The MVC/D range of fuming cabinets are the latest and most advanced range of systems for the development of latent fingerprints with cyanoacrylate monomer.
The cabinets can be operated in either manual or automatic mode and have been designed to accommodate both cyanoacrylate and PolyCyano UV, a new one-stage cyanoacrylate/fluorescent compound which treats the cyanoacrylate deposits on latent fingerprints with a fluorescent stain simultaneously eliminating the need for subsequent staining.
The updated MVC3000/D3, MVC1000/D2 and MVC1000/XL cabinets also include a number of new features including internal LED illumination, for improved visualization of developed fingerprints, and redesigned glue heater and steamer units, both of which contribute to reduced fuming cycle times and greater levels of control throughout the fuming process.
Cyanoacrylate or superglue fuming is a commonly used method of developing latent fingerprints on a wide variety of surfaces.
When cyanoacrylate glue evaporates it reacts with the amino acids, fatty acids, and proteins in the fingerprint and moisture in the air to produce a visible white material that forms along the ridges of the fingerprint. This can be photographed as is or further enhanced by dusting with a colored powder or by staining with a fluorescent dye. Fingerprint fuming using PolyCyano UV, a compound of cyanoacrylate and a fluorescent dye, works in much the same way as detailed above, however, the material formed along the ridges of the fingerprint is immediately fluorescent under UV illumination and does not require a secondary treatment.
Robust construction and trusted technology separate MVC/D fuming cabinets from all competitors.
THE ONE-STEP FLUORESCENT FINGERPRINT FUMING PROCESS
Robust construction and trusted technology separate MVC/D fuming cabinets from all competitors.
The Foster + Freeman MVC/D range of cyanoacrylate fuming cabinets and the MVC lite portable fuming systems are designed to accommodate the use of the PolyCyano UV one-stage chemical staining process.
Exclusive to Foster + Freeman outside of Japan, PolyCyano UV dramatically reduces fingerprint processing times by combining cyanoacrylate monomer with a fluorescent stain in a one-stage fuming process inside the cabinet.
Whilst standard Ethyl-2 Cyanoacrylate evaporates at 120°C PolyCyano UV requires further heating to 230°C. To achieve this increased evaporation temperature all Foster + Freeman MVC Cabinets now feature a dual-temperature heating unit, while older cabinets can be upgraded in the field.
Once evidence has been treated with PolyCyano UV, fingerprints can be seen to fluoresce brightly under appropriate illumination; Crime-lites are ideal for such examinations.
PolyCyano was developed by:

Choose to run automatic preset fuming cycles or take full manual control of every stage of the development process.
Operating under automatic control, the complete humidification, cyanoacrylate fuming, and fume extraction process proceed without operator intervention according to recommended preset parameters.
Under manual control, each phase of the development process is initiated separately, enabling the operator to extend or terminate the fuming process for best results.
The health and safety of the operator is paramount. Once the fuming process has been activated safety interlocks prevent the door from being opened until the cleansing process has been completed at the end of the cycle.
All MVC/D cabinets feature self-contained cleansing systems consisting of high capacity, fan-driven, activated carbon filters.
The cleansing process occurs at the end of each complete fuming cycle and when the cabinet is not in operation automatically for a short period every ten minutes to eliminate any build up of cyanoacrylate vapor.
The MVC/D of cabinets have been designed to accommodate either Cyanoacrylate or PolyCyano UV, a new one-stage glue/stain process for developing fluorescent fingerprints, without the need for further chemical staining.
During the development process fans continually circulate the atmosphere in the chamber to ensure that fingerprint development is uniform while sensors monitor and control the internal humidity to maintain optimum conditions.
Toughened glass panels on each side of the MVC/D cabinets afford the operator a 360o view of evidence throughout the fuming process.
Safety interlocked UV-C lamps are available for all MVC/D cabinets to provide DNA decontamination. Emitting high energy shortwave UV at 254nm, the lamps will destroy exposed DNA adhering to the internal surface of the cabinet.
One lamp is recommended for the MVC/D 1000, Two for the MVC/D 3000 and Three lamps for the MVC/D 5000 which must be ordered with the cabinet.
UV-C lamps can be retrofitted to MVC1000 cabinets in the field. MVC3000 and MVC5000 cabinet upgrades require factory modification.
