NINcha from Attestor Forensics is a concept for “a real forensic climate chamber”, which focuses particularly on the development of Ninhydrin, DFO and Indandione treated fingerprints.

For better contrast between fingerprint and background an increasing number of laboratories change to a development of Ninhydrin-treated evidence at temperatures slightly above room temperature but still at high humidity. The majority of cabinets on the market struggle with this demand as high humidity at low temperature increases the risk of condensation, potentially damaging evidence. NINcha lets the user have high humidity levels even at low temperatures and features a unique system to avoid condensation. Certain chemical treatments need to be undertaken in a certain order. DFO treatment for example, needs to be done before Ninhydrin otherwise it will not work. If the majority of the work undertaken by any forensic cabinet is Ninhydrin, then all the filtration units will be saturated with old Ninhydrin fumes and minute paper particles and any future DFO treatments may be contaminated with this residue Ninhydrin.
