Welch 1420H-14 Dry Ice / Isopropanol Cold Trap with 1/2" Inlet/Outlet

Welch 1420H-14 isopropyl cold trap represents an effective device for applications with Schlenk Lines or vacuum manifolds. The three-quart (2.8 l) inner well for refrigerants is capable of trapping up to 1.5 l of condensate. Depending upon the load and the type of refrigerant, the utility maintains cold temperature from 2 (with IPA) to 12 hours (with dry ice).

Features

• superior for applications with vacuum manifolds, freeze dryers, concentrators, etc.;
• trapping surface is easy-to-clean due to the removable center element;
• employs two types of refrigerants – IPA or dry ice.

Providing the superior pre-pump protection, it ensures the proper performance and prolongs its service life.
