Filters
The 5,000 and 10,000 μL pipettors include a replaceable
filter, fitted at the bottom of the shaft which prevents
aspirated liquid from entering the shaft and contami-
nating the inner surface and plunger. Use of the filter is
particularly important when aspirating and dispensing
large volumes of liquid. The filter should be replaced if it
becomes wet.

Long-term use of the pipettor relies on correct method
of use. Please read and follow the instructions for use
carefully.
Symbols used:
danger, risk of injury.

NOTE:
•
The pipettor is designed for the transfer of liquids only
using the tip. do not aspirate liquids without the tip
attached. The aspirated liquid should not enter the
pipettor, as it may cause damage.
•
Single-use tips reduce the risk of contamination of
samples.
•
Keep the pipettor clean, avoiding the use of abrasive
or corrosive cleaning agents (e.g., acetone).
•
Keep the pipettor upright when there is liquid in the
tip.
•
Only using the pipettor in accordance with the manu-
facturer’s instructions ensures the correct pipettor
parameters are maintained.
•
after replacing the plunger or the shaft, the pipettor
should be calibrated.
•
in the case of incorrect operation, the device should
be cleaned in accordance with the instruction Manual
or transferred to a service point.
