Introduction
PIPETMAN® L is an air displacement pipette that uses
disposable tips.
Eight variable volume, single channel models cover a volume
range from 0.2 µL to 10 mL.
Fifteen fixed volume, single channel models cover a volume
range from 1 µL to 5000 µL.
Fourteen variable volume, multichannel models cover a
volume range from 0.5 L to 1200 L, including four V-ring
(VR) models, covering a volume range from 20 L to 300 L.
PIPETMAN L V-ring (VR) multichannel models are equipped
with V-rings at the bottom of the tip holders. They create an
airtight seal between the tip and pipette making proper fit
for most tip brands and low-force attachment with just one
gentle push.

(GLP) Compliance
The serial number is engraved on the
body of the pipette. It provides
unique identification of your pipette
and the date of manufacture.
For more details, refer to PIPETMAN L
User’s Guide LT801575 available on
gilson.com.
The barcode on the box and the
Certificate of Conformity provides
traceability for your pipette.

Lock System
For additional safety, the volume selected is lockable.
1. Unlock the thumbwheel
by pushing it up with
your thumb.
2. Set the volume
by turning the
thumbwheel.
The thumbwheel can be
turned using one hand
to slowly reach the
required setting.
3. Lock the newly set
volume by pushing
down on the
thumbwheel.
To obtain maximum accuracy when setting the volume:
●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.
User Adjustments (Fixed Volume Models Only)
PIPETMAN L fixed volume models are factory calibrated using
distilled water and very high precision balances. The nominal
volume may be adjusted slightly to compensate for liquids of
different density or viscosity.
To accommodate for density or viscosity, an adjustment of one
full turn of the adjustment key in either direction equals:
± 0.05 L (F1L to F2L)
± 0.2 L (F5L to F10L)
± 0.5 L (F20L to F25L)
± 2.0 L (F50L to F100L)
± 5.1 L (F200L to F250L)
± 20 L (F300L to F1000L)
± 102 L (F5000L)
The cover is graduated in
tenths of the key revolution
(letters A, B,..., J) and is read
from left to right. Each small
graduation mark represents
0.25 of the distance between each letter.
To adjust the nominal volume setting
to compensate for a specific density or
viscosity, engage the two hooks of the
spanner tool inside the two small holes on
the top of the body, and then turn the key
slowly:
●Clockwise to decrease the volume;
making sure not to overshoot the
mark.
●Counterclockwise to increase the
volume; pass the required value by
1/4 turn, and then slowly decrease
the volume to reach the required
setting.

V-Ring Multichannel Models
V-ring (VR) multichannel models complete the PIPETMAN L range
of multichannel pipettes with four models of 8- and 12-channel
pipettes covering a volume range from 20 L to 300 L.
PIPETMAN L multichannel V-ring models
have a leak-free tip holder design.
Each VR multichannel model has V-rings at
the bottom of the tip holders that create an
airtight seal between the tip and pipette to
get a proper fit for most tip brands and low-
force attachment with just one gentle push.

Fitting the Tip Ejector Adapter and the Tip
Ejector Extension
Single Channel Models
For P2L and P10L pipettes
equipped with a stainless steel tip
ejector, a dual-position adapter is
required to fit and eject DL10 tips
(long collar tips) and D10 tips (short
collar tips).
To fit the adapter for short and
long collar tips (refer to Figure 11):
1. Pull the adapter down
from the stainless steel
tip ejector.
2. Turn the adapter 180°.
3. Refit the adapter so that the end of the stainless steel tip
ejector engages the shorter or longer slot of the adapter.
For the F1L, F2L, F5L, F10L, P2L, and P10L equipped with a
plastic tip ejector, a tip ejector extension is supplied to fit with
D10 tips (short collar tips). Refer to Figure 11.
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 adapter.
2. Pull it away from the pipette.

Depending on the tip used, either D10 or DL10, you may have to
fit the ejector adapter. Long collar tips can be inserted without it.
1. Remove the tip ejector: keep both ejector locks depressed
1, and then pull the tip ejector down 2.
2. Fit the ejector adapter 3and click it to the tip ejector.
3. Gently re-insert the tip ejector vertically into the rails of
the ejector support 4.

Dispense
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 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.
Eject the Tips
Before you start to pipette, you can adjust the tip ejector button
according to your preferences.
1. Position the tip ejector button by rotating the tip ejector
button to the most comfortable position: left, right, or middle.
2. Activate the tip ejector. You can either push the tip ejector
button with the tip of the thumb as usual, or with the base of
your thumb for more comfort.
Pre-Wet the Tips
Pre-wetting the tips before pipetting helps prepare the tips for
the best pipetting performance. Ideally, the pre-wet includes
both immersing the tip in the liquid and performing one pipetting
step. Pre-wetting the tips helps ensure that volumes that you
pipette will achieve 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 below).
3. Release the push button slowly and smoothly to top
position to aspirate the set volume of liquid.
4. Wait one second (time depends on model, for more
details, please refer to PIPETMAN L User’s Guide
LT801575),and 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.
