Corning CoolRack® Conical-Bottom Tube Cooling Blocks

Cool, freeze, heat, or thaw samples uniformly

These aluminum blocks provide better temperature uniformity than placing samples directly into a bath. Aluminum blocks may be autoclaved, high-heat sterilized, or chemically treated to decrease cross-contamination concerns. Safe for use in ice, dry ice, alcohol, liquid nitrogen, water, oil, and other temperature regulation baths. Use in traditional ice buckets and pans, or use with a Corning CoolBox™ for an ice-free option.
