ActionStep
Replace the pH electrode with the pH CIP cap (pH plug). The electrode should
be stored in 3 M potassium chloride. Place the pH electrode in the pH elec-
trode holder, with the end submerged in storage solution.
Note:
Do not store the pH electrode in water only.
2
Seal off ÄKTAprocess to prevent contamination caused by the surrounding
environment.
3
Fill ÄKTAprocess with the storage solution of choice. The air trap should be
filled to approximately one quarter of the maximum operating volume to
prevent microbial growth.
4
Store columns and absorbents according to the instructions that are appli-
cable in each case.
5
Long term storage
The table below describes the procedure for long term storage. This procedure is appli-
cable for storage durations of longer than one month.
ActionStep
Perform the actions described for Short term storage, above.1
Place ÄKTAprocess in a dust free environment with well-controlled climate.
The temperature should be stable and in the range 4ºC to 25ºC.
The air humidity and air temperature differences should be kept as low as
possible to prevent condensation and corrosion.
2
For long term storage periods, store any unused TC-rubber gaskets in a cool
dark place. This prevents them from aging and drying out.
3
To prevent microbial growth, the storage solution shall be replaced regularly
if ÄKTAprocess is stored for long periods of time.
