INTRODUCTION
PIPETMAN G®is a fully adjustable air
displacement pipette and is used with disposable
tips. To answer the current needs of the loyal
users of our pipette, and still conform to Gilson
brand qualities, three improvements have been
added to our mechanical series:
●pipetting and purge forces dramatically
decreased*,
●large volumes, 5 mL and 10 mL very
comfortable,
●choose a plastic ejector or a stainless steel
ejector.
*Implementation of new features to improve dramatically
pipetting comfort has no impact on the legendary robustness,
accuracy and precision of PIPETMAN.
Eight single channel models cover a volume
range from 0.2 µL to 10 mL.
Parts Check List
Just take a moment to verify that the following
items are present:
●PIPETMAN G,
●User’s Guide,
●Safety bag,
●Certificate of conformity
(including barcode sticker).
Decreased pipetting forces are
due to the new designed piston
assembly including the use of a
very high quality of lubricant. The
use of other lubricant cancels
the warranty of this pipette. This
lubricant is available under the
reference: 5440011070. Please

Each pipette model (except P5000G and P10 mLG)
has two different ordering references to identify the
kind of tip ejector required. For a pipette with a
plastic tip ejector, the ordering reference is ended
by the letter P, for a pipette with a stainless steel tip
ejector, the ordering reference is ended by the letter
M. Ex: For a P10G model with the plastic tip ejector
the ordering reference is F144055P. For the same
pipette with a stainless steel tip ejector, the ordering
reference is F144055P.

PIPETTING
It is recommended to use PIPETMAN® DIAMOND
Tips with the PIPETMAN G for optimum
performance. These tips are made from pure
polypropylene. Plastic tips are for a single
application—they must not be cleaned for reuse.
Fit the Tips
To fit a new PIPETMAN DIAMOND Tip, push the tip
holder into the tip using a slight twisting motion to
ensure a firm, airtight seal.
For the P2G and P10G Models Equipped with
Stainless Steel Tip Ejector,
A dual-position adapter (plastic)
is required to fit DL10 tips
(long tips) or D10 tips (short
tips).
P2G and P10G models are
delivered with the adapter
in place, ready to use
DL10 tips. If D10 tips are
used, the adapter must be
repositioned in the shorter
slot as follows:
1. Pull the adapter down
from the metallic rod.
2. Turn the adapter through
180°C.
3. Refit the adapter so that
the end of the metallic
rod engages the shorter
slot of the adapter.

SETTING THE VOLUME
The volume of liquid to be
aspirated is set using the
volumeter. The dials are
colored either black or red to
indicate the position of the
decimal point, depending on
the model (see examples).
The volume is set by turning the thumbwheel or the
push button. The push button makes it easier and
quicker to set volumes, especially when wearing
gloves. The thumbwheel may be turned using only
one hand to slowly reach the required setting.
To obtain maximum accuracy when setting the
volume, proceed as follows:
●when decreasing
the volume setting,
slowly reach the
required setting,
making sure not to
overshoot the mark.
●when increasing the
volume setting, pass
the required value
by 1/3 of a turn and
then slowly decrease
to reach the volume,
making sure not to
overshoot the mark.

1. Place the end of the tip against the inside wall of
the recipient vessel (at an angle of 10° to 40°).
2. Press the push button slowly and smoothly
to the first stop.
3. Wait for at least a second, then press the
push button to the second stop to expel
any residual liquid from the tip. Keep the
push button pressed fully down and (while
removing the pipette) draw the tip along the
inside surface of the vessel.
4. Release the push button, smoothly. Eject the
tip by pressing firmly on the tip ejector button.
Figure 6
Pipetting Motion - Aspirate and Dispense
For the P2G and P10G Models Equipped with
Plastic Tip Ejector,
A tip ejector extension is supplied to fit
with D10 tips (short tips).
To fit a tip ejector extension:
1. Slide the extension over the tip
holder.
2. Push the extension firmly onto
the end of the tip ejector until it
clicks into place.
To remove a tip ejector extension:
1. Gently twist the extension.
2. Pull it away from the pipette.
Both dual-position adapter and tip ejector
extension are autoclavable .
Pre-rinse the Tips
Some liquids (e.g.,protein-containing solutions
and organic solvents) can leave a film of liquid
on the inside wall of the tip; pre-rinse the tip to
minimize any errors that may be related to this
phenomenon.
Pre-rinsing consists of aspirating the first volume
of liquid and then dispensing it back into the
same vessel (or to waste). Subsequent volumes
that you pipette will have levels of accuracy and
precision within specifications.
Aspirate
1. Press the push button to the first stop
(this corresponds to the set volume of
liquid).
2. Hold the pipette vertically and immerse the
tip in the liquid (see immersion depth table,
page 12). Release the push button slowly
and smoothly (to top position) to aspirate
the set volume of liquid. Wait one second
(time depends on model, see table); then
withdraw the pipette-tip from the liquid.
You may wipe any droplets away from the
outside of the tip using a medical wipe,
however if you do so take care to avoid
touching the tip’s orifice.

10. You may remove the tip ejector, see
CHAPTER 6 - MAINTENANCE to aspirate
from very narrow tubes.
11. After pipetting acids or other corrosive liquids
that emit vapors, remove the tip ejector, the tip
holder, rinse, dry and lubricate the piston, see
CHAPTER 6 - MAINTENANCE. For the model
P1000G, by using a specific tip holder equipped
with a filter, you can increase the lifetime of the
piston, see CHAPTER 4 - ACCESSORIES.
12. Do not pipette liquids having 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).
Guidelines for Good Pipetting
1. Make sure that you operate the push button
slowly and smoothly.
2. When aspirating, keep the tip at a constant
depth below the surface of the liquid (refer to
the table).
3. Change the tip before aspirating a different
liquid, sample, or reagent.
4. Change the tip if a droplet remains at the end of
the tip from the previous pipetting operation.
5. Each new tip should be pre-rinsed with the
liquid to be pipetted.
6. 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.
7. If you use the same tip with a higher volume,
pre-rinse the tip.
8. For volatile solvents you should saturate the
air-cushion of your pipette by aspirating and
dispensing the solvent repeatedly before
aspirating the sample.
9. When pipetting liquids with temperatures
different to the ambient temperature, pre-rinse
the tip several times before use.

Each pipette model (except P5000G and
P10mLG) has two different ordering references
to identify the kind of tip ejector required. For
a pipette with a plastic tip ejector, the ordering
reference is ended by the letter P, for a pipette
with a stainless steel tip ejector, the ordering
reference is ended by the letter M. Ex: For a P10G
model with the plastic tip ejector the ordering
reference is F144055P. For the same pipette with
a stainless steel tip ejector, the ordering reference
is F144055M.
