SilTite µ-Unions

Making Joining Matter

Your chromatography analysis does not end with the selection of the GC column. The combination of components selected for your instrument also make an important contribution to successful separations.

The range of GC connections improves your chromatography. Poorly defined or selected connections can lead to an increase in dead volume, leaks from cycled temperatures and mismatched tubing sizes.

SilTite® µ-Unions are specifically designed and precision engineered for use in capillary GC.

Features and benefits

  • Inert - Enabled by our expertise in surface chemistry, features chemically deactivated stainless steel ferrules alleviating active sites.
  • Zero dead volume - Giving you optimized peak shapes.
  • Robust - Stable for both extreme temperature and pressure cycling.
  • SilTite FingerTite technology - Ensures it’s easy to install and leak free.
  • SilTite ferrules - No more leaks and no need to re-tighten after installation.
  • Only 9 mm in total length and a mass of <0.5 g - Low thermal mass.

Recommended applications

  • Fitting a pre-column.
  • GC x GC connections.
