STK Lab
Most efficient solution for sperm stain screening on textile
As semen is most of the time deep in the fabric, STK Lab pre-impregneted and ready-to-use paper is the most effcient solution for clothes, bed sheets and any textiles evidence.
> VIDEO: STK Sperm Tracker is being used in routine by the French National Institute of Scientific Police (INPS):
“tested in parallel with Crimescope (CSS filter and orange and red glasses) STK Sperm Tracker clearly showed its ability to overcome fabric constraints (improved sensitivity) and to carry out two operations in one: both pinpoint stains and reveal their acid phosphatase activity.
More reliable, faster and easier to set than the method currently in force within the INPS, STK Sperm Tracker represents a real step forward in the forensic field.”

STK Lab is being used in Crime Laboratories in the world for more than 4 years and helped to solve thousands of rape cases.
