Sticky Side Powder is an economical and effective product for developing latent prints on the adhesive side of tape. Sticky-side powder had been shown to develop clearer prints than other pruducts used on tape such as Crystal Violet.
Sticky-side powder is very easy to mix. Simply add the powder to equal amounts of water and photo flow and mix into a paste. the paste is then applied to the adhesive side of the tape with any standard camelhair brush and allowed to set for 10-15 seconds. It may be left on longer or rinsed off sooner if desired. It can also be reapplied if desired.
Shelf life of powder; indefinite if kept in a cool dry place.

This kit contains all the components necessary to develop latent prints on the adhesive surface of tapes, labels and similar surfaces. Adhesive-side powder yields excellent results on duct tape, plastic tapes (clear, frosted and opaque), paper labels and tapes (except those with water-activated adhesives), vinyl surgical tape (excellent fidelity but low contrast). SIRCHIE®'s ASP50L powder is ideal for vinyl or plastic black electrical tape. Use it with a ultraviolet lamp. The TRA20 adhesive tape release agent allows tangled tape to be released without damage to latent prints which may be present. Complete instructions are included. NOTE: The UV lamp is no longer included in the kit.
Ninhydrin Crystals & Sprays
Ideal for developing latent prints on paper because it virtually eliminates ink from running. Use it on currency, envelopes, magazines, books and other printed documents. The spray is nonflammable. **Additional freight charges are applicable.**
Ninhydrin is one of the best and easiest methods for developing latent prints on paper, such as bad checks, robbery notes, drug pay-and-owe sheets, and threatening letters. Many latent print examiners use Ninhydrin exclusively on paper documents because it is effective and/or they do not have the proper setup and/or Forensic Light Source for using DFO.
DFO (1,8 Diazaflueren-9-One)
DFO is responsive to the amino acids present in the body protein. Research has established that DFO will develop 2.5 to 3 times more latent prints on paper items than ninhydrin used alone. If used in sequence with ninhydrin, DFO must be used first to achieve fluorescence. Mix it yourself or use the pre-mixed solution. Dip the paper documents or spray them and allow them to dry. Heat the papers using an oven or dry iron for 10-20 minutes. Examine with a Forensic Light Source and photograph the resulting latent prints. Heating the papers with a hand iron for 10-20 minutes is a bit time consuming. We recommended using an oven. Our pre-mixed solution has a non-flammable carrier and can be shipped via air.
DFO is a ninhydrin analog used for developing latent prints on porous surfaces. Its fluorochrome properties make it especially useful on multicolored surfaces where the background would interfere with subsequent photography. DFO reacts with the amino acid content of fingerprint residue, and it will not interfere with subsequent analysis using ninhydrin, silver nitrate or physical developer. In fact, some labs report that DFO use improves the results gained with ninhydrin. According to the “Manual of Fingerprint Development Techniques” published by the Police Scientific Development Branch of the British Home Office, DFO will develop more fingerprints than ninhydrin. Testing in the U.S. indicates that DFO will develop 2 1/2 times as many prints as ninhydrin. Other testingindicates that DFO is also effective for developing latent blood prints. On occasion, DFO will produce lightly colored (pink) latent prints, but its real strength is in its fluorescent properties. DFO fluorescence may be produced using ultraviolet light, BLUEMAXX™ and other alternative light sources. DFO is now packaged in a pump spray which contains 100ml of pre-mixed reagent for better control and less waste. DFO in crystal form is available for those labs preparing their own formulations.
This is a controlled heat chamber designed specifically to accelerate the development of DFO-treated latent prints. DFO is a fluorescence agent which attaches to fingerprint residues on paper and other porous surfaces and causes them to emit light when suitably viewed. It has been found to develop up to two and a half times the number of prints developed by ninhydrin. Although DFO-treated prints will slowly develop unaided, research has shown that they can be accelerated safely and significantly by the judicious application of heat. The DFC100 and DFC200 conform to the findings of current research by independent forensic investigators and laboratories toprovide an optimum acceleration environment. For efficiency, chambers are designed to allow for the hanging of multiple documents. Removable shelves allow for the development of items not easily hung. Observation through the double-pane, tempered glass door allows monitoring of development without disturbing the controlled atmosphere of the development chamber. The state of development can sometimes be judged by observing visual indicators, but is most accurately judged using fluorescence techniques. Because of its broad excitation band, excitation of DFO-enhanced prints can be accomplished with SIRCHIE®’s BLUEMAXX™ systems. Emissions are viewed through the barrier filter integrated into BLUEMAXX™ systems. The DFC100 and DFC200 feature solid-state, single set point temperature controllers with a digital readout. Although pre-set for optimum DFO development, the temperature is easily adjusted to meet individual needs. Efficient, high-temperature insulation surrounds the oven chambers while automatic cutoff at 220°F reduces the possibility of damage tosensitive papers.
The CYANOWAND™ is incredibly simple to use. Simply attach a cyanoacrylate cartridge, ignite and begin fuming. Hold the CYANOWAND™ several inches away from the suspect surface and sweep the wand back and forth. Latent prints develop as they're fumed. The CYANOWAND™ also offers superb fuming capabilities when used with SIRCHIE®'s fuming chambers. Includes all the necessary materials to process latent fingerprints with cyanoacrylate fuming. Instructions are also included.
SIRCHIE OMEGA-PRINT™ FINGERPRINT DEVELOPER
SIRCHIE®'s 16 oz. bottle of OMEGA-PRINT™ is designed for departments that process a large number of latent prints with cyanoacrylate. OMEGAPRINT ™ is supplied with four applicator bottles to maintain the integrity of the bulk container and to permit drop application to dispersal pads and disposable fuming trays. OMEGA-PRINT™ is one of the leading choices of many law enforcement agencies throughout the world.
THE FINDER™ is a unique gel formulation sandwiched between two layers of aluminum foil. Place the packet horizontally or vertically in a fuming chamber-without dripping any glue.
The CYANO-SHOT™ is one of the hottest new products to come along in the world of latent print development in quite some time. Utilizing the developmental properties of cyanoacrylate, this amazing product creates an abundant amount of heat, which decreases fuming time while providing quality ridge detail. The CYANO-SHOT™ is ideal for use with any of SIRCHIE®'s fuming chambers.
Here is a method of fuming with cyanoacrylate fumes, instantly in the field. It is no longer necessary to wait until you get back to the lab to fume evidence. After fuming, you can use your Forensic Light Source with powders and dyes to further enhance the latent prints. Use this glue fuming wand in conjunction with Redwop™, Greenwop™, Blitz-Red™, Blitz-Green™, Rhodamine, Ardrox, Basic Yellow 40, or other powders and dye stains. If you don't have either type of light source, you can always use regular or magnetic powders to dust the glue-developed prints, just like you would with any other type of glue fuming you currently do.
Using cyanoacrylates (e.g., "Super Glue" found in various instant bonding glues to develop latent prints on objects has been quite successful over the past few years. Upon placing the evidence and the glue product in an enclosed tank, such as a small fish tank, the fumes from these liquid adhesives react with the residues in latent prints to product hard, white visible impressions. The resulting visible prints can be photographed and processed with powders or chemicals.
