Vu2 Union Connector, Fits Column ID 0.18/0.28 mm

Restek Vu2 Union Connector, Fits Column ID 0.18/0.28 mmRestek’s Vu2 Union connector combines the simplicity of a Press-Tight union with the strength of a metal union.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.Kits include: Vu2 Union body, two knurled nuts, two Press-Tight unions, and four ferrulesNote: This product is not recommended for GC column-to-MS connections.- Connect a guard column to an analytical column.- Connect a column to a transfer line.- Connect two columns in series.- Repair a broken column.- Fit both Restek cage designs.

Connector Kit, MXT connector for 0.25mm ID Fused Silica Columns

MXT-Union Connector Kit for Metal and/or Fused Silica GC Columns, 0.25 mm ID

Restek MXT-Union Connector Kit for Metal and/or Fused Silica GC Columns, 0.25 mm IDThese MXT connectors can be used with fused silica tubing because of a Valcon polyimide, 1/32-inch, one-piece fused silica adaptor. This unique graphite-reinforced composite allows a capillary column to slide into the adaptor and be locked in place simply by loosening and tightening the fitting. Each kit contains the MXT union; two 1/32-inch nuts; and two, one-piece, fused silica adaptors.- Low dead volume, leak-tight connection.- Reusable.- Siltek treatment ensures maximum inertness.- Ideal for connecting a guard column or transfer line to an analytical column.- Use to oven temperatures of 350 °C.- Can also be used for connecting fused silica to metal.

Connector, Kit SilTite MicroUnion to connect 0.18/0.25mm to 0.18/0.25mm ID Columns, ea.

Connector, SilTite µ-Union, 0.18/0.25-0.18/0.25 mm ID, for Standard Columns

Restek Connector, SilTite µ-Union, 0.18/0.25-0.18/0.25 mm ID, for Standard ColumnsPress-fit style connectors work well for many applications, but the connector seal can be broken by extreme temperature and pressure cycling. In these situations, SilTite μ-Unions are a better alternative as they create a permanent connection between analytical columns, guard columns, and retention gaps. SilTite FingerTite technology provides easy installation and a reliable, leak-tight connection. Data quality can be improved by using these connectors because their zero-dead-volume design and deactivated metal construction ensure optimal peak shapes. Robust SilTite μ-Unions are recommended for mass spectrometry work and any application with extreme temperature and pressure changes. Connector kits are available in six configurations that are designed to securely connect columns of either the same or different inner diameters. Each kit contains two SilTite µ-Union connectors, five double-taper ferrules, and installation tools.When connecting columns of different inner diameters (ID), always connect the column with the largest ID first. The ferrules are very small, making it difficult to see the size difference between the two ferrule orifices and making it easy to install the smaller ID column into the wrong orifice. Since the larger ID column (e.g., 0.32 mm) will not fit into the smaller ferrule orifice (e.g., 0.25 mm), installing the larger column first ensures the correct end of the ferrule will be used for both columns.- Reliably create permanent connections between fused silica analytical columns, guard columns, and retention gaps.- SilTite FingerTite technology provides easy installation and a permanent leak-tight connection.- Deactivated metal and zero-dead-volume design ensure optimal peak shapes.- Robust connection is stable through extreme temperature and pressure cycling, making it ideal for use with mass spectrometers.- Kits contain two SilTite µ-Union connectors, five double-taper ferrules, and installation tools.
