Bromothymol blue
Posted: 03 Apr 2008, 12:07
Hi everyone,
Two of our bottles of bromothymol blue have turned an orange colour. It still works but we need some for a prac. test and I don't want them being confused by the colour. Any suggestions for getting it to turn blue again. They have only just been opened so shouldn't be off. I think we may have had this problem before but can''t remember what I did.
Thanks,
Helen.
