ThermoSafe® U-Tek® Reusable Cold Packs
• Keeps temperature-sensitive materials cool during shipping
• Puncture-resistant exterior provides a radiant heat barrier
The nontoxic gel contained in the U-Tek® Phase Change Material Reusable Pack stays cold for long periods of time and provides a 15% longer cooling duration than standard gel packs. Maintains critical temperatures of serums, organs, test samples, pharmaceuticals and live or frozen tissue. The pack is available in three temperature levels.
The -58°F (-50°C) pack must be frozen in dry ice or a -112°F (-80°C) freezer and is intended for applications which require extremely cold temperatures. The -10°F (-23°C) pack protects products which need to be kept frozen (temperature rises 1°F per hour at ambient temperatures) and can be frozen in freezers which cool below -10°F (-23°C). The 30°F (-1°C) pack offers protection for products which require long periods of refrigeration by maintaining refrigeration for up to 48 hours.
