Dosing lift
The dosing lift is fixed to the back of the weighing chamber. It
contains the mechanism that moves the dosing module up
and down during the dosing procedure and is controlled
through the terminal.
Top panel
The Q3 dosing module includes a top panel especially
designed to minimize the influence of the environment on the
dosing process. An opening in the top panel allows the tip of
the dosing head to penetrate the weighing chamber while
dosing. The top panel is attached to the bottom part of the
dosing module, moving up and down together with it.
While the dosing module is at its uppermost position, other
weighing methods and accessories can be used normally.
Dosing head holder
The dosing head holder consists of four pins that hold the
dosing head in place. Once installed, the dosing head is
secured and can only be released by pressing one of the
release buttons on either side of the holder, while the dosing
module is at its uppermost position. The holder includes an
RFID reader to identify the attached dosing head.
Optical sensor for HeightDetect
The dosing module is equipped with an optical sensor to
detect the height of the sample vessel opening (Height-
Detect). This allows automatic vertical positioning of the
dosing module for fast and safe dosing.
