Filta-Max xpress Operator’s Guide
Maintenance and cleaning
Follow the guidelines below when decontaminating the Filta-Max xpress system.
After each elution
• Clean the QC stem on the Filta-Max xpress Elution Station using an alcohol-soaked wipe or
equivalent.
• Decontaminate the sampling kit, outlet diverter fittings, and the Filter Housing by soaking
them in warm (40°C–60°C) water containing laboratory-grade detergent for 15–30 minutes.
Then manually clean the equipment using a bottle brush or similar device, and rinse with (oo)
cyst-free finished water and then with reagent-grade water.
• Should more stringent decontamination be required, equipment may be soaked for 30
minutes in a 6% solution of sodium hypochlorite (60 mL of household bleach in 1 L of water).
Then manually clean the equipment using a bottle brush or similar device, and rinse with (oo)
cyst-free finished water and then with reagent-grade water.
• Relubricate and/or replace all O-rings, as required.
On a daily basis
• Clean the surfaces of the Filta-Max xpress Pressure Elution Station with laboratory disinfectant
or alcohol-soaked wipes.
• Clean the metal base plate and back plate (inside the door) using laboratory disinfectant or
alcohol-soaked wipes. Keep the inside of the machine as clean and dry as possible; remove
any spills between samples.
Note: With the air supply turned off, you can raise the collection vessel holder to improve
access to the base plate.
On a monthly basis
If the Pressure Elution Station is not used for 2 weeks, then you should also clean the pressure
chamber, following the steps below. The following tools are required and are supplied with each
Filta-Max xpress Pressure Elution Station as part of the accessory kit:
Angled screwdriver
