    How many years will this apparatus last? I would like to make use of this design

      Depends on how well you handle it. It's hard to not accidentally chip it when you're cleaning it.

    How much essential oil did that amount of material yield?? I’m trying to figure out if a smaller 250-500mL set up works or if I should just buy a still where u can put 50L+ and maybe make spirits 🤔

      What are your goals for using it?

      I have various herbs at home. Fragrant flowers. Lemongrass. Lavender - I do use a diffuser for aroma therapy… my wife makes her own body butter so essential oils would be good. But I also wouldn’t mind making a gallon of whiskey. I’m wondering if bigger is better or if small-medium will do for my needs.

    Consider using a Clevenger apparatus or a Dean Stark trap in place of the separatory funnel . Also you can prevent over pressure by using a couple of cotton balls on top of the still head instead of a thermometer. The thermometer is not needed in this setup

      Thanks for the input. Worthwhile considerations indeed.
      FYI: the thermometer was to record the speed of the temperature increase

      @@kgharding29 I use a hand held laser thermometer made by Klein Tools. It allows me to check temp at any point in the system. It's quite accurate. It registers in both F and C.

    Hello!! Thank you for this beautiful and precise demonstration. It would be really helpful if you could help me with a doubt. Actually, I have been trying to extract pure essential oil from Neem Leaves (crushed to powder) using a steam distillation apparatus and for my solvent I have been using ethanol and methanol in a 50:50 ratio Am I on the right path? If you could guide with any of your suggestions and knowledge, it would be really helpful for me.

    • @kgharding29

      We have been avoiding solvents as much as possible. So while I know its possible, the exact ratios are something I do not know.

    Why dont u mix the lavender with water instead of putting lavender and water alone in a balloon ?

    • @kgharding29
      @kgharding29  6 місяців тому +1

      In some experiments we do. One of our reasons to avoid mixing is to be able to separate the biomass from the hot water more easily at the end of the experiment, and start a new run with water that is already somewhat heated.
