Waters In-Line Degasser AF

The Waters In-Line Degasser AF provides HPLC systems with an automatic, continuous method for removing dissolved gasses from mobile phases. The continuous running pump cycles between high-speed, to provide rapid vacuum pull-down, and low-speed, to sustain a consistent vacuum level. This unique approach enables rapid vacuum equilibration for faster eluent equilibration. The In-Line Degasser AF's continuous operating mode improves chromatographic performance for high-sensitivity applications by eliminating detector baseline drift caused by pump hysteresis in discontinuous operating modes.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Included with the Waters In-Line Degasser AF:
Includes: > Power Cord > Operator's Manual > Full 90 Day Parts and Labor Warranty
