What is the shelf life of the test chemicals?

The manufacturer states that the shelf life is 18 months when I called them. I am not getting good results from my tests. Non of the tests show any color after several tries. The manufacturer is sending me some FRESH test samples. I hope that solves the problem. I notice that one of the other commenters also has clay soil.

I'm not sure what the shelf life is but the chemicals are in a capsule form so I would think as long as they are in cool, dry place they should last a reasonable amount of time.

shelf life is dated on the container: I think a year. Does not have to be kept in the refirgierator..They are great!

I'm not an expert, but to my knowledge you have to buy a new kit because the 20 tests have been calibrated to one monitor. Once the tests have been used you need a new calibration betwees test and monitor. Assume that this is mainly marketing strategy because I assume you could do the calibration at home or probably don't need the calibrations that often. Having said that, I use the monitor once a month, so shelf life is nearly 2 years.

this product's high pH, is created by natural minerals inside each bottle and should have around 5 -6 year shelf life.

I'm not sure. We are sailors and plan to take it with us when we move aboard our boat. It is my understanding that the shelf life is about a year. It is an excellent product.

My experience is that these batteries last about 2 years in use. I don't know about shelf life but I wouldn't take the chance on it.

I ordered these tests recently, and they had nearly a full 2-year shelf life remaining. The lot I got expires March 2015.

I don't know because I sent them back - I bought them for the long shelf life, but the expiry date was only months away.

I bought my 20 test kit on February 27th. The expiration date is the October 30, 2014. They should be stored in a refrigerator although the package says they will last 4 months at room temperature.

Yes, the one I bought says to use by 03/16. Whether they would be effective after that is anyone's guess, but that is as long as the manufacturer claims for shelf life.

YES. On the back side of the plastic packaging which houses the contents including the instructions and different package envelopes which contain the chemicals for the variety of tests. There are no dates on the individual test envelopes that I can see. BUT there is definitely an expiration date on the back outside of the clear plastic packaging right next to the words "Watersafe City Water Test Kit." I hope this is a clear explanation and that it helps.

According to the company, they have a shelf life of 4 years. However, there's no way of knowing exactly how long the batch you buy has been sitting around...

Using the one I got as my only reference, the shelf life is about 20 months.

I am not sure of the shelf life. I had to stop using it because it hurt my skin (made it feel like it was burning).

shelf life of herbicides varies from product to product, but if they are kept in good storage conditions (above freezing, not too hot, dry etc.) they generally last for years. An inquiry to the manufacturer will give specific advice.

The shelf life is about a year, assuming it was stored in a temperature- and humidity-controlled environment.

I don't know about the shelf life. What I can state is that would be better as a glue than anything else.
