the 600E Pump
This chapter describes the procedures for making fluidic connections to the 600E pump.

2.1 Selecting and Installing Fittings

The Waters 600E Multisolvent Delivery System Startup Kit includes a variety of tubing
and fittings to facilitate connections between the 600E pump and an external autosampler,
column, and detector. Refer to the startup kit list for information.
This section describes:
• Cutting tubing
• Installing connectors and fittings
Tubing Considerations
Observe the following rules when installing tubing and fittings.
Caution: When handling eluents, changing tubing, or operating the 600E Multisolvent
Delivery System in general, always observe good laboratory practices. Know the physical
and chemical properties of the eluents. Refer to the Material Safety Data Sheets for the
eluents in use.
• Before loosening a fitting, stop the pump flow. Vent any pressure in the flow path
with the reference valve or allow pressure to decay to zero.
• Minimize dead volume by using the appropriate tubing for each location. Cut the
tube following the method described in this section, and install the fittings as
Caution: Do not attempt to relieve pressure by loosening a fitting.
Attempting to do this with the system operating under high pressure may
cause eluent to spray.
