What equipment is used in a forensic lab?
Forensic laboratory equipment ranges from instrumentation you would see in a general laboratory, such as microscopes, fume hoods, chromatographs and spectrometers, to equipment used for specific forensic analysis, like cyanoacrylate fuming chambers for lifting of latent fingerprints.
What tools do forensic scientists use to collect evidence?
They also bring themselves the following tools:
- crime scene tape.
- magnifier.
- flashlight.
- tweezers.
- swab.
- paper sacks and envelopes.
- measuring tools.
- orange evidence flags.
What is the most important apparatus for forensic investigation?
High-Powered Microscopes Another important tool in a forensic laboratory is a microscope, since most of the evidence collected in crime scenes are minuscule and cannot be easily identified or analyzed by the naked eye.
How are microscopes used in forensic science?
The microscope is used by forensic scientists to locate, isolate, identify, and compare samples. Finally, physical properties such as color, solubility, melting point, and boiling points can also be used to identify and compare forensic samples.

What are the tools of investigation and the basic equipment of the investigator?
In order to adequately sketch or map a crime scene, a crime scene investigator should always have a compass, ruler, graph paper and pencils and marking pens in his or her kit. Depending on artistic ability, one might also carry professional drawing instruments.
What are the 3 main objectives for a forensic investigator regarding evidence?
The main objectives of any crime scene investigator are to recognize, preserve, collect, interpret and reconstruct all the relevant physical evidence at a crime scene. This evidence is send to forensic laboratories to be examined and provide the investigator with information that may help solve the case.
Which microscope is most commonly used in forensics?
The stereoscopic microscope is the most frequently used and versatile microscope found in the crime laboratory. When you increase the compound microscope magnification its field of view decreases.
Which type of microscope is most useful to forensic scientists and why?
Electron microscopes provide much higher magnifications. They are of two basic types – the Transmission Electron Microscope and the Scanning Electron Microscope. The latter has a much greater depth of field than the optical microscope. This instrument is very useful for forensic purposes.
What is gel electrophoresis used for forensic analysis?
Agarose or polyacrylamide gel is the most commonly used reagents in gel electrophoresis. DNA differences between two people can be found with the help of short tandem repeats (STRs), which are a particular type of repeat that is variable and can be measured. During the forensic analysis, around 1 nanogram of DNA is first extracted from the sample.
What is model S2 gel electrophoresis?
The Model S2 Sequencing Gel Electrophoresis Apparatus is designed for fast, uncomplicated, smile-free vertical polyacrylamide gel separations of oligo and polynucleotides, nucleic acid sequencing, genotyping and polymorphic studies. Features and components included: The S2 runs a 31.0 x 38.5…
What is the size of H58 gel electrophoresis?
The H58 is a 5.7 cm x 8.3 cm horizontal format gel electrophoresis apparatus designed for rapid, high resolution separation of nucleic acids and proteins. It’s suitable for agarose gel electrophoresis procedures where buffer recirculation is not required. The H58 is a compact…
What is the principle of electrophoresis?
In electrophoresis, the substance that has to be separated is made to travel across a gel with a specific pore size using an electrical field. Also, one end of the gel has a positive charge, while the other end has a negative charge. The movement of the substance is based on its charge and mass.
