U-tek® low temperatures gel packs protect and maintain the temperature integrity of frozen food samples, environmental samples, live or frozen tissue, serums, laboratory test samples, chemicals, pharmaceuticals and many other applications where wet or dry ice is used regularly.

These clean, economical packs are more convenient than wet or dry ice. Use for shipment of temperature-sensitive foods, chemicals and scientific materials. U-tek® materials return to gel after thawing and resist puncture. Each pack is reusable. 

Each U-tek gel pack is laminated with a metallized film exterior which provides a radiant heat barrier and resists puncture.

• Designed to provide longer protection than standard gel packs!
