4. Maintaining the Pipette
As with any precision instrument, pipettes have many mechanical and
electronic parts that are subject to wear and tear. By taking care of
your pipette and carrying out regular maintenance and adjustment,
its functionality and performance can be ensured. Cleaning is always
recommended after possible contamination or after dispensing corrosive or
aggressive chemicals.
To avoid pipette and sample contamination and to extend the pipette's
lifetime, Sartorius Safe-Cone Filters (available for pipettes >10 µl) or Sartorius
SafetySpace Filter Tips should be used.
Sartorius provides service, maintenance, and calibration services through its
global network of service centres. Please contact your nearest service centre
for assistance.
The warranty will be voided if the pipette is disassembled or assembled by an
unauthorized person.
NOTE:
Make sure the pipette has been decontaminated before you send it for
repair or calibration. Be sure to note any hazardous material that the pipette
has been exposed to. For more information
NOTE:
Turn off the pipette prior to cleaning.
NOTE: It is recommended that gloves are always worn when cleaning the
pipette.
4.1. Cleaning the Outer Surface of the Pipette (daily)
To clean and decontaminate the outer surface of the pipette, use a
disinfectant liquid or mild detergent , for example 70% ethanol, 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.
Always check the chemical compatibility between the pipette materials and
the disinfectant or decontaminant liquid.
Change the Safe-Cone Filter regularly with the tweezers provided with the
pipette.
Do not let liquids enter the inner parts of the pipette.
4.1.1. Cleaning the Lower Part of a Single Channel
Pipette (every three months)
If the pipette is in daily use, it is recommended to clean, decontaminate, and
grease it every three months.
NOTE: We recommend sending multichannel pipettes to your local Sartorius
service center for cleaning and greasing.
