Maintenance; Cleaning And Decontaminating The Pipette; In-House Maintenance - Sartorius ePET User Manual

11. Maintenance

To maintain the best results with your ePET®
pipette, the cleanliness of every unit should be
checked daily. Particular attention should be paid
to the tip cone(s).
ePET® pipettes have been designed for easy
in-house service. However, Sartorius also provides
a complete repair and recalibration service,
which includes a service report and performance
certificate(s). Please return your pipette to your
local representative for repair or performance
test/recalibration. Before returning it, please
make sure that it is free of any contamination.
Please advise our Service Representative of any
hazardous materials, which may have been used
with your pipette.
NOTE: Check the performance of your ePET®
pipette regularly e.g. every 3 months and always
after in-house service or maintenance.
11.1. Cleaning and
Decontaminating the Pipette
Your ePET® pipette should be checked every
day for cleanliness. To clean and decontaminate
the outer surface of your pipette use ethanol
(70%), isopropanol (60%) or a mild detergent as
a cleaning agent.
Gently clean the surface of the pipette with a
moistened cloth and then wipe dry. Pay special
attention to the tip cone. Change the Safe-Cone
Filter if needed (Chapter 6.6.)

11.2. In-house Maintenance

1. Remove the tip ejector collar: Gently twist
the tip ejector collar anti-clockwise and slide
it off.
2. Using 70% ethanol, 60% isopropanol, or a
mild detergent, and a soft lint-free cloth,
disinfect the tip ejector collar and the tip
cone.
3. Unscrew, anti-clockwise, the tip cone and
remove it, exposing the piston. In the event
the piston sticks to the tip cone, remove the
piston with a pair of tweezers.
