NOTICE!  Aggressive  substances  may  damage  components, 
consumables and accessories.

Check the chemical resistance before using organic solvents or
aggressive chemicals.

Only use liquids whose vapors do not a ack the materials used.

PIPETTE OPERATION

5.1   PIPETTING GUIDELINES

Check the  p cone to make sure it is clean.

While  using  the  pipe e  make  sure  that  opera ng  plunger  is
handled slowly and smoothly.

Ensure that the  p is firmly a ached on the  p cone. Please
check for foreign par cles and remove if any, around the  p
cone.

Make sure that the temperature of  p, pipe e and liquid are at
equilibrium.

While aspira ng, hold the pipe e in upright posi on and keep
the  ps at a constant depth below the surface of the liquid.

Pre-rinse  the  pipe e  p  before  aspira ng  the  sample  by
filling  and  emptying  the  pipe e  p  five  (5)  mes.  This  is
important when dispensing samples that have a viscosity and
density different from water and for vola le solvents.

Do  not  pre-rinse  the  p  when  pipe ng  samples  with
temperatures  different  from  the  current  ambient
temperature.  Be  sure  to  change  the  pipe e  p  a er  each
pipe ng.

For the vola le solvents you should saturate the air-cushion of
your  pipe e  by  aspira ng  and  dispensing  the  solvent
repeatedly before aspira ng the sample.

When  pipe ng  liquids  with  temperature  different  to  the
ambient temperature, pre-rinse  ps  p several  mes before
use.
