Bio-Rad PTC-240

This used Bio-Rad PTC-240 Tetrad thermal cycler is a multi-block instrument designed to run several independent PCR protocols at once, making it a valuable tool for labs juggling multiple assays or sample sets simultaneously. Featuring four individually controllable thermal blocks, the PTC-240 allows technicians to run different temperature profiles side by side in a single instrument, improving throughput without requiring several separate cyclers. Its robust Peltier-driven design carries forward the dependable cycling performance associated with the broader PTC series. Laboratories used the PTC-240 for applications ranging from routine PCR amplification to more complex protocol optimization work, where running parallel programs on the same instrument saved significant bench time. The ability to independently manage each block gave researchers flexibility to test different annealing temperatures, cycle numbers, or extension times concurrently, which was especially useful during method development and troubleshooting. Its solid construction has allowed many of these units to remain in reliable service long after their original installation. This pre-owned PTC-240 has been tested for proper multi-block cycling function and is offered as a cost-effective way to add flexible, parallel PCR throughput to a lab's existing equipment lineup. It is a good match for research groups that need to run several distinct protocols concurrently without investing in multiple standalone cyclers.
