[Towlie]

Can anyone explain how to use this pH buffer there are no instructions just a few illustrations on the bottle

Thanks for the advice but i think i didn't explain properly

Its not pH up/down its a liquid buffer to calibrate your pH pen one is pH 4 the other is pH 7 I have used the crystals to calibrate the pen before but never liquid do I dip the pH pen into the bottle like the instruction on the bottle show or do I make a solution in another container

pour a small amount into a cup in order to test pen.throw out after use to avoid contaminating the bottle.
