MXT™-Union Connector Kits for Fused Silica Columns
• 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.
• Available in union and “Y” configurations.
MXT™-Union Connector Kits for Fused Silica Columns
These 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.
