Here is a link that explains PCR and what it is used for. You probably have an idea of how important it is in forensics, as DNA evidence, by watching NCIS and in medicine and research. PCR uses disposables and reagents, along with film.
PCR stands for polymerase chain reaction.
If you are interested on how I proposed to incorporate this with photonic (photo) technology, click here.
Gel based electrophoresis and PCR require various types of equipment, the simplest being a charged tank that can often be about 4x5 inches of gel or larger that works a lot like what we used to refer to as chromatography. All of this happens, usually, in a lab. C.B.S Scientific is a company that sells this type of equipment.
The results, like this, need to be recorded somewhere. An ordinary piece of film can be used, or some digital image capture device. Gel based electrophoresis isn't always very contrasty so the recording medium needs to have sufficient greyscale in order for the results to be easily interpreted.
From the ad copy: 667 film is designed for use in electrophoresis, photomicrography, photomacrography, oscillography, computed tomography, ultrasonography, and nuclear medicine. 667 is also used in preparation of real estate ads and for instant documentation in law enforcement, insurance, building construction, and architectural design.
