BioRad Tetrad 2 Thermal Cycler

  • Holds four 96- or 384-well alpha blocks
  • Heated bonnet lids
  • 90 day warranty

There are several reasons that the BioRad Tetrad 2 is one of the most requested thermal cyclers we sell. First, the BioRad Tetrad 2 Thermal Cycler allows users to run synchronous or independent reactions on four separate blocks while still maintaining a relatively small footprint, so it’s a great option for labs with high-throughput PCR application needs. Second, the BioRad Tetrad 2 has a control pad that is intuitive and very similar to those of the smaller PTC-100 and PTC-200 models. Third, the swappable block design allows users to switch from 96-well to 384-well blocks easily. (Please call or email regarding availability of each block style.) The BioRad Tetrad 2 also features advanced programming interface and increased file management tools, and is ideal for running multiple protocols and accommodating multiple users.  

Optional manufacturer's preventative maintenance program is available for this model. Please call or email for details. 

All of the equipment we sell is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
