CHAPTER I
BASIC PRODUCT INFORMATION
Based on our vertical laminar flow cabinet product line, our PCR cabinet has been designed specifically
for polymerase chain reaction (PCR) applications. The cabinet isolates critical steps in the PCR process
by providing a particulate-free work environment and can b
e operated effectively as “mini-environments”
in the laboratory. Vertical laminar flow cabinet offers proven protection for your sample and processes
where operator protection is not required. They are suitable for application which requires ISO Class 3 air
cleanliness within work zone as per ISO 14644-1 (equivalent to Class 1 per US Federal Standard 209E)
AIRFLOW PATTERN INSIDE THE CABINET
Room air is taken in from the top of the cabinet through a disposable pre-filter with 85% arrestance; this
serves to trap larger particles and increase the life of the main filter. Air is forced evenly across an
HEPA/ULPA-filtered vertical laminar flow air stream within the cabinet; the result is a stream of clean
laminar air within the work zone of the cabinet; this dilutes and flushes all airborne contaminants from the
interior. A nominal filter face velocity of 0.45 m/s or 90fpm ensures that there is sufficient number of air
changes within the enclosed are of the cabinet in order to maintain cleanliness. The purified air travels
across the internal work zone of the cabinet in a vertical, unidirectional stream and leaves the main work
chamber across the entire open front of the cabinet.
