These pucks can be loaded with 10 frozen samples mounted on SPINE format holders. Each puck is identified by an unique dot matrix. The SPINE standard is the sample holder format accepted by most of the sample changers available on MX beamlines in Europe, and elsewhere.

This tool is designed to help loading and unloading SPINE pucks with vials and sample holders.It is intended to sit in a liquid nitrogen bowl such as foam dewars and is designed to elevate the vials/sample holders from their position in the puck for easy removal and transfer to or from another holder. Without this tool, the magnetic ring on the vial keeps the samples stuck inside the puck, rendering the unloading operation very difficult to achieve.
