- Connect a guard column to an analytical column.
- Connect a column to a transfer line.
- Connect two columns in series.
- Repair a broken column.
The Vu2 Union™ connector is a Press-Tight® connector that incorporates two ferrules to make secondary seals between the column ends and the glass insert in the connector. Each knurled nut applies independent pressure to each ferrule, to make a leak-free seal with the column end. The open design allows you to visually confirm the presence of a seal at the column-glass insert connection. The columns cannot unexpectedly disconnect during temperature-programmed analyses, even at temperatures as high as 400°C.
Accommodates Restek’s Universal Press-Tight® connectors: Fits Restek and other columns from 0.33-0.74mm O.D. (0.1mm-0.53mm I.D.). Kit includes Vu2 Union, two knurled nuts, two Press-Tight unions and four ferrules.
