None, it's a tank fitting designed for water tanks and boilers so it's completely safe to use. It doesn't contain lead.
Hi, the condenser feed pipes pass through the column to produce reflux within the column. You could probably expect to get around 80-90% alcohol with this.

Hi!you can use the calculator here: ( http://homedistiller.org/calcs/cond_calc) to find how much water you will use.
Thanks for reading!I used an old still design due to limitations in the materials I could find, the largest column diameter I could get was 28mm. I also wanted to keep the cost as low as possible, but the still works fairly well.
This instructable is amazing.
Glad you enjoyed it! Thanks so much for the vote:)

Probably just peppers :)
I'm actually in the UK so I don't have to worry about that :) .(as long as I'm not selling it)
It does work, for what I need, I have produced 90+ percent alcohol with it. If you are looking for an advanced reflux still I suggest you look at the many other instructables for that sort of thing.
Love the instructable! Keep building:)
If I wanted to build an advanced reflux still I would have. I built this to be an easy and cheap intro to reflux stills.
Thanks! I'm not too good with electronics, so I might find it tricky to build sensors. Great idea though:)
Yes, I get what he means. I just meant if you used the same heater and volume of liquid, you would need to boil the water for longer than the ethanol.
This wasn't meant to be a guide on how to distill, rather a guide on how to equip yourself for distilling. I hope anyone building this will research distillation processes before using it:)
I meant if you kept the heat input the same:)
Thanks for the vote :)I'm making vodka with this still, but I have another pot still I've made a nice rum with. I did use some packing, but as you said it's probably not needed. I probably should put a thermometer in, but I usually just go by smell to test if methanol is present then measure the percentage after.
How to make a copper reflux still
Ernter's right, the tubes provide a cold surface for the alcohol vapours to condense on.
Yeah, you can use copper mesh for packing, it will help to remove sulphites, but the pipes running through the column should provide enough reflux. Its probably better to use packibg, but I aimed to do this instructable as cheap as possible, so I excluded this.
Thanks btw gertd4 :)

I think aeroponics uses misters to cover the roots in a mist. There are different kinds of hydroponics like drippers, as you said, but also DWC and NFT (nutrient film technique) hydroponics systems. This is just one kind of hydroponics:) Glad you liked the instructable :)
