nOte: The accuracy of titration measurements
is affected by your technique. Be careful when
removing the cap of the cell extender to add
reagents. Flicking the cap or popping it off can
cause solution to spill out of the cell extender.
Always use a new pipette tip when changing
solutions to avoid contamination.
1. Pipette Instructions
always use a clean tip when changing
solutions! To install a tip, press the wide end of
the tip on the end of the pipette until it is secure.
To remove a tip, simply pull it off the end of the
pipette.

unscrew the shaft bottom from the pipette.
The pipette has 3 positions: REST, FIRST STOP, and SECOND STOP.
Practice pushing in and letting up on the pipette to feel the different
positions.
a. To DRAW a
sample: grasp the pipette by the shaft
with your hand. Rest your thumb on top
of the plunger button. Use your thumb
to depress the top of the pipette to the

sample until only the tip is submerged,
about 2-3mm/ 1/8". Slowly release the
top and let it return to the REST position
being careful to keep the tip submerged.
b. To DISPENSE
a sample: With the pipette in the REST
position, place the tip end over the
Do not allow the pipette tip to touch
the cell wall or the sample.
