Storage
After the system has been thoroughly cleaned, flushed, and tested,
it can be stored until needed for processing.
Storage pressures, feed flow rates, and volumes are identical to
those used for cleaning.
Refer to the appropriate user guide for storage solutions.
Storing the Filters in the System
1. Shut off the feed pump and clamp the lines to or from the
holder or shut the feed, retentate, and permeate valves to keep
the holder and filters full of storage solution.
2. Store the holder and filters at either ambient temperature or
2–8° C.
Storing the Filters without the System
The filters can be removed from the holder for storage.
1. Shut off the feed pump and drain the system.
2. Open the holder and remove the fully wetted filters.
3. Place the filters in a liquid tight container and fill the container
with excess storage solution to immerse the filter.
4. Seal the container and store at 2–8° C. Do not freeze.
Suitable storage containers include plastic freezer bags with zipper
seals, molded polyethylene or polypropylene freezer containers,
and plastic pails with locking and sealing lids.
