1  INTRODUCTION
Congratulations on acquiring your new MICROMAN® pi-
pette. MICROMAN is suitable for many dierent types of
application, including pipetting volatile, viscous, dense,
or high surface tension liquids. It is a quality product
from Gilson, which is fully ISO8655 compliant, CE labeled
(conforms to the EC directive on in vitro diagnostic
medical devices).
The six models permit precise and accurate pipetting
of viscous, dense and vaporous liquids. They also
allow contamination free pipetting, avoiding vapor
contamination and cross-contamination. M25, M50 and
M250, with thin and long CPs are especially suited for use
with long or narrow vessels. M10 and M100 autoclavable
models are especially suited for 100 % contamination
free pipetting.
Enjoy the following features:
- MICROMAN pipettes are equipped with a positive
displacement mechanism that isolates the aspirated
liquid from the body of the pipette. The positive dis-
placement mechanism prevents the sample-to-sample
contamination that can result from the aerosol eect.
- MICROMAN uses disposable capillaries and pistons.
Changing these parts, which must be the only ones
to make contact with the aspirated liquids, can pro-
vide absolute protection against the contamination
caused by carry-over from one sample or reagent to
another. You simply have to change the capillary and
piston between each assay; they are automatically and
simultaneously ejected, thus avoiding any risk to the
operator.
- MICROMAN is equipped with a direct reading volu-
meter that allows precise and continuous adjustment
of the required volume. MICROMAN is permanently
calibrated at the manufacturing stage, the capillary
and piston are positioned automatically, therefore it
requires no further calibration.

4
- MICROMAN requires no lubrication or maintenance,
because of the nature and quality of the materials
used in its construction.

5  USING MICROMAN
Three simple steps are necessary:
1) Mount the capillary-piston.
2) Set the volume.
3) Aspirate and Dispense.
MICROMAN is automatically calibrated, by correctly fitting a
capillary-piston. After setting the volume, the volume measured
will be accurate and precise.

6  FITTING THE CAPILLARY AND PISTON
Verify that the model of capillary-
piston (CP) corresponds to the
MICROMAN you are preparing for use:
CP25, CP50 and CP250 Bulk
Capillaries and pistons are delivered in
two separate boxes. To t a capillary-
piston, follow this procedure:
1) Take care not to damage the sealing tip 1 when you
handle the piston 3.
2) Press the push-button to the second stop to open
the clamp 5.

ered already assembled. To t a cap-
illary-piston, follow this procedure:
1) Press the push-button on the
MICROMAN past the rst stop
position to the second stop po-
sition. The piston clamp should
now be open and protruding
from the capillary-holder.
2) Slide the MICROMAN piston
clamp inside the top of the capil-
lary tube until the piston clamp is
halfway down the piston mount-
ing stem.
3) Slowly release the push-button,
while pushing the body of the
MICROMAN into the capillary-
piston until it is rmly seated on
the MICROMAN.
4) Continue releasing the push-
button to ensure that the piston
is secured by the piston clamp.

7 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 signicant digit) to
bottom (least signicant 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).
Model Color of volumeter numbers
Black Red
M10, M25, M50 µL 0.1 µL
M100, M250 µL none
M1000 0.1 and 0.01 mL mL
The volume is set by turning the thumbwheel slowly to
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 over-
shoot the mark.
- when increasing the volume
setting, pass the required value
by 1/3 of a turn and then slowly
decrease the volume to reach
the required setting, making
sure not to overshoot the mark.

8  PIPETTING
Aspirating
- press the push-button to the
rst stop (1),
- immerse the capillary 2 mm
into the liquid,
- slowly, release the push-
button to draw up the
liquid (top position),
- wipe any liquid from the out-
side of the capillary, taking
care not to touch the orice.
Dispensing
- place the end of the capillary against the inside wall
of the recipient vessel,
- press the push-button slowly to the rst stop,
- keeping the push-button depressed, move the capillary
away from the side wall,
- withdraw MICROMAN from the vessel and release the
push-button.
