CSI superglue Not all

CSI superglue Not all superglue is the same! Our SI5 EthylCyanoacrylate Adhesive has been specifically formulated for fuming applica ons. This product is triple dis lled to produce the highest purity on the market. The purity of the formula on is directly related to the stability and performance of the product. Our 16 oz bo le comes with 5 smaller 1 oz bo le CS-0112 CS-0113 CS-0112B 1 oz Bo le 16 oz Bo le 5 x 1 oz Empty Bo les Aluminum Reservoirs This CA fuming aide is used for hea ng and vaporizing liquid Super Glue. CS-0023 CA Aluminum Reservoirs, 25/pk un-du® Un-du® Is an acid free adhesive remover, ideal for unraveling rolls of adhesive tape, such as duct tape, or other types of tape. Will also remove adhesives on paper, glass, plas c, walls, wood, clothing, finished vinyl, leather, upholstery, carpet, wood furniture, metal, and more. Fingerprints on the s cky side will remain intact. CS-0025 un-du solu on, 4 oz (120 ml) bo le Wet Powder (Formerly WetWop) Excellent for developing latent prints on the adhesive side of tapes and labels - including duct tape, masking tape, plas c surgical tape, double sided foam tape, clear plas c tape, reinforced package tape, adhesive bandages, packing labels and other light-colored adhesive surfaces. Select black or white powder for surface contrast. CS-0093 CS-0092 Wet Powder, White, 250ml Wet Powder, Black, 250ml

ULTRA PURE CSI DFO DFO (1,8-Diazafluoren-9-one) is a reagent that (like ninhydrin) reacts with the amino acids present in fingerprints. The areas of applica on are the same: porous surfaces like paper, unpainted wood and the like. A fingerprint developed with DFO is less visible in white light than a er treatment with ninhydrin but with green light (about 530 nm), it fluoresces strongly. The fluorescence is viewed and photographed through orange or red filter (goggles). Our DFO is prepared exclusively for Crime Sciences Inc. by the Casali Ins - tute of Applied Chemistry. Purity makes the difference, and our DFO is of the highest purity (>99%), with each batch analyzed by HPLC, with a cer ficate of analysis available. Don’t take a chance: eliminate one more poten al variable in your formula on, by only using our highest purity material. We can supply any size vial you require! CS-0128-025 DFO (1,8-diazafluoren-9-one), 0.25g CS-0128 DFO (1,8-diazafluoren-9-one), 1 g CS-0128-5 DFO (1,8-diazafluoren-9-one), 5 g CS-0128-10 DFO (1,e-diazafluoren-9-one), 10g ULTRA PURE CSI 1,2-Indanedione Indanediones can visulalize latent fingerprints as well as, or even be er than, DFO. Its ease of prepara on, lower cost, and good solubility make it an excellent addi on to your fingerprint development arsenal. Professor Yosef Almog, former head of the Israel Police division of iden fica on and forensic science (DIFS) and now a researcher at the Casali Ins tute of Applied Chemistry, coordinated the team that developed the reagent, including Professor Madeleine Joullié and her graduate students, Dr. Diane Hauze and Dr. Olga Petrovskaia, from the University of Pennsylvania (Upenn). During the evalua on of the compounds at the U.S. Secret Service (USSS) by Dr. Tony Cantu and Robert Ramotowski, it was discovered that these compounds were also capable of visualizing latent prints. The powdered compound is very stable. However, working solu ons should be made up whenever needed and should not be kept for extended periods. Like Ninhydrin, latent prints visualized with Indanediones can be treated with zinc chloride to slow the fading of visible and luminescent detail. In general, an increase in fluorescence is also observed a er treatment with zinc chloride. Prints developed this way fluoresce at 530 nm like DFO, and can be viewed with a filter at 570 to 590 nm. Picture on le shows a fingerprint cut in half, and treated with DFO on le side, and 1,2-IND on right side, under green light. CALL FOR A COMPLETE PAPER ON 1,2-INDANEDIONE - we can supply any size vial you require! CS-0130-025 1,2-Indanedione, 0.25 gm CS-0130 1,2-Indanedione, 1 gm CS-0130-5 1,2-Indanedione, 5 gm CS-0130-10 1,2-Indanedione, 10 gm Adhesive-Side Developer DARK 7 oz (210ml) For developing latent prints on the adhesive side of tape, ASD7D and ASD7L are pre-mixed, thick liquids that are applied to the surface with the dauber applicator. Can be used to develop prints from masking, duct, clear, cellophane, brown packaging and nylon reinforced strapping tapes. The SI-ASD7D is 7 oz. dark. The SI-ASD7L 7 oz is light.
