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.
