BLUESTAR® FORENSIC "TRAINING" 8 APPLICATIONS This version of BLUESTAR® FORENSIC is intended only for training purposes. It has the same packaging and amount of tablets than the BLUESTAR® FORENSIC TABLETS 8 APPLICATIONS but it is cheaper so as to cut back training expenses. It will react in the same way as regular BLUESTAR® FORENSIC TABLETS do, except for DNA analysis since the "TRAINING" version destroys DNA. Therefore, it is a great product for training crime scene technicians but is definitely not usable for actual investigations. 8 pairs of tablets for 8 applications Each pack provides the instructor with the possibility to prepare 8 times 125 ml (4 oz) of BLUESTAR® FORENSIC working solution or 1L (32 oz) at once.Pack content : 2 tubes of tablets. The red-top tube holds 8 beige tablets (the reagent) while the white-top tube holds 8 white tablets (catalyst). Pack size : 65 x 47 x 26 mm (2,6 x 1,9 x 1,3 inches) How to prepare the solution To prepare the working solution, you will need to dissolve a pair of tablets (white + beige) in 125 ml (4 oz) of tap water in a bottle equipped with a fine mist atomizer. If you need more reagent, use several pairs of tablets at once.. Luminol (C8H7N3O2) is a versatile chemical that exhibits chemiluminescence, with a striking blue glow, when mixed with an appropriate oxidizing agent. It is a white to slightly yellow crystalline solid that is soluble in most polar organic solvents, but insoluble in water. Luminol is used by forensic investigators to detect trace amounts of blood left at crime scenes as it reacts with iron found in hemoglobin. It is used by biologists in cellular assays for the detection of copper, iron, and cyanides, in addition to the detection of specific proteins by Western Blot. For analysis of an area, luminol can be sprayed evenly across the area, and trace amounts of an activating oxidant will cause the luminol to emit a blue glow that can be seen in a darkened room. The glow lasts for about 30 seconds, but the effect can be documented by a long-exposure photograph. It is important that the spraying be evenly applied to avoid creating a slanted, or biased impression, such as blood traces appearing to be more concentrated in areas which received more spray. The intensity of the glow does not indicate the original amount present, but only the distribution of trace amounts of substances left in the area. http://en.wikipedia.org/wiki/Luminol
