Cold water extraction: Difference between revisions

Line 5:

==For a whole batch==

{{GenericPanel/warning | title=The potency of the dried weight before and after the extraction can differ a lot~~. 50% (25% solvents, and 25% insoluble impurities) has been discarded, reported from people who initially though they possessed a "pure" substance~~. So it's extra important to [[dosage]] properly after the extraction!

For improved extraction, it's recommended to do an acetone wash (not covered in this guide) before you do the CWE, but it is not required.

Line 23:

# Throw away the impurities.

# A main advantage of extraction is to calculate how many percentages that have been cut. However, it is not uncommon that the purity will be twice as strong. To avoid accidents from impulsive eye balling, you can cut it will glucose powder which is also water-soluble.

===Example purity after extraction===

# 40% loss in drying.

# 15% loss in acetone wash.

# 20% cold water extraction.

Purity: 100−(40+15+20) = 25%
