Clear UV dye?

[techun]

Do they sell any clear UV dyes? I need it to be perfectly clear for a college project we're working on. Every group needs to fill up snapple bottles with water and move them with a conveyor belt. We want to do this, then at the end light up the bottles with UV LED's to make each bottle a different color, or just surprise everyone with having the water suddenly turn green etc.

thanks

UV leds are not very effective at illuminating UV items clearly FYI.

There are some dyes but most will have a tint of the color that cant be gotten rid of.

Anyone else have any more information?

I used invisible blue from frozencpu.com and with the ratio I used it was indeed clear.
Maybe check there?

Tonic Water will glow under black lights. It's pretty clear and if you let it go flat it looks just like plain water.

you could try some dye-lite. it has a slight yellow color in bottle, but only at real high concentrations. You only need 3-4 drops in a liter and it will show up nicely under UV without any noticeable discoloration.

Here ya go...

The Feser 1 clear/UV Blue fluid looks promising. I'm still researching but I saw their little video (non-conductive!) and it's probably what I'll be using in my system.
