NINcha Series - Ninhydrin, DFO and Indandione Fingerprint Development Chambers

With the NINchaseries, Attestor Forensics offers three different sizes of climate chambers, especially designed for the development of fingerprint evidence. 

Evidence is usually treated with Ninhydrin or DFO by bathing or spraying. Following this actual treatment process, for an optimum result, the samples need to be developed under given temperature and humidity conditions. Many forensic laboratories simply "dry“ the treated evidence in vented extraction cabinets. Other laboratories utilize industrial ovens or climate chambers, originally designed and developed for other purposes and other applications, e.g. as incubators for bacterial cultures or the like. Where many aspects - important for forensic use - are neglected, other features are achieved at the expense of ease of forensic use and user safety.

In forensic use, evidence should be developed under homogenous conditions with fixed parameters. Further it should be possible to observe the develop-ment and document the relevant parameters for quality control. NINchaenables all of this, using a user friendly, multi-lingual touch panel control with a USB data logger and a novel and innovative air stream concept. 

In difference to many other climate chambers, NINcha monitors and controls the temperature and humidity not directly in the air stream at the air outlets but uses actual values inside the cabinet. For a forensic climate chamber it is im-portant, that it can be easily cleaned and kept free from DNA contamination. NINchatherefore features an integrated air filter system, which reduces the amount of airborne dust from samples that might be loaded with the develop-ment chemical. Any area that comes in contact with the air stream is easily accessible for cleaning off remaining Ninhydrin or DFO particles. This limits the risk if cross-influencing of the various chemicals used and reduces the cleaning effort. Many other features round off the innovative NINcha concept.
