Easily identify stored samples with Crystal Industries metal tags designed specifically for aluminum cryo canes. These durable tags are manufactured from high quality metal to ensure long term performance in cryogenic storage conditions. Each pack contains 12 tags and is available in five distinct color options including red, yellow, green, blue, and white, allowing laboratories to create clear visual identification systems for stored vials and samples. The tags securely clip onto the ends of aluminum cryo canes so that samples can be quickly located without removing multiple containers from storage racks. Their strong metal construction resists bending or damage during routine handling while maintaining visibility in ultra low temperature environments such as liquid nitrogen storage systems and cryogenic freezers used for long term biological sample preservation.
