Catalog Number - 58807-Z32

58807-Z32 MICROSOLV Pouring Rings are durable polypropylene inserts designed for GL32‑threaded mobile phase reservoir bottles, improving control when decanting liquids in HPLC, UHPLC, LC‑MS, and general laboratory workflows.

These natural‑colored drip rings guide solvent flow during pouring, helping reduce drips, splashing, and solvent loss—especially important when working with smaller volume bottles.

The design allows the ring to fit deeper into the bottle opening, providing a more secure hold and minimizing the risk of dislodging during use.
