Hi guys!
-- I want to do some enzyme chromatography. Now to elute or bind proteins to the column material you need certain pH values.
I was basically wondering if a cheap pH meter will do (and, what is cheap). There are some for 12-23$ on Amazon, alledgedly with "good" accuracy. I immagine that the proteins will still elute from the column if the pH is actually 4.05 instead of 4.00 - maybe just a bit worse yield?
I would rather not mess around and invest 100-200$ in one that will master the job with excellence. But then - maybe it comes from the same chinese factory and isn't better in any way...
Any recommendations? Would be extremely appreciated!
