Reusable aluminum blocks for keeping tubes organized while transferring heat or cold around samples and reagents. Choose dedicated 1.5/2.0 mL formats, mixed PCR-and-tube layouts or high-density PCR blocks.
The useful differences are tube diameter, number of positions and whether the run uses one tube format or several. Current blocks are rated for −80 to 100 °C unless the individual product page states otherwise.

Aluminum transfers heat efficiently and lets samples sit in defined positions instead of loose in an ice bucket or warm-water container. A pre-cooled or pre-warmed block can keep a batch organized while samples or reagents are handled on the bench.
These are general laboratory heating/cooling blocks, not instrument-specific dry-bath inserts unless an individual product page explicitly states compatibility with a particular instrument.
If the workflow is mainly 1.5/2.0 mL tubes, the 15- and 24-position blocks are the simplest options. Mixed-format blocks are useful when PCR tubes and larger tubes need to stay together through the same workflow.
For PCR-heavy work, the 96 + 10 and 384-position blocks reduce the need to split samples across several smaller blocks.
