4. Safety Recommendations
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.
Risk of damage to the pipettor or errors
NOTE
in pipetting.
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 Instructions for
Use or transferred to a service point.
• Ambient operating temperature is +5°C to 45°C.
• Ambient storage conditions (in the original packaging
during transport and short storage) is -25°C to 55°C.
When working with the pipettor:
• Follow general work safety regulations regarding
hazards related to work in the laboratory.
• Take special care when pipetting aggressive
substances.
• Use appropriate protective attire (e.g., clothing,
goggles, and gloves).
• Avoid pointing the pipettor at yourself or others
during use.
• Only use parts and accessories recommended
by the manufacturer.

5. Specifications
The pipettor is a high quality instrument which offers
excellent accuracy and precision. The accuracy and
precision (repeatability) of the liquid volume depends on
the quality of pipet tips used. The values for accuracy and
precision shown in the table below were obtained using
manufacturer non-filter pipet tips. Those tips are recom-
mended for use to ensure compatibility, accuracy and
precision when pipetting.
