Freezing Tube Box

A freezing tube box, commonly referred to as a cryobox, is a specialized container designed for the safe and organized storage of cryovials – small tubes used to hold biological samples at extremely low temperatures.

Material

Cryoboxes are predominantly constructed from polypropylene, a robust plastic chosen for its resistance to low-temperature fracture, chemical inertness, and autoclavability. Some specialized boxes utilize polycarbonate for increased durability or conductivity. The internal dividers are typically made of the same material.

Purpose

The primary purpose of a cryobox is to maintain the integrity of biological samples during long-term storage in freezers, typically at -80°C or in liquid nitrogen (-196°C). They protect samples from contamination, physical damage, and temperature fluctuations. Organization is a key function, allowing for efficient retrieval and tracking of valuable specimens.
