Press-Fit Connectors allow you to simply connect, with a tight seal, different columns or Retenetion Gaps in many ways. Altmann Press-Fit connectors are universal to fit any tubing size. Available as linear 2-ways union (to connect two columns or a Retention Gap to the analytical column), or 3-ways/Y-union (e.g. ideal to connect two columns to a single injector - double detector GC configuration) or personalized Multiwas connectors for advanced analytical system configurations as MD-GC and other custom settings.
