A Better Than Gradient Approach to Thermal Cycling

The Veriti® 96-well Thermal Cycler features innovative VeriFlex Blocks for enhanced PCR functionality. Six separate peltier blocks provide maximal versatility and flexibility and offer two key benefits:

1. PCR Optimization: each block can be set with a specific temperature which is ideal for precise control over PCR optimization.
2. Run More Experiments: the six peltier blocks can also be used to run up to six different annealing temperatures in the same run. With this enhanced functionality,the Veriti 96-well Thermal Cycler with VeriFlex Blocks is the ideal thermal cycler for any lab.

VeriFlex™ Blocks on the Veriti® Thermal Cycler provide a better than gradient approach to PCR optimization. With six separate peltier blocks, you have precise control over the temperature that is set for the PCR optimization process.

• Use the on-board Tm calculator to approximate the optimal annealing temperature.
• Run up to six separate temperatures in the same plate to determine the optimal annealing temperature.
• VeriFlex Blocks maintain their thermal characteristics between optimizing and isothermal conditions—eliminating the need for further optimization steps.

VeriFlex Blocks: More than just for PCR optimization
VeriFlex Blocks have an additional benefit over gradient thermal cyclers. Since the peltier blocks are separate, it is possible to run up to six different temperatures in the same protocol step (Figure 1).

• Run up to six different annealing temperatures for cycle sequencing or endpoint PCR.
• Incubate samples at six different temperatures simultaneously.
