Intended use
Principle
The Surface Air System (SAS) encompasses several models which use the same principle.
Air is aspirated at a fixed speed for a variable time through a cover which has been machined
with a series of specially designed small holes. The resulting laminar airflow is directed onto the
agar surface of a “contact plate” (or Petri dish) containing media suitable for the microbiological
examination to be performed. When the pre-set sampling cycle is completed, the plate is
removed and incubated. The organisms are then visible to the naked eye and can be counted in
order to assess the level of contamination.
The basic idea
The major points of the Surface Air System (SAS) are:
1 To use a simple and inexpensive “contact plate” (“SURFAIR PLATE”,
“RODAC”) for surface, hands or air control. These plates are very well
known and easily available and can be purchased ready poured with
different media.
2 To sample a known volume of air for a variable time to provide a
large range of sampling volumes.
3 To aspirate air in a laminar flow pattern with sufficient velocity to
impact organisms on an agar surface.
4 To accumulate data on the level of hygiene in each environment
so that fluctuations can be monitored.
5 To take advantage of advanced electronics for more reliable
results in different operating conditions.
6 To have the flexibility to choose between 55 mm contact plates
or 90 mm standard disposable Petri dishes.
7 To apply cGLP and cGMP to air sampling operations.
8 To organise sequential sampling to obtain a more representative
sample under actual operating conditions.

vwr.com | Instruction manual6
Models available
SAS SUPER ISO USB 100 and SAS SUPER ISO USB 180: Two instruments for two different
applications.
The two air samplers have the same performances with the only difference being in the rate of
air aspirated:
SAS SUPER ISO USB 100 = 100 litres of air per minute.
SAS SUPER ISO USB 180 = 180 litres of air per minute.
The SAS SUPER ISO USB 180 is appropriate for use in cleanrooms and other applications
demanding fast sampling times. In cleanrooms, for example, it is important to test larger volumes
of air, because microbial air contamination is very low. The SAS SUPER ISO USB 180 reduces the
time required to obtain a sample.
Both SAS SUPER ISO USB 100 and SAS SUPER ISO USB 180 are identified as “SAS
SUPER ISO USB”.

Preliminary inspection
The apparatus is subject to specific working tests before shipping and it is carefully packed to
avoid possible damages during transportation. However, a visible check should be carried out
as soon as possible to determine any transit damage. This must be reported immediately. The
following procedures should be followed to check that the unit is working properly.
The battery pack of the instrument must be charged for at least 5 hours before testing SAS
SUPER ISO USB 100 and SAS SUPER ISO USB 180.
After OK is pressed for at least two seconds, an automatic visual presentation appears (see visual
display presentation paragraph).
Press OK to start air sampling with the last cycle. The motor will run until the figures in the
brackets reach the same figure as displayed to the right and then it will stop. To stop the
run, press and .

Holder adjustment
Contact plate and the Petri dish holders can be adjusted (using a hex key) in case the
available plates are slightly different in diameter from the standard 55 mm contact plate
or 90 mm Petri dish.
Petri head adapter (optional)
An adapter is available in aluminium or stainless steel which allows the use of standard
90 mm Petri dishes with SAS for contact plates.
Filling 90 mm Petri dishes
We recommend filling standard 90 mm disposable Petri dishes with no more than 18 - 20
ml of agar to avoid the medium touching the inside surface of the aspirating head.
Tripod installation (optional)
The SAS SUPER ISO USB 100 and SAS SUPER ISO USB 180 can be fixed to a table/floor
tripod or a wall support. The screw thread connection is located underneath the unit,
between the two front feet.
Functions
