I don’t know about you guys but I use a lot of 3 ml pipettes for small doses of things like pH up and down. Problem is I always lose them or mix them up.

Here is a cheap and easy solution.

Needed: Duct tape, 7/16″ coaxial cable staple.

Pull the nail out of the staple

Make a double sided piece of tape and tape it to the bottle of nutrient

Stick the staple to the bottle and add another piece of duct tape around the back of the staple

Now you have a pipette holder.
