Fig. 1 Layout of the qTOWER³ touch
3.1 Fluorescence spectrometer
An 8-channel Epi fluorescence photometer with fiber -multiplexer and mechanical
scanning device is used as detection system.
Light for exciting the dyes is emitted by four long-life LEDs in blue, green, white and
red. The light is passed through optic fibers to collimator lenses, bundled and then
transferred to the excitation filter of the color modules fitted to a rotating filter wheel.
The light is deflected via a beam divider and passed through additional optic fibers to a
lens array in a shuttle system scanning the sample block in columns. The light excites
the fluorescence dyes in the reaction mix. The fluorescence dyes then emit a light of
longer wavelength that is bundled through the lenses in the shuttle system and passed
via the optic fibers back to the color modules. In the color modules the light passes the
beam divider followed by two emission filters and is then transferred to the photomul-
tiplier (CPM) for detection.
The filter wheel of the photometer can be populated freely with a choice of color filter
modules. In addition, color filter modules can be retrofitted at any time, extending the
application spectrum of the device. A total of 12 color filter modules are available. This
also includes filter modules especially optimized for FRET applications. You can chose

16
color modules from all absorption spectra of the standard fluorescent dyes, from the
blue through the red excitation range.
Fig. 2 Schematic structure of the Epi fluorescence photometer
3.2 PCR thermocycler
The qTOWER³ touch is equipped with a thermal block with 96 wells. To guarantee the
best possible performance and heat exchange capability, the thermal block is made
from gold-plated silver. This achieves a high temperature homogeneity and uniformity
in combination with heating rates of up to 8 °C/s and cooling rates of up to 6 °C/s.
The qTOWER³ G touch also features a 96 well thermal block but is additionally
equipped with a gradient function. The maximum temperature span of the gradient is
40 °C with 12 columns. This means that the device is particularly well prepared for
establishing new primary pairs.
The qTOWER³ touch is not limited to specific detection reagents or the plastic products
of a specific manufacturer. Optical plastic products in the formats 0.2 ml tubes, 8 well
strips with optical lids or 96 well micro titer plates can be used.
To avoid condensation or potential sample loss, the qTOWER³ touch is equipped with a
motorized heated lid. This can be adjusted up to 110 °C and guarantees an optimum
contact pressure on the sample vessels during the entire real-time PCR run process
irrespective of the consumables used.
