1.5Glossary
F
flexlid
The heated lid of the thermal cycler automatically adapts to the used tubes or plates. This always ensures
that a reliable pressure is applied to the thermoblock and that the tubes are sealed securely. Unlike
conventional heated lids, they do not need to be manually adjusted.
T
Thermal Sample Protection
When the heated lid is being heated, the thermoblock is actively maintained at a constant temperature. This
minimizes non-specific annealing and evaporation of the samples.
Triple circuit technology
The thermoblock is controlled by three independent control loops. This is necessary to produce
temperature gradients and leads to improved temperature homogeneity.

2.3Features
Triple Circuit Technology
The Triple Circuit Technology leads to a homogeneous temperature distribution and enables for
Mastercycler nexus gradient, Mastercycler nexus GSX1 and Mastercycler nexus GX2 a selective generation
of temperature gradients for PCR optimizations.
SteadySlope
The SteadySlope technology ensures that the heating and cooling rates of the thermoblock in gradient
operation are identical to those in normal operation. A reliable transfer of the optimization results to the
routine application is ensured.
flexlid
All variants of the Mastercycler nexus have a flexlid heated lid. It enables ergonomic operation with one
hand and automatically adjusts the contact pressure for all tubes and PCR plates.
Thermal Sample Protection
The Thermal Sample Protection technology maintains a constant thermoblock temperature of 20°C during
the warm-up phase of the heated lid. Thermal Sample Protection reduces the thermal load on your samples
and minimizes the probability of non-specific product formation during the PCR.
Self-test function
The master variants of the Mastercycler nexus have an integrated self-test function. The self-test function
provides a simple way of testing the correct function of the thermoblock without any further tools. A
separately available USB key is required for the self test function (see Accessories on p. 105).
Control
The eco variants of the Mastercycler nexus do not have a control panel. They are controlled via a connected
master variant of the Mastercycler nexus.
Standby function
All variants of the Mastercycler nexus can be switched to standby mode automatically or by pressing a
key.This reduces energy consumption and ensures that the device is ready for use at any time.

order to automatically cool the samples after the PCR.
Temp. mode Block temperature control mode
• fast:
Use this setting for Fast PCR, for low reaction volumes (< 20 µL) and for templates
with a low G/C content. With this setting you achieve the shortest program run
times.
• standard: Block temperature control mode for standard applications.
Use this setting for sample volumes between 20 µL and 50 µL or if the fast setting
only results in a weak amplification. The program run times are slightly longer
than with the fast setting.
• safe: Block temperature control mode for complex templates and large reaction
volumes.
Use this setting for sample volumes of 50 µL or more or to amplify templates with
a high G+C content. The program run times are slightly longer than with the
standard setting.

Place the tubes or strips into the center of the thermoblock and ensure that they are symmetrically
positioned. This is applicable for individual tubes, ube strips and segments of separable PCR plates.
Load the 96-well thermoblock with at least 5 tubes. If you have fewer reaction batches, also add empty
tubes so the thermoblock is loaded with at least 5 tubes.
Load the 64+32-well thermoblock with at least 2 tubes. If you have fewer reaction batches, also add
empty tubes so the thermoblock is loaded with at least 2 tubes.
Very soft PCR tubes may become deformed at high temperatures. To prevent deformations:
• Increase the number of empty sample tubes in the thermoblock.
• Reduce the temperature of the heated lid (see p. 52).
• Use original Eppendorf PCR consumables. Eppendorf PCR consumables are optimally
suited for the device.
