Collect all papers found at a crime scene, even if you cannot see any prints. These papers are quickly examined using the Vacuum Box Model A and Model IW

Place the paper from the crime scene on the Vacuum Box and cover it with clear SP-film or IW film for lifting impression.
Use the Corona unit to charge the film.

Many quality dustprints have come from papers that had no visible marks when viewed at the crime scene.

In comparison to traditional electrostatic dustprint lifters, labs who use the Vacuum Box Model A report have a higher quality of result.

How come?

• Simple and fast to operate
• The dust particles don’t travel as far and therefore more particles are able to pass over. This results in images with more information.
• Much more sensitive than oblique lighting
• The clear film and the darkfield lighting method give higher contrast.
• The examination will not interfere with fingerprint examination or other forensic tests
• Documents will not be damaged or contaminate
