7.1 Cleaning the Outer Surface of the Pipette (daily)
Your Tacta® pipette should be checked daily to ensure it is clean.
To clean and decontaminate the outer surface of the pipette, use a disinfectant liquid or mild detergent and a soft, lint-free cloth.
Gently clean the surface of the pipette with the moistened cloth and wipe it dry. Pay special attention to the tip cone.
Change the tip cone filter.
