3. Testing
The following components are needed
before starting your sample processing:
• Milliflex Oasis
®
pump installed following
the installation section
• Milliflex Oasis
®
filtration units
• Milliflex Oasis
®
media plates
• Samples to test
Ensure that the internal pump flow was
sanitized according to the cleaning &
maintenance section.
• Clean the exterior of the pump using a
wipe moistened with a surface sanitizer
listed in the cleaning & maintenance
section
3.1 Filtration units
Different types of filtration units are
available (see ordering information section)
Note: for testing samples with
antimicrobial activity, select filtration
units with low binding Durapore
membrane (item MMHVWP124 or item
MMHVWP224).
Note: Isopropyl myristate (IPM) is
not chemically compatible, therefore
samples containing IPM should not be
used.
• Open a box of filtration units and remove
the desired number of bags, each
containing a tray of eight filtration units
Note: you do not need a tool to open the
box of the filtration units. Grab one end
of the tape and pull it.
• Repeat the operation if more than one
box of filtration units is needed.
• Clean each bag using a wipe moistened
with one of the surface sanitizers listed in
the cleaning & maintenance section
Optional: if you need four filtration units
or less for your testing, open the bag at
the front of the safety cabinet, then pull
out only half of the tray, separate the tray
in two and place the “half-tray” in the
working area. Fold the bag to close it and
use the biggest part of the sticker situated
on the bag to secure its closure. The four
filtration units remaining in the bag can
be put aside for later usage. In this case
the bag can be opened by the sealed end,
which is achieved by pulling on each side of
the bag.

• Open a bag and remove the tray, then
place the tray near the pump
• Repeat the operation if more filtration
units are needed
Optional: to save space, trays can be
separated in two parts and stacked.

saving
Note: Four stickers with traceability
information and 2D barcodes are present
on each bag. It is possible to detach the
stickers and stick them into a log book.
