About the Test
How does it work
- Tap the unopened ampoule several times against a hard surface, such as a tabletop. By doing this, particles which may be stuck to the inside of the ampoule wall will fall to the bottom.
- Carefully remove the polyethylene sealing. Ensure that the powdery reagent contained in the cap does not fall out.
- Open the ampoule as follows: Hold the ampoule firmly at the bottom with one hand. Take the ampoule tip between the index finger and thumb of the other hand and snap it off at the predetermined breaking point by lateral pressure.
- Using the pipette provided, transfer a small amount of sample to be tested into the ampoule. Whilst transferring the sample, make sure to hold the ampoule in an upright position so that the substance falls to the bottom of the ampoule.
- Briefly mix the sample with the reagent. This can be done by tapping the ampoule with a finger.
- Once the test is complete, seal the ampoule with the screw cap.
Please refer to the instructions for use for more details.

- An overview of the expected color changes can be found in the table at the end of the package insert. The color comparisons for selected substances can be consulted at the beginning of the package insert, as well as in the referenced literature.
- The presence of GBL in the tested sample will cause a color change from white-pale pink to intense turquoise.
