We recommend leveraging the included Aluminum Block when running the Temperature Module. To check if your labware will fit on the aluminum block, consult the dimensions in the Temperature Module White Paper. For additional information on compatible labware, please reference our Support team’s labware compatibility article.

Please reference our Temperature Module White Paper for details on the module’s accuracy, uniformity, and time-to-temperature specifications, as well as technical drawings.

It is possible to use multiple modules of the same type on the OT-2. This is true for our Temperature Module, Magnetic Module, and Heater-Shaker Module. For a walkthrough on setting this up for your OT-2 and considerations when using multiple modules, please reference this guide.
