Shelf life on open, water based test susp

[tonyperkis]

hello, i cracked open a 10ml, water based test susp back in July, and have about 6ml left. I understand bacteria contamination can be a concern. It's been about 100 days....am I safe to still pin from this? Thanks

I just started using one again that I pulled from originally about a year ago. No issues for me.

I had an old bottle from years ago I found in my sock drawer.....used it and it was fine, although the knotting reminded me of why I quit using it

Open without a stopper? I wouldn't.

Water based is always a bit more risky, but as long as you did sanitary drawing techniques it should be just fine. Just make sure it look correct, no inclusions or unusual cloudiness or coloring.

When you say crack open, you mean without the stopper anymore? If yes then DO NOT do it

Open without a stopper? I wouldn't.

It still has the stopper, and I used sanitary drawing techniques the 4 times I drew from it. Thanks!

So, it's not open. It just doesn't have the plastic cap.

If it was properly made, it should be fine, but I'd be safe and bake or pressure cook it for a good 30 minutes before using.

I wouldnt let it get real old.
if its a true water based suspension I would worry if it went to long past exp.
Not worth and infection or bad reaction.
