Reduce sample handling time and the need for several racks when working with samples for cold temperature storage. Patent-pending opening and closing mechanism allows the rack to expand, creating needed room for sample manipulation. Then simply collapse the rack back to its compact form and it is ready for the freezer.

• Clear lid locks the rack together for safe handling and transportation.
• Wells have a center depression to stabilise conical tubes and a cryogenic vial lock for one handed cap removal.
• Stackable.
• Autoclavable.
• With alphanumeric well identification.
• Will fit into standard 52 mm freezer racking.
