Hi everyone.
I have some pH4 and pH7 buffer solution for calibrating my pH probe, but is there any difference in the various products becide price ? They are all 4.01 at 25°C and 7.00 at 25°C..
I can see that I can buy it alot cheeper from Agro-culture shops than from the Aquarium shops..
Is it just the same but different price or is there anything to be aware of ?
