stock solution of 0.5M EDTA in water (pH 8.5) is stable for months when refrigerated. I am not sure if autoclaving will degrade EDTA. If you have EDTA in powder form in your lab, you can prepare a stock solution yourself. I have observed that free EDTA acid in water will dissolve only after you put a base like NaOH and also it takes some hours to dissolve

You ran out of money for EDTA????????? Go to another lab and ask someone if you can borrow a few grams, they wont charge you. I think water is free.
