Question: How many freeze-thaws is Additive A stable for? What is the half-life of Additive A?
Answer: The concentration of Additive A is carefully formulated to withstand at least 10 freeze-thaw cycles or store at room temperature for up to a week.
Heavy precipitate in Additive A is only visible when it has not been completely thawed and vortexed. In this situation you should get the solution up to ambient temperature and then vortex the tube well. Any of the precipitate should then solubilize.
