Instruction Manual – 15
• Set the locking ring to the lower (unlocked) position
prior to sterilization.
• Sterilize the pipettes using an autoclave with an initial
vacuum and drying cycle.
• After sterilization, the pipette should be dried and
cooled to room temperature.
Precision and accuracy should not alter if the pipetting
processes including autoclaving are carried out as
described in this manual. If a change in accuracy occurs,
it is recommended to:
• Check the calibration of the pipette after the first,
third, and fifth autoclaving cycles and then after every
10 autoclaving cycles.
Ultra Violet (UV) Sterilization
The EPRO® Sailor™ pipettes are UV resistant. The distance
from the radiation source to the exposed element of the
pipette should be at least 50 cm. Prolonged or intense UV
exposure can cause discoloration of pipette parts but does
not affect its performance.
11. Troubleshooting
If a problem is encountered during pipette operation, use
the following table to identify and eliminate the fault
following the instructions provided. Replacement of parts
should be required only occasionally and should not be
required with normal pipette use.
Problem
Cause
Solution
Droplets of
liquid remain
in the pipette
tip.
The pipette tip is emptied
too fast.
Decrease the speed
of pressing the pipette
pushbutton.
The pipette tip wettability
has increased due to
extensive use.
Replace the tip with
a new one.
Droplets
of air appear
in the liquid
aspirated
into the
pipette tip.
The pipette tip immersion
depth is too shallow.
Immerse the tip
to the recommended
depth according to the
instructions.
The pipette tip is
incorrectly pressed onto
the pipette shaft.
Press the pipette
tip firmly onto the
pipette.
The tip is damaged or
worn out due to extensive
use.
Replace the tip with
a new one.
