Overview

The PTFE module is similar to the standard Flow module*, QFM 401, but the titanium flow part is replaced by PTFE. It has proven to be useful for plasma samples containing components that normally would interact with, and aggregate on, titanium.

The standard configuration includes Viton O-rings, but this can be upgraded to Kalrez to enable work with more harsh chemicals.
