Forensic EXPERIMENT KIT | Chemiluminescence DESCRIPTIONThis forensic kit contains Luminol which can be used to produce a chemiluminescent (light producing with very little heat) reaction. This reaction will emit a blue glow for about 30 seconds that can be seen in a darkened room. It uses copper as a catalyst, but can also use iron which is found in blood. The reaction only needs very tiny amounts of blood (1 part per million) to work. This is why it is used by forensic investigators to detect trace amounts of blood left at a crime scenes. This kit contains a copper catalyst as well as a safety lancet so you can perform the reaction using your own blood if you so wish. The kit also contains a spray bottle and instructions on how to use it to detect blood as a forensic investigator would. Luminol mixture, perborate mixture, copper sulfate, lancet, 5ml spray bottle, pipet (0.2ml). pipet (0.5ml), plaster, 2 x alcohol wipes, graduated test tube, plastic pot, nitrile gloves (medium), and a 0.05ml scoop. Safety Warning: The material in this kit is safe when using as directed. However, it contains chemicals that may be harmful if misused. Please note that handling ferrofluid can also be quite messy if handled recklessly. Therefore, we recommend this kit for hands-on use with children over 13 unless they are under the supervision of any adult to prevent any damage or injury.Delivery Item will be dispatched within 1-2 days after receipt of full payment.Payment We only accept Paypal for sales. how does it work ? The release of a photon of light from a molecule of Luminol is a fairly complex, multistage process. First for this reaction to work Luminol must be in a basic solution. This is necessary because, in neutral solution, luminol forms what’s known as a zwitterionic structure; that is, a molecule with both a positive and a negative charge. In a basic solution, it forms an anion, a negatively charged molecule which can exist in two forms (or tautomers), with the two negative charges delocalised on either the oxygen (the enol-form) or on the nitrogenous (the keto-form). A cyclic peroxide is then produced in a redox reaction involving hydrogen peroxide and a catalyst. The cyclic peroxide then decomposes to give Nitrogen and 3-aminophthalate. The reaction releases energy, which is transferred to electrons in 3-aminophthalate molecules, promoting them to their energy level. As the electrons drop down to a more stable energy level, they release their excess energy as photons of light, resulting in blue chemiluminescence.
