NIK Test C – Barbiturates

The NIK Barbiturates Test (Test C) utilises a Modified Dille-Koppanyi Reagent to provide a professional-grade solution for the presumptive identification of barbiturate compounds. Because sedative-hypnotics can be difficult to distinguish from other powdered substances, forensic investigators use a systematic testing sequence to ensure accuracy. Specifically, professionals deploy Test C after obtaining a “no change” result in Test A and Test G, followed by an orange result in Test I.

The NIK system features a heavy-duty, reinforced plastic pouch containing two separate chemical ampoules. This sequential process allows for a controlled chemical reaction within a single, secure unit, reducing the risk of false positives. To perform the analysis, an investigator places a small sample into the pouch and breaks the internal glass ampoules in order. A positive result for barbiturates follows a specific pattern:

Safety remains a top priority in the design of the NIK pouch. Because the reagents remain sealed within the reinforced plastic, the user avoids any manual measuring, mixing, or dispensing of hazardous liquid acids. This self-contained design eliminates the risk of chemical burns and ensures the sample stays uncontaminated during the testing process. Each pack contains 10 individual test pouches, providing a portable and cost-effective solution for high-volume field work.

The reagents in these pouches maintain an indefinite shelf life when stored in a cool, dark environment. However, users must avoid prolonged exposure to strong sunlight or extreme heat to maintain chemical stability. Please note that since these kits originate from a USA-based supplier, a lead time of over 28 days may apply if the item is out of stock.
