I have not made this stain before and found the recipe in "The Laboratory".
It says 1g stain to 100ml of water. This seems really dark and strong when I made it. Much darker than the stain I already have made up.
My question is does anyone else have a different recipe/ way of making it? And does it fade with age??
Thanks

Making eosin yellowish
Re: Making eosin yellowish
My recipe says 1g stain to 100mL 75% ethanol. I haven't made any, though, so I don't know what it's like.

Re: Making eosin yellowish
Hi Lorrae
I haven't made any fresh eosin for a couple of years. I made it with water and its red. When made with water its to show movement of water in plants or in histology. When made with ethanol its for staining cytoplasm.
