Description
Suitable for testing cocaine or MDMA. These packs contain the marquis, froehde and liebermann reagent. They are several months 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 May 2023.
Examples:
- 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.
