cryobox (or cryogenic storage box), a specialized container designed for the organized storage and protection of small laboratory samples, such as microtubes or vials, in ultra-low temperature environments. Design and Capacity: The box features an 81-place grid (9x9 configuration). The grid is numerically indexed from 1 to 81, allowing for precise sample tracking and location identification.+1Components:Base: A solid blue bottom section that holds the internal dividers.Lid: A transparent (clear) lid that allows for visual inspection of the contents without opening the box, helping to maintain internal temperatures.Material: Typically constructed from high-quality polypropylene or polycarbonate, materials chosen for their ability to withstand extreme cold (down to $-196$°C) without becoming brittle.Format: It has a standard square footprint, designed to fit into most stainless steel freezer racking systems.
