1 - INTRODUCTION
The DISCOVERY Comfort series of adjustable multichannel
pipettes have been designed for the filling of laboratory
microplates. The pipettes enable precise and simultaneous
delivery of 8 or 12 preset-volume doses of liquid.
DISCOVERY Comfort pipettes are produced in four
ranges of volumes: 1-10 μl, 5-50 μl, 20-200 μl, 50-300 μl.
DISCOVERY Comfort pipettes are made 3 colour
versions, which make the identification of the specific
volumes easier.
The DISCOVERY Comfort pipettes are equipped with a
digital counter which shows the pipetting volume. The set
volume is visible in the window on the handle. The setting
of the volume is done by turning of the pipetting push-
button knob (Fig. 1A2) or by turning the adjustment knob
(Fig.1B). The pipette design allows the user to lock the
volume setting by pushing the locking ring upwards
(Fig.1J). The position of the ring is indicated by the sym-
bols located on the handle. The range of the volume of
the aspired liquid is shown on the pipetting pushbutton
(Fig. 1A1).
DISCOVERY Comfort pipettes should be used with
polypropylene disposable tips, to ensure safety and accu-
racy (Fig. 1H). The shafts without O-rings ensure the
compatibility of the pipettes with a broad assortment of
tips, and the special ejector shape reduces the force
required for their ejection. In order to protect the user
against inadvertent contact with used tips, the pipettes
are equipped with tip ejectors (Fig. 1F).
The pipette construction allows to rotate the multichannel
module and to eject the tips through 360°, therefore, the
1
most convenient position may be selected to fill the
microplates. It is recommended to turn the module clock-
wise, (Fig. 2).
The specifications for accuracy and precision given in
the following table are obtained using HTL tips. These
figures are only guaranteed when HTL tips are used.

The specifications for the volumetric performance
are derived from extensive gravimetric tests according to
EN ISO 8655 standard.
Condition of measurments: distilled water at temperature
20±1°C
The pipette design enables the user to perform the recalibra-
tion process according to the rules presented in section 5.
