DIY Needle Injection and Purging into Vials

Surfacing a comment from @yangcyril.cao:

Various notes on POSE 2024 Workshop

For instance, in many cases, a needle tool that draws from or injects into a septum-sealed vessel is needed. This applies to HPLC vials and vessels for a lot of air-sensitive chemistry. And possibly the ability to do simple filtrations or liquid-liquid extraction. The side camera tool is great for introducing CV to these reaction work-up steps.
