How does a Vu2 Union connector work?
A Press-Tight union in the Vu2 Union connector joins the fused silica tubing ends together; the ferrule and knurled nut at each end of the connector hold the tubing in place via a secondary seal between the ferrule and the Press-Tight union. Each knurled nut applies independent pressure to each ferrule to make leak-tight seals with the column ends. These ultra-strong connections will not unexpectedly disconnect under temperature changes, vibrations, or other stresses normally encountered in GC analyses. The open design allows visual confirmation of the seal between the column and the Press-Tight union to ensure confidence in the connection. Hang the connector from the column cage to minimize stress on the connections.
Who will benefit from using Vu2 Union connectors?
Any analyst using guard columns, transfer lines, or restrictor tubing; performing a dual-column analysis with columns connected in series; or seeking to repair a broken column will find Vu2 Union connectors the simple, reliable, easy-to-use solution to their connection needs.
NOTE: This product is not recommended for GC column-to-MS connections.
