Agilent 7100 Capillary Electrophoresis System User Manual 185
Hardware Information 7
External Water Bath for Tray Cooling (Optional)
Minimum differential pressure of 150 mbar, and
Maximum pressure of 500 mbar.
• Requirements for pressure pump:
A pump with the capacity to generate a differential pressure of at least
0.15 bar. For a single action pump, a high pressure capability of 0.15 bar is
required. The high pressure must not exceed 0.5 bar and the low pressure
must not exceed -0.5 bar.
• Cooling liquid:
Distilled water plus a maximum 3 % anti-freeze.
• Bath temperature:
The minimum allowed temperature is 1 °C and the
Maximum allowed temperature is 50 °C.
Connecting an External Water Bath
• The startup kit supplied with the Agilent CE instrument includes two
fittings for flexible tubing with 8 mm internal diameter. Use those fittings
for the flexible tubing used with your external water bath.
• Connect the fittings to the connectors on the instrument (see Figure 2 on
page 59). Use the upper connector for incoming liquid, the lower connector
for outgoing liquid.
Make sure both the water bath and the Agilent CE instrument are switched off
when installing the external water bath.
Risk of liquid spill and instrument damage
Higher pressure might lead to liquid leakage inside and outside the instrument.
Elevated temperatures might lead to deformation and leakage of the tubing system.
Liquid spillage can damage electronic components of the instrument.
• Do not use a water bath with more than 0.5 bar pressure.
• Do not use liquids at temperatures above 50 °C.
