Preliminary inspection

The apparatus is subject to specific quality tests before shipment and is carefully packed to avoid possible damage
during transit. However, a visible check should be carried out as soon as possible to determine any 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 14 hours before running the test.
After the 'ON/OFF' button is pressed an automatic visual presentation will be displayed.

Holder adjustment

The contact plate and Petri dish holders can be adjusted (using a screw driver) in case the available plates is 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.

90 mm Petri dish filling

We recommend you fill the standard 90 mm disposable Petri dish 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 can be fixed to a table, floor tripod or wall support. The screw thread connection is located under the unit,
between the two front feet.
When not in use, the connection cavity is protected by a metal screw insert.
