PIPETTING

PIPETMAN® CLASSIC
●
Each new tip should be pre-rinsed with the liquid
to be pipetted.
● Liquid should never enter the 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.
●
If you use the same tip with a larger volume,
pre-rinse the tip.
● For volatile solvents, saturate the air cushion
in your pipette by aspirating and dispensing
the solvent repeatedly before aspirating the
sample.
● When the temperature of the liquid is
different from the ambient temperature,
pre-rinse the tip several times before use.
●
You may remove the tip ejector (refer to
Changing the Tip Ejector on page 15) to
aspirate from very narrow tubes.
●
After pipetting acids or other corrosive
liquids that emit vapors, remove the tip
holder; then rinse the piston, O-ring, and seal
with distilled water. For the P1000 model,
use a specific tip holder equipped with a
filter to increase the lifetime of the piston
(refer to ACCESSORIES on page 11).
●
Do not pipette liquids with temperatures
above 70°C or below 4°C. The pipette
can be used between 4°C and 40°C, but
the specifications may vary according to
the temperature (refer to the ISO 8655-2
standard for conditions of use).
