I prepared Potassium Phosphate buffer and i want to be using it for a long time. What are the optimum storage conditions?
Thank you
I will recommend 2°C or 25°C (or specifically the temperature under which the buffer was prepared). However, the time for which it will remain viable depends on how well is being stored and whether it is being closed or often open probably for usage during storage. Potassium phosphate buffer is an alkaline buffer and can be stored for several weeks ( probably less than 2 months) unlike acidic buffer which can be stored for 3-6 months (when the storage bottle is being open in a while) and up to 2 years (in closed bottle). I hope this help in answering the question to a certain extent.

Hello, I think that storing the buffer in refrigerator is good, but you have to check the pH for the solution before using it.
