INTRODUCTION
Congratulations on purchasing your new
MICROMAN E®pipette. MICROMAN E is suitable
for many different applications, including
pipetting volatile, viscous, dense, or high surface
tension liquids. It is a quality product from Gilson,
which is fully compliant with ISO 8655 standards.
The six models available allow for precise and
accurate pipetting of viscous, dense, and volatile
liquids. They also enable contamination-free
pipetting, preventing vapor contamination and
cross-contamination. M25E, M50E, and M250E,
with thin and tall capillary pistons (CPs) are
especially suited for use with tall or narrow
vessels.
Enjoy the following features:
●MICROMAN E pipettes are equipped with a
positive displacement mechanism isolating
the aspirated liquid from the pipette body.
The positive displacement mechanism
prevents the sample-to-sample contamination
that can result from the aerosol effect.
●MICROMAN E uses disposable capillary
pistons. These are the only parts that contact
with the aspirated liquids, and replacement
thereof will provide absolute protection
against contamination caused by carryover
between samples or reagents. Simply replace
the capillary piston between assays; they are
ejected automatically and simultaneously,
thus avoiding any risk for the operator.
●MICROMAN E is equipped with a direct
reading volumeter that allows precise
adjustment of the required volume. At the
manufacturing stage, each MICROMAN E is
permanently adjusted to the corresponding
capillary piston. The capillary piston is
positioned automatically, and therefore
no further adjustment is requested when
replacing it.
●MICROMAN E requires no lubrication, due to
the nature and quality of the materials used in
its component parts.

PIPETTING
Setting the Volume
The volume of liquid to be aspirated is set using
the volumeter. The volumeter consists of three
number dials, which are read from top (most
significant digit) to bottom (least significant digit).
A marker is used to set exact or intermediate
volumes using the scale on the bottom dial.
The dials are colored either black or red to indicate
the position of the decimal point, according to the
model (see examples).
The volume is set by turning the thumbwheel
slowly to reach the required setting.
For small volume changes, directly and slowly
turn the thumbwhell.
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 pass the
setting.

For large volume changes, proceed as follows:
1. Slide and hold the
volume unlock
button to unlock the
volumeter.
2. When decreasing
the volume setting,
approach the
required setting,
by 1/3 of a turn.
When increasing the
volume setting, pass
the required setting
by 1/3 of a turn.
3. Release the unlock
button button.
Aspirating
1. Press the push button
to the first stop,
2. Immerse the capillary
2 mm into the liquid,
3. Slowly release the
push button to draw
up the liquid (top
position),
4. Wipe any liquid
from the outside of
the capillary, taking
care not to touch the
orifice.
Greater uniformity and precision of dispensing
are usually obtained by providing identical
contact surfaces for all aliquots. This is
achieved by pre-rinsing with the same liquid
that is being dispensed.
To pre-rinse, aspirate with the tip and then
dispense back into the original reservoir or to
waste.

MICROMAN E is automatically
adjusted when the capillary piston is
correctly fitted. Once the volume is set,
measurements will be accurate and
precise.
Dispensing
Place the end of the capillary against the inside
wall of the recipient vessel,
1. Press the push button slowly to the first stop,
2. Keeping the push button depressed, move
the capillary away from the sidewall,
Withdraw MICROMAN E from the vessel and
release the push button.
Ejecting the Capillary Piston
●Press the push button to the first stop, and
then press down harder to the second stop;
at this point the piston and capillary are
ejected simultaneously.

TROUBLESHOOTING
You may be able to identify and correct the
problem by referring to the following information.
If you cannot solve the problem, please contact
your local Gilson representative.
Leaks:
Replace the capillary piston.
No stroke:
The piston is not properly fitted into the clamp;
check that the piston is seated correctly (refer to
pages 8). Without any capillary piston, press the
push button to the first stop, and then press down
harder to the second stop.
Dicult to fit a capillary:
Clean the capillary holder with ethanol. Without
any capillary piston, press the push button to
the first stop, and then press down harder to the
second stop.
Inaccuracy:
Make sure the capillary is correctly mounted on
the capillary holder (refer to CHAPTER 2, FITTING
THE CAPILLARY PISTON, pages 8).
Imprecision:
Replace the capillary piston.
Dicult to set the volume:
This suggests internal damage to the pipette.
Contact your local Gilson representative.

CLEANING AND
DECONTAMINATION
MICROMAN E is designed so that parts normally
in contact with liquid contaminants are easy to
clean and decontaminate.
Cleaning
Clean the pipette with soap solution prior to
decontamination.
External
1. Wipe the entire pipette with a soft cloth or
lint-free tissue soaked with soap solution
to remove any stains. If the pipette is very
dirty, a brush with soft plastic bristles may
be used.
2. Wipe the entire pipette with a soft cloth or
lint-free tissue soaked with distilled water.
3. Leave the parts to dry by evaporation or
wipe them down with a clean soft cloth or
lint-free tissue.
Internal
Only the following components should be
immersed in a decontaminant solution: clamp
assembly, return spring, and capillary holder
(shaft).
1. Unscrew the capillary holder (shaft).
2. Remove the clamp assembly and return
spring from the shaft.
3. Set aside the body (handle) in a dry and
secure location.
Before returning any pipette,
ensure that it is completely
free of chemical, biological, or
radioactive contamination. Use
the safety bag provided by Gilson.
