1 - INTRODUCTION

The DISCOVERY Comfort series of adjustable multichannel
pi pettes have been designed for the filling of la bo ratory
micro plates. The pipettes enable preci se and simultaneous
delivery of 8 or 12 preset-volume doses of liquid.
DISCOVERY Comfort pipettes are pro du ced in four
ranges of volu mes: 0.5-10 μl, 5-50 μl, 20-200 μl, 50-300 μl.
The DISCOVERY Comfort pipettes are equipped with a
digital co un ter 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 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 symbols 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
poly propylene disposable tips, to ensure safety and accu-
racy (Fig. 1H). The shafts without O-rings ensure the
compatibility of the pipettes with a wide range of tips,
and the special ejector shape reduces the force required
for their ejection. In order to protect the user from con-
tact with contaminated 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 measurements: distilled water at tem perature
20±1°C
The pipette design enables the user to perform the recalibra-
tion process according to the rules presented in section 5.
