The Micro-tool Case with tools is unique to the SGT Shortix and SGT Fix-It models, although a very similar (possibly identical) case, with a different toolset, is found on the Wenger Minathor.
It serves as a case for the round file, septum hook and ferrule remover, which are tools used in gas chromatography (GC) laboratories.
These tools screw into the Shortix micro tool holder of the SGT Shortix and micro-tool handle of the SGT Fix-It models.
