Polymerase chain
reaction1 (PCR) is a
simple and inexpensive
technique to make
multiple copies of a
targeted nucleotide
sequence from a DNA
sample, and to amplify
sequences from small
samples. This technique
is widely used in genetics
laboratories that work
with DNA and RNA.
Because PCR amplification
is extremely sensitive
to contamination,
prevention of contamination
requires good
laboratory practices
to minimize external or
cross-contamination
during reagent
preparation, sample
preparation and
The Purair PCR laminar flow cabinet
employs the Air Science Multiplex
HEPA filtration technology to create a
safe, energy-efficient contaminant-free
environment. It is ideally suited for use
with non-hazardous contaminants
and when flexible access to the instrumentation
in the cabinet is required.
1 Polymerase chain reaction (PCR) is a patented process owned by Hoffman La Roche.
Applications
These cabinets are
intended for use in nonhazardous
applications
where biological or
biohazard byproducts
are not generated and
user protection is not
required.

PRODUCT FEATURES:
A. Task Lighting: Fluorescent cabinet lamp located away from laminar flow area.
B. Ultraviolet Lighting: Built-in ultraviolet lamp with timer
permits decontamination between PCR cycles. Includes
a double-flap safety cover of 0.2" (5 mm) UV absorbing
254 nm beta radiation resistant polycarbonate; provides
superior operator protection while allowing easy access
to the work zone. Timer can be set over range of 0 to 60
minutes or set to HOLD.
C. Comfort: Ergonomically angled front improves reach and user comfort.
D. Decontamination Shelf: Mounted on the back wall
is proximate to the UV lamp for maximum exposure.
E. Filter: Camfil Farr main HEPA filter with 99.99% efficiency
for 0.3 micron particulates. The pre-filter can be changed
while the unit is operating to prevent operator exposure
to chemical vapors.
F. Pass Through Ports: Convenient rear-wall pass through ports for safe routing of instrument cords, cables and leads.
G. Double-Hinged Self-Locking Front Sash: With overlap closed, the cabinet sash protects the operator with 100 fpm airflow. The sash is easy to open and latch.
H. Fan: High-performance ebmpapst centrifugal fan.
I. Stand: Optional base stand converts to mobile cart with optional locking casters.
J. Work Surface: Large polypropylene work surface, white or black standard, with optional stainless steel work surface available.
K. Filter Door Key: Prevents unauthorized removal
or accidental exposure to dirty filters.
L. Magnetic Door Latch: Safety interlock prevents accidental operator exposure when door is opened.
OTHER FEATURES:
360 Degree Visibility: Clear back and side panels
allow ambient illumination into the chamber and provide users with an unobstructed view of its contents.
Standards Compliant: Performance specifications and construction meet or exceed OSHA, ANSI and relevant international standards to assure operator safety.
Construction: All models are available in either metal or polypropylene construction, specify metal or polypropylene when ordering. Available in 120V, 60Hz or 220V, 50Hz models.
Steel Support Frame: The chemical resistant epoxy
coated steel frame adds mechanical strength. Optional
all polypropylene construction is available if desired.
The integrated control panel features an On/Off switch for the fan, light and UV lamp timer.

PURAIR® PCR AIRFLOW PATTERN
Purair® PCR-36 shown with Multiplex filtration system.
Room air enters from the top of the cabinet through the disposable pre-filter where larger particles are trapped, increasing the service life of the main HEPA filter.
Air is forced evenly across the HEPA filter to deliver a flow of pure, uniform air within the work zone to dilute and flush airborne contaminants from the work area.
A nominal filter face velocity of 0.45 m/s (90 fpm) ensures that there is sufficient number of air changes within the work zone to eliminate cross-contamination and to maintain optimum cleanliness.
Purified air travels across the work zone to the work surface in a vertical, unidirectional downflow stream, and then exits the work zone across the open cabinet front area of the cabinet.
A. The main filter is easy to replace; no tools required. The filter clamps tightly against the filter gasket to prevent filter bypass and to maintain filter integrity.
HEPA Filtration
Air Science uses long-life
Camfil Farr HEPA filters without
aluminum separators to
increase filter efficiency, minimize
the potential for leakage
and increase filter life.
Energy-Saving Blower System
Purair PCR cabinets incorporate
energy-efficient ebmpapst
permanently lubricated direct
drive centrifugal blowers for
maximum operational savings,
low noise and minimal vibration.
Face Velocity
Purair® PCR cabinets maintain a 0.45 m/s or 90 fpm air flow velocity, measured 6/150mm from the filter face, with a uniformity of +/- 20% across the filter face. This face velocity is in compliance with USA and international standards for safety and performance.
