A cryo rack is a storage device used to hold cryogenic containers, such as cryovials, in a laboratory setting. These racks are typically made of metal or plastic and are designed to keep the containers at a very low temperature, typically below -150°C, to preserve the samples stored inside. Cryo racks can be used in a variety of settings, including biotechnology and medical research, as well as in the storage of blood and other biological samples.

Freezer shelf organizers are devices used to keep the items in a freezer organized and easily accessible. They come in a variety of shapes, sizes and materials and can be used to store items such as bags of frozen vegetables, ice cream tubs and frozen meals. Some common types of freezer shelf organizers include wire baskets, plastic bins, and trays. They can be placed on the shelves of the freezer and allow the items to be stacked on top of each other, making it easy to see what's inside. They are also useful to prevent the items from falling over and making it hard to reach the items at the back of the freezer.
