The Mastercycler nexus GX2e gives you the ability to run two totally independent protocols at the same time. Smaller assays fit nicely on the 32-well-block - larger assays can exceed 48 samples and run on the 64-well-block. The larger block is available with a gradient function. As every member of the Mastercycler nexus family, the Mastercycler nexus GX2e can be combined with all other family members in a network of up to 3 units. In combination with Eppendorfs PCR Tubes, PCR Strips or divisible plates, the Mastercycler nexus X2 will give you consistent and publishable results - every day!
