Since its introduction in Europe in early 2001, Bluestar Forensic has become the latent bloodstain reagent of choice for crime scene investigators. Bluestar is the most sensitive latent bloodstain reagent on the market. Invisible bloodstains produce an intense blue chemiluminescence (420 to 440 nanometer range) immediately after being sprayed with Bluestar. Compared to traditional luminol reagent, Bluestar is three times brighter, is luminescent longer and is visible to the naked eye in semidarkness.

Low cost "Training" Bluestar is identical to the standard Bluestar; however, it will destroy DNA and, therefore, prevent DNA typing of the bloodstain. "Training" Bluestar is used by schools as a teaching aid, by companies that decontaminate crime scenes, and by agencies not requiring DNA typing of the bloodstain. Each box of "Training" Bluestar contains eight sets of tablets packaged in two plastic vials. Once a bloodstain has been located, the area can be sprayed again and again for further observation and photographing. Photographs can be taken with either a digital or a traditional camera, eliminating the need for expensive and sophisticated cameras and light sources. Unlike other latent bloodstain chemiluminescence sprays, Bluestar does not adversely affect DNA. After the stain has been located and photographed, samples of the bloodstain can be collected and submitted to your crime laboratory for DNA typing.
Preparing Bluestar is simple and straightforward; simply tear open the foil pouch containing the two Bluestar tablets and drop the tablets into a spray bottle containing 125 ml of distilled water. Within two to three minutes, the tablets will dissolve, and Bluestar is ready for use. Best results are obtained when Bluestar is used within three hours after mixing.
