A Forensic Lab
Transcript of A Forensic Lab
A microscope with a low power, two seperate eyepieces, and two objectives to create depth perception and 3D images.
Used to view evidence up close in a 3D image.
A ventilization system that is the primary control of exposure in a lab.
Used to control exposure to toxic,flammable vapors, gases, and areosols.
Alternate Light Source
A powerful lamp containing ultra-violet (UV), visible, and infrared light.
Utilizes UV light to identify physiological fluids, such as semen, urine, and saliva through their natural fluorescent properties.
A machine used to measure the properties of light for environmental or chemical analysis, fluorscence, or raman.
Used to determine the makeup of a sample.
Solid Phase Extraction (SPE)
A technique designed for rapid, selective sample collection.
Used to clean up, recover, and concentrate the sample for quantative analysis.
A Forensic Lab
Scanning Electron Microscope (SEM)
An SEM uses beams of high-energy electrons to reveal information about the makeup of the sample.
Used to generate high resolution images of evidence samples.
Transmission Electron Microscope (TEM)
A microscope that uses electrons to see samples up to atomic levels.
Used for pathogen analysis and paint pigments.
A forensic image is the entire content of a source on a computer.
Used to store forensic files
Pictures of bullets being fired from a gun or of bullets penetrating through an object.
Ballistic photography allows forensic scientist with investigating crime scenes, scientific research and experiments.
A visual representation of a DNA sample taken by a chromatograph.
Used to help identify personal.
A machine that uses g-forces to separate particles according to their density.
Used for sedimentation of cells or to isolate macromolecules.
A device used to collect, analyse, and report digital data.
Used to detect and prevent crime
Solemate is a database that contains information about all aspects of shoes.
Solemate is used to help match crime scene prints.
FISH stands for Forensic Information System for Handwriting. It lets document examiners scan and digitize text writings.
Used for depticing letters and threatning correspondence.
NCIC is the National Crime Information Center. This is a computerized database that documents criminal justice information.
Used to help get fugitives and locate stolen property. Also to protect the public and help find missing persons.
At the crime scene, a detective is able to gather fluid off of the floor beside the victim. It is put in a sealed container and taken back to the lab. At the lab, a forensic scientist is able to use analternate light source to scan the fluid and identify it as saliva.
