Every time I have found no vacuum in a vial, I also had a split along the top of the crimp due to me removing the cap.

@Eleanor I bought the same kit of reta that Jeff had multiple tests of like 99.7% purity. I always filter but a solid source of peptides guaranteed 99% purity. When other vendors speak of 95% minimum I avoid them.
