the recommendations below will ensure maximum
performance from your PiPetman Fixed.
• Make sure to operate the
PiPetman Fixed slowly
and smoothly.
• When aspirating, keep the tip at a constant depth
below the surface of the liquid.
• The
PiPetman Fixed should be held in the vertical
position.
• Change the tip before aspirating a different liquid,
sample or reagent.
• Change the tip if a droplet remains on the end of
the tip from the previous pipetting operation.
• Each new tip should be pre-rinsed with the liquid
to be pipetted.
• Liquid should never enter the
PiPetman Fixed
tip-holder. to prevent this:
- Press and release the push-button slowly and
smoothly.
- never turn the pipette upside down.
- never lay the pipette on its side when there is
liquid in the tip. Use a dedicated stand or hang-

.
• Never grease pistons or seals.
The pipette can be used b 4 °C and +
40 °C but the specifications may vary according
the temperature (see Chapter 2 for controlled
conditions of use).
• When pipetting liquids with temperatures different
from the ambient temperature, it is recommended
to pre-rinse the tip several times before use.
• Do not pipette liquids with temperatures above
70 °C or below 4 °C.
• After pipetting acids or corrosive liquids which
emit vapors, it is recommended to disassemble
the tip-holder and to rinse the piston, the O-ring
and seal with distilled water.
