Please add a siphon mode to droppers/syringes that lets you draw out specific ingredients from a mixture.
It’d only be possible wearing beer or chem goggles, and maybe its not exact. So you can only draw impurities out of the mixture, but it’ll still take trace amounts of what you aren’t filtering. Squirt the dropper into a sink, so it leaves a chem in the glass that you want.
It wouldn’t be 100% of what was in the original mixture, maybe only about 50%, but it’d be pure, so you can actually use it for drink making or bombs.
This would give more options for interesting chemistry combos to antags, or bartenders who want to make their own back alley medbay.
