Cooling end-caps, cooling frames, and cooling blocks can be purchased individually or as part of a kit pairing nicely with selected bag or box to provide maximum protection. Use the cooling end-caps and cooling frames together to encapsulate the entire sample. This modular system can accommodate various sample sizes to provide a complete thermal barrier. Cooling packs come in standard 4 °C (color coded blue) and 22 °C (color coded green). Temperature ranges are 2 to 8 °C and 20 to 24 °C respectively; these ranges can be maintained up to 15 hours.

Cooling end-caps and cooling blocks include a temperature indicator label.

†Based on ambient temperature of 25°C. Estimates can vary depending on how samples are packed.
