Question
What is the expiration date of the StablCal® turbidity standards before and after opening?
Summary
Expiration date of StablCal® turbidity standards
Answer
The bulk size (100 mL, 500 mL, and 1 L bottles) StablCal® turbidity standards have a shelf life of 720 days unopened. After the bottles are opened, shelf life can vary due to storage conditions. It is recommended to use the Stablcal® within 30 days of opening the bottle.

See How can I stabilize my bulk turbidity Stablcal® standards to make them last longer? for information on extending the shelf life of the StablCal® solution after opening.
