Product Information

The Mastercycler® nexus X2 is Eppendorf's solution for busy PCR labs. Two totally independent protocols can be run on the two blocks, so two PCR users can independently start and end their PCR reactions whenever they want. One of the assays can even have up to 64 samples. With less than 40 dB[a] noise emission, the nexus PCR cycler is whisper quiet and also very energy efficient.

Technical Data



Run two independent protocols simultaneously on one PCR thermal cycler with the Eppendorf Mastercycler® nexus X2. The 32-well block is well suited for small assays, whereas larger assays can be run on the 64-well block, which is available with a gradient function.

Like every member of the Mastercycler nexus family, the Mastercycler nexus X2 can be combined with all other family members in a network of up to three units. In combination with Eppendorf’s PCR tubes, PCR strips or divisible plates, the Mastercycler nexus X2 will give you consistent, publication-ready results – every day!

The flexlid® concept for effortless height adjustment

The flexlid concept enables the nexus X2 PCR thermal cycler to deal with all types of consumables, from low volume all the way up to 0.5 mL PCR tubes. Of course, all common PCR plates fit – and if you ever need higher throughput, you can simply connect one or two Mastercycler nexus X2 eco units to your Mastercycler nexus.

Gradient with SteadySlope® technology

The Mastercycler pro’s gradient option features SteadySlope technology to ensure that heating and cooling ramp rates are identical in both gradient and normal operation. This gives you identical temperature control characteristics in both optimization and routine experiments. Programming the gradient with the Control Panel and the CycleManager pro is easy and intuitive, so that new users can get started quickly and safely.

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

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
