    Ok, so whilst cruising around I noticed that the question that comes up a lot is 'What does such-and-such a tool do?' or 'What would a CSI use for such-and-such a task?' Anyways, while browsing CBS.com I noticed that the CSI pages had a CSI Handbook, and that's where the idea for this thread came from! Hope it helps!

    Acoustic Reflectometry Probes:
    Probes use an audible sound signal to construct a 'one dimensional image' of a cavity, such as in a collapsed building. The acoustic pulse is partially reflected when it encounters an area of density change.

    AFIS:
    (Automated Fingerprint Identification System) Computer network that scans crime-scene fingerprints and compares them with millions of prints collected by law enforcements agencies around the state, region, country and world. A print is traced by the fingerprint expert. The tracing is then scanned by the computer, which assigns values to various features of the print. Thos values are compared to other prints already scanned into the database. The computer provides potential matches by listing a handful and providing a match percentage. Any match made by the computer is verified by the fingerprint expert who compares the inked exemplar to the print on screen.

    Agar:
    Gelatinous extract from the cell walls of some species of red algae used as stabilizer or gelling agent in food or in culture media.

    Alarm Pen:
    A small aerosol alarm that emits an ear piercing shriek recognized as an emergency call for help.

    Alginate:
    A moulding and setting gel made from alginic acid salt, which is extracted from kelp.

    ALS:
    (Alternate Light Source) Produces visible and invisible light at various wavelengths to enhance or render visible potential items of evidence (fluid, fingerprints, clothing fibres, etc).

    Amido Black:
    Dye that turns blue-black when it comes into contact with a blood-contaminated latent print.

    Ammeter:
    Instrument that measures in amperes the electric current in a branch of an electric circuit.

    Analytical Balance:
    Used to precisely weigh chemicals and tissue samples.

    Analytical Scale:
    Measures precise quantities of dry chemicals, allowing analysts to make reproducible batches of reagents and adhere to strict laboratory protocols required in forensic analysis.
    Anechoic Chamber:
    Room that absorbs sound, preventing echoes.

    Angiogram:
    Procedure that allows blood vessels and organs to be studied by injecting dye in to the bloodstream and then taking x-rays of the heart and arteries.

    Autoclave:
    Uses steam and elevated pressure to sterilize instruments.
