Morning all!
Been having a browse through the forums but can't find any particular threads on the subject. Also getting a bit of conflicting information from other websites...
How do you guys store your PH pens?
So you dont want to let them dry, I've read you should store them in distilled water, i've also read you should NOT use distilled water
Same goes with calibration solutions, some say ph4, others say thats crazy and 7 is the go. Some just use tap water.
Want this thing to last as long as possible and I like to look after my stuff! Thoughts or pointers in the right direction would be great!
