Replacing the Filter
Gently push nosepiece up and turn counter-clockwise until it is
separated from the pipette controller. Remove the filter from the
silicone pipette holder. Dispose of the filter and replace with
a fresh one.
The filter should be replaced every three months or when the
filter is contaminated by liquid or the suction capacity is slowed.
Note: Only use Cole-Parmer replacement filters to guarantee
a proper seal
CAUTION: Never operate the pipette controller without a filter.
Cleaning
This pipette controller can be cleaned with most common laboratory
disinfectants including isopropanol. Never use aggressive organic solvents.
The nosepiece can be autoclaved at 121°C, with the exception of the filter.
Follow the procedure under “Replacing the Filter” to remove the filter prior to
sterilization. No other portions of the controller are autoclavable.
