Can you store buffer solution in an air tight bottle to re-use it over again? I got some in a foil package but am not sure if its re-usable...
Illusion Reviewed by Illusion on . Ph buffer solution preferance After waiting 3 weeks I just received my ph tester but they didn't ship me any buffer solution and since I'm new to this I didn't even know you needed it. My question is which buffer solution is best. My tester states there are 3 kinds, #4, #7 and #10 which I have no idea what the difference is. I have to order this so I'm hoping someone can give me their input on what is best. Rating: 5
