> Pulse-free pump


Expandability is the keyword for the 700 Series.

Extra pumps and detectors can be added as necessary. The standard configuration includes the ECD-700 detector equipped with one amperometric cell, the EP-700 pump unit with one microflow pump installed, and the ATC-700 temperature control unit, The pump unit also has a two channel solvent degasser built in.
