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 360°C.
• Available in union and “Y” configurations.
• Can also be used for fused silica to metal connections.
These MXT™ connectors can be used with fused silica tubing,
because of a Valcon polyimide

-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.
Valco™ Connectors—One-Piece Valcon Polyimide
Adaptor Ferrule for Fused Silica
Fused silica adaptor ferrules are Valcon polyimide, a unique
graphite-reinforced composite, specially prepared to maximize
mechanical stability at temperatures to 350°C. The determining
factor for selecting adaptor ferrule size is the fused silica
tubing OD.

Low-Dead-Volume Connector Kits for Metal
Columns
These low-dead-volume connectors are Siltek® treated to make
them inert to active compounds, just like our MXT® columns.
They can be used at temperatures up to 430°C without degrad-
ing the deactivated layer. Purchase the appropriate ferrules for
connecting 0.28, 0.32 or 0.53mm ID tubing.
MXT™ Low-Dead-Volume Connector
Kits for Metal Columns
• Connect a guard column/transfer line
to an MXT® stainless steel column.
• Low thermal mass tracks rapid oven
temperature programming.
• Stainless steel ferrules and nuts.
• Available in “Y” and union
configurations.
• Siltek® treatment ensures ultimate
inertness.
Each kit contains the MXT™ union, two
