Cleaning Body and Pump Head
• May be wiped down with a towel moderately soaked in the following common laboratory sanitizing solutions:
•70% isopropyl alcohol (IPA)
•10% bleach
Sanitizing the Fluid Path
• The Fluid Path should be changed at least once a week.
•For optimal contamination control, daily replacement of Fluid Path is recommended.
• Upon initial installation of the Fluid Path:
•Run 70% IPA through the Fluid Path for 5 seconds
•Pump residual IPA through the tube
• If the Fluid Path is used for more than one day:
•At the end of the filtration session, run 70% IPA through the Fluid Path for 5 seconds
•Pump residual IPA through the tube
•Open the pump head loading door to relieve the pinch of the rollers on the drive tube
