Suitable for testing cocaine or MDMA. These packs contain the marquis and liebermann reagent. They are over 1 year old, so they will react more slowly and the colour changes will be lighter.
These packs will be expected to last a couple of months. After 1 month you will need to test an aspirin tablet before using them to confirm they still work. You should dispose of them before January 2023.
- If the chart says “brown” the change will be more orange.
- If the chart says red then the colour change will be more pink.
- The colour change for ketamine (normally light yellow) could be too light to detect.
