LaMotte Hardness 1 Buffer, 1-oz, 30-ml Bottle

The majority of LaMotte reagents have an expiration date printed on the label. Knowing the expiration date can prevent wasting reagents and avoid using reagents that are long past their shelf-life but are presumed to be acceptable because they have only recently been opened.

Reagent Storage Guidelines
Reagents should be stored at room temperature (22°C) and away from heat, humidity, moisture, direct sunlight and cold conditions. The storage temperature should be kept as constant as possible, without large fluctuations in temperature. Reagents should not be kept refrigerated, unless specified otherwise in the kit instructions or packing literature for the reagents. Reagents should not be stored in vehicles, utility rooms, pool and pump houses, or other environments where conditions may be harsh. Exposure to such conditions will compromise the quality and stability of reagents and shorten the reagent shelf life.

Expiration Dates
If the expiration date is not printed on the label, it can be calculated from the reagent lot number. On the lower edge of the label for each LaMotte reagent is a six (sometimes seven) digit lot number. The first two digits of the lot number identify the week of manufacture. The third digit identifies the last number in the year of manufacture. For example, a reagent with a lot number of 4951222 was manufactured the 49th week of the year 2015. A reagent with the lot number of 2941222 was manufactured the 29th week of the year 2014.

If the shelf life of the reagent is unknown, one year from the date of manufacture is a good rule of thumb.
