D2EPC-1 - Unique Design

The design of the D2EPC-1 is very flexible. By using a small and versatile manifold, without built in restrictors, virtually every EPC configuration can be created using the same hardware. This is how we do this:

Input and output restrictions are housed in screw-on tube fittings

Control range is configured by using different restrictions in screw-on tube fittings

Manifold is almost identical regardless of flow or pressure channel choice

Flow direction can be reversed because of symmetrical manifold

Various tubing connection standards can be used due to screw-on fitting design

 

D2EPC-1 - Possible Configurations

All common configurations used in GC and other Analyzer Instruments can easily be reaslized with the D2EPC-1
