New Ice consists of small pouch-style "ice cubes" (45 per package), each pouch is constructed from an FDA-approved high purity polyethylene film filled with approx. 20 mL of laboratory certified pure water. Frozen New Ice provides a great alternative to conventional ice. The pouches are durable, washable, and re-freezable. New Ice may be added to a warm liquid to cause rapid chilling and there is no accompanying dilution of the liquid as the water inside the pouches melts. New Ice is great for keeping samples cold! FDA-approved Made of durable polyethylene Washable Re-useable, Re-freezable No watery mess to clean up
