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 100 and
SAS SUPER ISO 180.
After the screen is touched for at least two seconds, an automatic visual presentation appears (see visual display
presentation paragraph).
Press START on the screen 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.

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)
