Specimen Transport Coolers, 0°C for Reagents, Enzymes and Temperatue Senstive SamplesMini Coolers keep reagents, enzymes, and other temperature sensitive items cool on the bench for up to one hour. An excellent alternative to ice buckets, mini coolers are filled with a non toxic gel contained in a tough polycarbonate shell. The insulating gel ensures consistent temperature on the bench or in the freezer as protection from temperature fluctuations. Coolers are supplied with a keyed lid with printed grids for easy sample identification.
