Needle guide for GC inlet

thingiverse

When using Osmar (https://www.thingiverse.com/thing:3027320) as a reliable autosampler, I encountered a significant problem - the needles of the syringes consistently missed the narrow entrance of the GC (gas chromatographer). To resolve this issue, I created a guide that can be easily attached around the existing hole and greatly facilitates the syringe's access to its target. This solution ensures precision and accuracy every time! It is truly awesome! This particular design is tailored for the Trace GC Ultra by Thermo Fisher, but it can be readily adapted for other models since the open scad design is provided. If the GC inlet requires heating, a suitable printing material must be carefully selected to ensure optimal performance.
