Cap, Mobile Phase Delivery, Replacement. Blue, GL45 Threads and Open Hole. ARE-Applied Research brand. 10/PK.
Additional Info:
58820-10-010 ARE‑Applied Research Replacement Caps are polyethylene GL45 open‑hole screw caps designed for mobile phase delivery systems and solvent bottle assemblies used in HPLC, UHPLC, LC‑MS, and general laboratory workflows.
These caps are specifically engineered to accept PTFE inserts used in the Mobile Phase Delivery Cap (58820‑06) or to be used independently with filter degassers and standard taper adapters, providing flexible system configuration options.
The open‑hole design allows for routing of tubing while maintaining a secure fit, making these caps ideal for system replacements, upgrades, or spare inventory in active laboratories.
