Pump Supplies
The Agilent 1100/1200 Series of HPLC modules has several different pump units to choose
from: isocratic, quaternary, binary, capillary, nano, and preparative. The 1100/1200 was
designed for ease of use – all pump maintenance parts can be accessed from the front by
simply removing the front cover. Scheduled routine maintenance of these pumps based on
your application is recommended to achieve maximum uptime.
1100/1200 Pump Routine Maintenance Procedures
• Replace the seals and pistons
• Replace the PTFE frit
• Replace the cartridge in the Active Inlet Valve
• Clean the outlet ball valve
• Clean or replace the solvent inlet frits
Routine pump maintenance should be done on a regular basis to keep your Agilent
1100/1200 system performing at its optimum. You may perform all the maintenance at once
or perform maintenance on an as-needed basis. Some parts may need to be replaced more
than others depending upon your application and solvent preparation procedures.
Seal Wash
The routine use of highly concentrated buffer solutions (100 mM) will reduce the life of the
seals and pistons in your 1100/1200 Series pump. You can counteract the problem with one
of our seal wash kits, which flushes the backside of the seal with a wash solvent;
water/isopropanol (90/10) is recommended as the wash solvent. The continuous seal wash
uses gravity to flow the wash solvent, and is compatible with 1100/1200 standard and
capillary pumps. The active seal wash uses a peristaltic pump to flow the wash solvent, and is
compatible with the 1200 Series pump and 1100 pumps with serial numbers DE40906378,
DE40926032, DE40914884 and higher.
