Title: Cocaine purity testing
Post by: freedome on September 18, 2011, 08:46 pm
Hi guys,

I am desperate to provide purity test results of my batches to customers.

I cannot find any topics regarding this matter. Can anyone direct me to a thread already started if I have missed it?

If there isn't, I need something more accurate than the EZ test kit, and as easy and readily available.

I have no Chemist credentials but I was educated Chemistry at school. I am not useless and I'm a fast learner. If anyone can point me to a chemical process perhaps? Step-by-step guide with reasonably accessible apparatus.

Regards.

Hi freedome,

Would a melting point test be sufficient? Seems like it would be easy to build a setup with a thermocouple and a small button heater. If it melts around 195C +/- a few degrees it is probably very pure.

Hi Freedome,

You can do various ethanol and acetone washes of coke to remove impurities.  Weighing it in between stages can show you the % of cut. Google acetone and cocaine for instructions.

Unfortunately neither that test nor the wash will show if it's tainted with levamisole which is probably the main thing freedome is worried about

I thought it may have been due to buyers mentioning that the quality isn't as good as other vendors on SR.
