Product Information

Technical Data



The Mastercycler® nexus PCR cycler provides you with flexibility in many forms. Conduct PCR runs with a range of standard vessel types, from 0.2 mL tubes to 96 well plates using a single 96-well aluminum block. So there is no need to buy additional blocks, and for even faster ramp rates, silver block variants can be used instead.

If you need higher throughput, simply connect up to two eco cyclers to a programmable nexus thermal cycler for additional capacity. The configuration can also include the nexus X2 eco units – providing up to 6 independently operating blocks. The Mastercycler nexus cycler can even email you when the PCR run is complete – what else do you need from a PCR cycler?

The flexlid® concept for effortless height adjustment

The flexlid enables the nexus to easily deal with all types of PCR consumables, from low volume wells all the way up to 0.5 mL PCR tubes, and of course all common PCR plates.  

Gradient with SteadySlope® technology

To ensure that heating and cooling ramp rates are exactly the same in both gradient and normal operation, the Mastercycler nexus gradient option features SteadySlope technology. This gives you identical temperature control characteristics in both optimization and routine experiments.

Certified quality

All Eppendorf cyclers follow these quality guidelines:
• Individual quality control certificates
• Calibration according to national and international standards, e.g. NIST (USA), DKD/PTB (Germany), UKAS/NPL (UK)
• UL/cUL listed

Concerned about your lab's carbon footprint or electricity bill?

Eppendorf's Mastercycler nexus is optimized for low power consumption – regardless of whether the cycler is running, idle, or in standby mode.

Suffering from noise in the lab?

With many different instruments in the lab, noise levels can easily become too high. The Mastercycler nexus is a whisper quiet PCR cycler. Low noise levels make working in your lab more pleasant and enjoyable – particularly when you’re thinking about how to achieve your next big breakthrough!

Improving ergonomics across the lab

Ergonomics goes far beyond just the ergonomically designed chair. At Eppendorf, we began optimizing our laboratory devices for ergonomics in the early 1970s.

In 2003, we launched the PhysioCare Concept®, focusing on ergonomic liquid handling devices, like our pipettes.

Since then we’ve broadened the Eppendorf PhysioCare concept to include many laboratory products, including PCR cyclers. Our aim is to offer a holistic solution for harmonizing the workflow in your laboratory with your health and wellbeing.

For the Eppendorf Mastercyler range, this means:

• Ergonomically designed lid closure
• Low noise level for convenient working conditions at the bench
• Small footprint to enable position in direct arm reach at your bench
• Standardized user-interface concept for intuitive handling of devices
• Guided software for easy handling
