Page 20 of 32
5. Performance verification
The accuracy of the vacuum provided by the
pump can be easily checked at any time,
however this verification is not mandatory.
Materials:
1. Sanitization kit (item MMSANKIT1)
2. Consumables for sanitization kit
(item MMSANSYFU)
3. Milliflex Oasis
®
vacuum gauge for pump
verification testing (item MMGAUGEMM)
• This item is provided in the sanitization
kit or can be purchased separately (it
comes with a certificate of calibration).
4. Stopwatch
5. Purified water
• Remove the pump head
• Place the sanitization kit on to the pump
head support and lock it
• Lock the sanitization kit plug on the other
support
• Rotate the trigger clockwise, the switch
turns white
• Place sanitization funnel assembly
(sanitization kit consumables) on the
sanitization kit
• Connect the Milliflex Oasis
®
vacuum gauge
to the syringe port of the kit

Internal flow prewetting step:
1. Open the funnel lid, pour purified water up
to the 250 mL indication level, put back
the lid on place
2. Touch the switch to start the filtration
3. Stop the filtration when it is complete
4. Disconnect the vacuum gauge to reset it
and connect it back to the syringe port of
the kit
Verification of the vacuum level and
verification of the flow time:
5. Again, open the funnel lid, pour purified
water up to the 250 mL indication level,
put back the lid on place
6. Start the stop watch and simultaneously
start the filtration by touching the switch
7. Record the vacuum level on the gauge
and the time needed to complete the
filtration
8. Stop the filtration when there is no more
water
9. Disconnect the vacuum gauge to reset it
and connect it back to the syringe port of
the kit
10. Repeat steps 4 to 9 twice more
Check that the average values are within the
following specifications.
Pressure Filtration time
< –0.4 bars ≤ 25 seconds for 250 mL water
• Remove the sanitization kit and clean
it using a wipe moistened with a
surface sanitizer listed in the cleaning &
maintenance section
