Forenstix-Phenolphthalein Blood Test

Box of 8

The Forenstix series of disposable chemical applicators was designed to provide the crime scene investigator with the ability to conduct presumptive chemical field tests utilizing simple methodology and a minimum of equipment. The Forenstix applicators feature an absorptive sampling pad on the end of a plastic tube containing glass crush vials with premixed chemical reagents. Simply remove the cardboard protective cap, moisten the pad with the included distilled water, rub the pad on the suspected stain to transfer a sample of the stain to the pad, break the crush vials in the plastic tube, gently squeeze, and observe a color change to indicate a positive presumptive reaction. The Forenstix series of disposable chemical applicators are packaged in boxes of eight tests and include a dropper bottle of extraction fluid, and complete instructions.
