✅ Ideal for sensitive analytical and LC‑MS workflows
