Labconco's Purifier® Filtered PCR Enclosures provide a controlled environment to perform polymerase chain reaction experiments. The PCR has been used in such diverse fields as zoology, anthropology and criminology. The polymerase chain reaction is a process that can be used to exponentially multiply minute amounts of DNA. In fact, PCR is used to make millions of exact copies of DNA from a biological sample. DNA amplification with PCR allows DNA analysis on biological samples as small as a few skin cells. The ability of PCR to amplify such tiny quantities of DNA enables even highly degraded samples to be analyzed. Some examples of DNA uses for forensic identification include identifying potential suspects whose DNA may match evidence left at crime scenes, exonerating persons wrongly accused of crimes, identify crime and catastrophe victims, and establish paternity and other family relationships.
ISO Class 5 air is constantly projected vertically down over the work area, minimizing the risk of cross contamination. During operation, room air is drawn through a pre-filter in the top of the cabinet to trap large particles. Then, the air flows through a 99.99% efficient HEPA filter and is projected over the work area. HEPA-filtered air prevents contaminants from entering the work area and provides a particulate-free environment.
A digital timer provides UV light exposure continuously or in user-selected increments of 5, 10, 15, 30, 60, 120, or 240 minutes to deactivate DNA and RNA contaminants. When the time expires, the UV light automatically switches off in preparation for the next experiment. Bi-fold doors close the sash opening while the UV light is on and prevent contaminants from entering when the enclosure is not in use. The Purifier Filtered PCR Enclosures are available in 2-, 3- and 4-foot widths. An airflow monitor is optional.
