NINcha NXT Ninhydrin / Indandione / DFO Development cabinets

The Benchmark Reinvented

For decades, NINcha has been the reference system worldwide for the development of Ninhydrin-, DFO- and Indandione‑treated fingerprint evidence. Trusted by leading forensic laboratories, it set the standard for reliability, repeatability and high‑contrast results. Now, the next generation of NINcha continues this legacy — faster, smarter, and more intuitive than ever.

The NINcha series is a family of forensic climate chambers specifically designed for the development of fingerprints on porous surfaces.

User-programmable cycles, simple operation, and ISO 17025-compliant process data acquisition offer Ninhydrin, DFO & Indandione fingerprint development that is unmatched in the market.

With over 1000+ units sold worldwide the NINcha is a popular, trusted and validated system used extensively, with many police forces in the UK and Ireland also adopting this system.  The system operates in accordance to the UK’s Fingerprint Visualisation Manual (FVM) directives set by CAST/DSTL.

With the NINcha series, Attestor Forensics offers three different sizes of climate chambers, the benchtop model NINcha S32 and two larger floor standing models NINcha M32 and NINcha L32, all of which with in built automatic pre-programmed cycles for the development of chemically treated fingerprints with either Ninhydrin, DFO or Indandione.

Features

• Fast fingerprint processing with high workflow rates Recovery times in less than 5 minutes for Ninhydrin, DFO and Indandione (S31 model). Operates within the UK FVM requirements at 80 Celsius and 62 % RH for NIN development.
• Pre-Programmed Treatment Cycles for Ninhydrin, DFO and Indandione ensure simple operation and consistently high quality of evidence development. Parameters and timers can be adjusted by a user to his demands. In addition a manual mode is available which can be used to treat high thermal mass objects but is also aimed to future proof the cabinet so if any new chemical treatment process is approved in the future the manual mode can be set to a user specific T and RH value for this specific process.
• Anti Condensation design  Highly insulated chamber prevent water condensation during the development cycle eliminating evidence damage.
• Brand new multilingual touch panel provides clear workflows, guided operation, and instant access to all key functions. All key parameters are automatically recorded by the data logger, supporting quality management documentation.
• Redesigned thermal architecture ensures significantly improved process stability. Dual top and bottom heating system providing significantly faster system readiness and recovery times.
• High-contrast lighting Integrated cold-white LEDs ensure optimum visibility, switchable to intense green lighting for exceptionally high contrast for evidence treated with Ninhydrin or Indandione(-Zinc).
• USB Data Logger  Records date, time, temperature and humidity settings in 30 second intervals.  Data can be plotted graphically with software provided.
• Variable Shelving Concept The carriers on the inner sides of the chamber are suitable for the usage with easy to clean metal grills and hanging rods.
• Air Filter and External Ventilation In order to limit cross-contamination and reduce the cleaning requirements, a special air filter system has been integrated into the cabinet to clean out chemical loaded evidence abrasion particles or dust. The filters are coded to prevent the use of Ninhydrin, DFO or Indandione filter units with the wrong process. Alternatively or additionally, the cabinet can be upgraded for external ventilation with process controlled air inflow and exhaust valves.
• UV-Decontamination Unit For easy elimination of DNA inside the cabinet, a short wave UV illumination unit can be fitted. The control system automatically detects, when the unit is placed inside.
• Water Supply and Drainage  Integrated into the cabinet is a tank for distilled water as well as a container for accumulated condensed water. The touch panel display informs the user about a due re-fill or drainage.  This makes the NINcha not reliant on water plumbing and therefore can be used any where in the laboratory provided there is access to mains power.
• Deflagration Protection  A novel locking mechanism for the door prevents too high pressure inside the cabinet, built up e.g. by steam pressure to escape for increased user safety. The door opens to the right by default. On request it can also be offered with hinges on the left side.
• Easy clean design  The innovative design makes the cleaning and maintenance of the NINcha system very simple
• Clear visibility on the evidence at all times   The unique design prevents condensation build up on the window allowing the user to monitor the development process at all times
• Low cost of ownership The system is very simple and easy to maintain.  The system is built from durable stainless steel which will not rust and provide many years of operation. Annual calibration costs are also very low.
• Serviced, maintained and ISO17025 calibrated from our UK trained staff  With any core lab equipment maintenance and optimal performance is critical.  Our trained UK staff provide on site support, service and ISO17025 traceable calibration services.
