Luis -Our lab uses a very reliable 25X buffer from
ScyTek products for life science.  Not sure what type
of buffer you are looking for - they have a large
variety of buffer products.  We use their tbs/tbs+tw20
for immuno.  Already has preservatives added.  No muss
no fuss.  They offer concentrates in varying degrees
to make up to 250L. The pH stays stable & we dilute
with sterile water, no growth problems.  Contact me if
you would like more info.
