Mistral Herosol Pen Test
Pen Test pouches contain an Ampoule, two Collection papers and a Colour chart.
Herosol tests detect the presence of Heroin.
The user wipes or touches the suspected area with one of the collection papers. The solution from the ampoule is then applied to the collection paper and the results are checked against the colour chart to provide an instant reading of the substance.
The size of each pouch is 16.4cm x 6.6cm so they are extremely easy to carry.
