Other - CWE - A Question or two.

[3xtr4]

Hey,

SWIM is looking to do his first ever CWE on om Nurofen Plus tablets - which contain codeine and ibuprofen in a 12.8 / 200mg combo.

SWIM is looking to use 10 tablets for his first time, giving a target dose of 100mg of codeine - allowing for up to 20mg to be lost during the process. This will equate to 2000mg (2g) of ibuprofen if it screws up.

1. SWIM was wondering why you need to use hot water to dissolve the tablets and then cool the water. Why can't you just use cold water in the first place, since codeine phosphate is more soluble in cold water than it is in hot water and ibuprofen less soluble in cold water, so even less ibuprofen will dissolve?

2. SWIM would also like to know about the end solution. Should it be clear or milky? Does milky = more ibuprofen or is codeine solution naturally milky?

3. Finally, SWIM would like to know of any issues that people have had simply using cloth / t-shirts as a filter. SWIM is worried because coffee filters are very fragile and he would like to squeeze the leftover sludge for the last few drops of codeine.


Thanks!!
