Part numbers are 6190-164 (pack of 100) and 6190-165
(pack of 1000).
Operation
There are two ways of setting volume on Pipetman pipettes: with
the volume adjustment knob, or by turning the plunger button.
Both give exactly the same results.
Volume Setting using Plunger Button
1a.
Hold Pipetman in one hand. With thumb and forefinger, turn
the plunger button counterclockwise until the volume indica-
tor is
1
⁄
3
revolution above the desired setting, then turn slowly
clockwise until the desired volume shows on the indicator.
Volume Setting using Volume Adjustment Knob
1b.
Hold Pipetman in one hand. With the other hand, turn the vol-
ume adjustment knob counterclockwise so the volume indi-
cator is
1
⁄
3
revolution above the desired setting, then turn
slowly clockwise until the indicator shows the desired vol-
ume.
2.
ALWAYS dial down to the desired volume. This prevents
mechanical backlash from affecting accuracy. If you pass the
desired setting, turn the dial
1
⁄
3
revolution higher than desired
and reset the volume. The friction ring prevents unintentional
volume changes.
3.
Attach a new disposable tip to the pipette shaft. Press only
enough to make a positive airtight seal.
4.
Press the plunger to the
FIRST STOP
. This part of the stroke is the
volume displayed on the indicator.
5.
Holding Pipetman vertically, immerse the tip into the sample
to the proper depth; see page 5.
6.
Allow the pushbutton to return slowly to the
UP
position. Never
let it snap up!
7.
Pause briefly to ensure that the full volume of sample is
drawn into the tip.
8.
Withdraw the tip from the sample liquid. If any liquid remains
on the outside of the tip, wipe it carefully with a lint-free tissue,
avoiding the tip orifice.
9.
To dispense sample, touch the tip end against the side wall of
the receiving vessel and depress the plunger slowly to the first
stop.
Wait: 1 second* (P-2, P-10, P-20, P-100, P-200)
1-2 seconds* (P-1000)
2-3 seconds* (P-5000, P-10ML)
* Longer for viscous solutions.
Then press the plunger to the
SECOND STOP
(bottom of stroke),
expelling any residual liquid in the tip.
