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
color modules from all absorption spectra of the standard fluorescent dyes, from the
blue through the red excitation range.

The qTOWER³ 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 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.
