The GenPure Ultrapure Water System requires regular maintenance to ensure high-quality water output and system reliability. This article covers part numbers for preventive maintenance including the ultrapure cartridge, sterile 0.2 micron filter, ultrafiltration membrane, and UV-lamp and the recommended replacement intervals. Cleaning and disinfection should be conducted at least annually.

Genpure Preventive Maintenance Intervals

Issue:

Determining the appropriate preventive maintenance intervals for the Thermo Scientific Barnstead GenPure Ultrapure Water System to ensure optimal performance and determining the correct part numbers for PM components.

Environment:

  • Product: Thermo Scientific Barnstead GenPure Ultrapure Water Systems
  • Component Part Numbers (not all systems feature UV and UF. Check your specific model):
    • Ultrapure Cartridge (Part Number 09.2005)
    • Sterile 0.2 Micron Filter (Part Number 09.1003)
    • UF Ultrafiltration Membrane (Part Number 50133980)
    • UV-Lamp (Part Number 09.2002)

Resolution:

  1. Ultrapure Cartridge:

    • Replace up to every 12 months or when the ultrapure water limiting value is exceeded, whichever is shorter.
    • Longer usage can result in bacterial growth on the resin.

  2. Sterile 0.2 Micron Filter:

    • Replace up to every 12 months or when the flow rate becomes noticeably slower.

  3. Ultrafiltration Membrane:

    • Replace up to every 24 months or if there is endotoxin breakthrough in product water or when the water flow rate becomes markedly slower.

  4. UV-Lamp:

    • Replace up to every 24 months or unless the system indicates the lamp needs to be replaced.

  5. General Maintenance:

    • Cleaning and disinfection should be performed at least once yearly, or when the ultrapure cartridge is replaced, or when bacteria is present in the product water.
    • Regular servicing of the system ensures that the quality of water is maintained.
    • It is recommended to have a service contract with a factory-authorized service company to ensure proper maintenance.
    • The life of consumable materials is directly dependent on the quality of the feed water and the amount of water used daily.
