Autoclaving the 0.2 µm final filter
NOTE!
The lifetime of the 0.2 µm final filter can be prolonged by sterilizing it. Proceed as follows to
autoclave the sterile filter.
Step Action Figure
1 Rotate the used 0.2 µm final filter in a
clockwise direction to remove it.
2 Use an autoclave to sterilize the 0.2 µm final
filter in a steam autoclave at 121C° for 30
minutes. You can repeat the sterilization
process for the sterile filter up to 5 times.
When sterilization is completed, screw the 0.2
µm final filter back into the 1/4“ thread on the
sampling tap (see “Replacing the 0.2 µm final
filter” on page 61).
NOTE!
If you wish to remove purified water and the flow rate
is too low, this is an indication that the sterile filter is
clogged. In this case, read the description in Chapter
15 “Trouble shooting” on page 77, or replace the 0.2
µm final filter with a new one.
