hydrogen peroxide

[ri]

Hi All,
it's been a while since we talked.
Does anyone have a system for dispensing hydrogn peroxide to classes?
I favour the containers they come in with the paper valve on top.
When we use dropper bottles the teat swells dangerously....

We use dropper bottles but never tighten the dropper fully as they do expand over a couple of weeks.

They need to be able to breathe.

I have used droppers with a 2mm hole drilled in the plastic beside the teat of the dropper and this works perfectly but is a bit tricky.

The reason the teat swells is the h2 given off and you're left with water.
I tip from droppers back into black plastic storage bottles and store in fridge
never have a problem

Me too - I keep the peroxide in the fridge now, and leave the bottles empty till needed

Thanks Guys,
I am happiest with that option too. Now to convince the teachers..............
