Reagent testing kits: Difference between revisions

Line 148:

Reagents are primarily sulfuric acid with other potentially dangerous chemicals, and are strong enough to burn skin and clothing. Keep out of eyes and mouth. Wear latex gloves when handling the bottle and cap. If you get some on you, then wash quickly with soap and water. Wash testing surfaces with soap and water as well. Dispose of any unwanted reagent down the sink with running water and baking soda. Store all testing kits in a cold, dark place such as a refrigerator between uses.

*Avoid exposure to direct sunlight or heat

*Avoid exposure to direct sunlight or heat to extend the shelf life

*Store upright to avoid leaks

*Keep in a safe place away from children

*Read information about expiry date, since many reagents tend to lose efficacy over time

*It's possible to store reagents in the freezer for a longer shelf life. Note that before use the reagent needs to be at room temperature. Do not open the reagent before it has reached room temperature or ~~water~~ from the air will condense water into the reagent. Liebermann reagent cannot be stored in the freezer only in the fridge.
