Tool marks may be found at a range of crime scenes, including house burglaries, car crime, firearms offences.

Criminals often need to force entry when committing crimes.

Many different tools are used for this task, all usually leaving behind some indication of their use.Usually in the form of a distinguishing marks.

Tetra Scene of Crime have developed a silicon based impression material (CSI - CRIME SCENE IMPRESSION) to capture and replicate the fine detail and unique characteristics from tool impression, fingerprints, and ballistics.

As most impression materials are manufactured for the industrial engineering sector, and supplied in a range of colours and viscosities which although capture and replicate, they do not retrieve all striations and imperfections vital to forensic comparison techniques.

If the colour of the impression is to dark or light, the impression may require additional laboratory treatment to enable suitable visual comparison.

To overcome these problems, CSI is supplied in Medium viscosity and is grey in colour.

Also available in Grey Medium Viscosity , Blue Light Viscosity, Green Light Viscosity
