NINcha Fingerprint Development Climate Chambers | Ninhydrin, DFO & Indandione
Forensic Latent Fingerprint Development Chambers for Porous Surfaces
The NINcha series are purpose-built forensic climate chambers for developing latent fingerprints and trace evidence on porous surfaces using Ninhydrin, DFO, and Indandione. Available in three configurations — the benchtop NINcha S31, mid-size floor-standing NINcha M31, and large floor-standing NINcha L31 — NINcha delivers consistent, reproducible fingerprint development results under precisely controlled temperature and humidity conditions.
Porous evidence such as paper and cardboard is first treated by dipping or spraying with chemical developers, then developed inside the climate chamber following an evaporation step. This controlled environment consequently ensures optimal conditions for maximum fingerprint yield.
Many forensic laboratories attempt development using repurposed cabinets or general-purpose chambers. Unfortunately, this approach risks inferior development results, compromised laboratory credibility, evidence contamination, and mould growth. NINcha, by contrast, was engineered specifically for forensic latent fingerprint development, informed by feedback from working forensic professionals. As a result, with over 500 systems installed worldwide, NINcha is the trusted standard for fingerprint development on porous surfaces in modern forensic laboratories.
Stainless Steel Interior — Easy Decontamination & Chemical Resistance
Every NINcha climate chamber features a smooth, high-grade stainless steel interior designed for rigorous forensic use. Not only does stainless steel resist corrosive chemicals, but it also supports peroxide-based decontamination cleaners and simplifies DNA contamination removal — tasks that are more difficult and less effective on painted or plastic surfaces.
Furthermore, all internal components — including evidence shelving, hanging rods, and hooks — are stainless steel, making them rust-resistant and dishwasher-safe for laboratory cleaning protocols. In addition, all interior accessories are tool-free removable, allowing fast, thorough chamber decontamination between cases.
In contrast to competing products, NINcha’s open-chamber design eliminates hidden air channels, thereby reducing contamination buildup and making the chamber significantly easier to clean.
Additionally, an optional external ventilation hookup is available on all models for laboratories requiring ambient heat reduction or complete shutdown of circulation and humidification systems between cycles.
Intuitive Touch-Panel Control & Fully Customisable Development Cycles
NINcha is operated via an easy-to-use touch-panel display with full parameter monitoring throughout every development cycle. In particular, the system includes pre-programmed development cycles for common forensic developers including DFO, Ninhydrin, and Indandione, enabling one-touch operation for routine casework.
Beyond that, users can modify pre-programmed cycles or create entirely custom development cycles — consequently future-proofing the system for new chemical developers as they enter the forensic market. Furthermore, cycles can run automatically or be controlled manually, giving laboratory staff full flexibility.
USB Process Datalogger — ISO 17025 Quality Assurance
Reproducible, documented results are critical in forensic science, particularly for ISO 17025-accredited laboratories. For this reason, all NINcha development cycle data is automatically logged and can subsequently be exported via USB for quality assurance records and case documentation.
Moreover, the integrated datalogger software allows users to generate custom QA reports featuring department logos and information, exportable as image or text files — thereby streamlining compliance and chain-of-custody documentation.
Integrated Air Filtration — Preventing Cross-Contamination Between Cases
Developing porous evidence such as paper or cardboard can generate dust containing DNA and other trace material. As a result, NINcha’s open-circulation air filtration system actively removes dust and contaminants from the chamber airstream, significantly reducing cross-contamination risk between evidence items.
In addition to this, NINcha uses coded, developer-specific filter units to further prevent cross-contamination between Ninhydrin, DFO, and Indandione development. Specifically, the chamber automatically recognises the inserted filter and restricts cycle options to the correct developer type — thereby eliminating user error and protecting evidence integrity.
NINcha P31 — Portable Fingerprint Development Chamber
The NINcha P31 brings laboratory-standard latent fingerprint development to the field. Specifically, it is built into a compact rolling case with an extendable handle, making it ideal for developing porous evidence at crime scenes or remote locations without compromising development quality.
In addition, the NINcha P31 portable fingerprint development chamber offers the following key features:
- Compatible with Ninhydrin, DFO, and Indandione developers
- Stainless steel interior walls and removable evidence racks
- Accommodates evidence up to DIN-A4 (A4) sheet size
- Full touch-panel control with pre-programmed and custom cycles
- Integrated USB datalogger for field documentation and ISO compliance
- Large glass door panel for continuous visual monitoring during development
- Auto-locking door during active cycles to protect evidence integrity
