Do the packages have expiration dates? Strips that do not respond have been contaminated with heat, light or age. How "old" were the strips?

I no longer have the package as we have used them all up on a resinous flooring testing project, so I am sorry I cannot tell you if the package had an expiration date, but the strips did work properly and effectively.

I couldn't find an expiration date. The ones I received looked fairly new. I feel very comfortable with using them, although I am not trying to get an exact figure. Just trying to make sure my vinegar that I make is in the ballpark

We did not used to print an expiration date on the label, though now we do. They will be good for longer than the expiration indicates, but the indicator compounds can breakdown over time and quicker depending on the weather conditions. The printed expiration is two years out from manufacture.

I do not see any expiration date on the package. I just dipped one of the strips into some fermented pickle brine and on the color scale I'm on 3 which is acidic enough for my fermentation. I really haven't done urine samples that much, but each time I've used them I seem to be on the 7 color scale. I think these strips are doing a good job! One more thing I'd like to add is to make sure your strip is pretty well dried for good results.

That is the date that the strips stop working. Expiration date is on the box. Sometimes the sellers will not tell you the Ex D good if expires in a year.

July 2015. Let me sat that I use strips with expired dates routinely. They still work. The strips I received free from my doctor expired before I used them. The readings are accurately.

The strips I buy have an expiration date of at least 14 months in the future. But take note that some sellers have fresher merchandise than others.

Whenever I have ordered these strips from Amazon, they have had at least 1-1/2 years expiration from the time I got them. Hope it helps

The strips expire in 13 months. I never received an order where the strips last for a few weeks. I hope that helps.

very good question. unfortunately, I put the strips in the kit that came with monitor and discarded box when everything arrived. I do not know the expiry date. Next time I will be sure to look for this.

The numbers stamped in the foil are the expiration date. They can be hard to see. I find rolling them in the light works best.

Yes. I have ordered at least 4 times on Amazon and the expiration has been at least a year away.. More than enough time since I like to order in volume. I have been very satisfied with the expiration dates on the strips.

I'm not sure they have an 'expiration ' date. They should remain good as long as they are sealed in the foil packets.

I have no idea what the expiration date will be on the package you will receive but my recent order of two boxes of strips have an expiration date of Oct. 2015 so they are quite current.

I just ordered some strips and they expire in April of 2015 so you should be good if you order them.

I didn't see an expiration Date on the package. But they are sealed in like a foil pack. I would think it would last for many years to come. As long as the foil is not broken.

I don't know; however, all the strips I ordered on Amazon had far out expiration dates, so it wasn't a problem.

All of the strips are individually wrapped. So when you open a strip you should intend to use it immediately. There are expiration dates on each individual package, I believe they are good for over a year.

The strips I recently ordered has expiration date of 6/40/15. The expiration date is located on top of the box when you receive your shipment.
