General description

The Eppendorf Mastercycler X50 Thermocycler combines speed, flexibility and PCR optimization for research PCR applications and standardization for routine PCR applications such as food testing. A highly intuitive touch screen puts all these benefits at your fingertips.

Speed and enhanced PCR optimization functions, like the 2D-Gradient, make the Eppendorf Mastercycler X50 Thermocycler the ideal PCR cycler for advanced research in molecular biology. The excellent block temperature regulation gives rise to the next stage of PCR reproducibility, whereas the adaptable user management and profound documentation capabilities give peace of mind to laboratories working to specific or strict standards.

A highly intuitive touch display, low noise levels, low power consumption and the versatile flexlid concept combine to make a powerful PCR cycler. Up to 10 PCR cyclers can be combined – ideal for high throughput applications or labs with a high number of users running different assays. Should you feel you need more flexibility or throughput, up to 50 PCR cyclers can be combined in a computer-controlled network.
