Cap, Mobile Phase Delivery, Replacement. Blue, GL45 Threads and Open Hole. ARE-Applied Research brand. 5/PK.
Additional Info:
58820-10-005 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 versatile system integration options.
The open‑hole design allows for tubing access while maintaining a secure fit, making these caps ideal for replacement, system customization, or spare inventory in active labs.
