Intended use
Principle
The Surface Air System (SAS) encompasses several models which use the same principle. Air is aspirated at a
fixed speed for variable time through a head which has been machined with a series of small holes of a special
design. The resulting laminar airflow is directed onto the agar surface of a “RODAC Plate” (or a Petri dish)
containing medium for microbiological analysis.
When the selected sampling cycle is completed, the plate is removed and incubated. The organisms are then visible
to the naked eye and can be counted for the assessment of contamination levels.
ENGLISH
8
The basic idea
The key features 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. They can be purchased ready poured with
different media.
2. To sample a known volume of air for a variable time to provide a range of sampling volumes.
3. To aspirate air in a laminar flow pattern with sufficient velocity to impact organisms onto 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 Petri dishes.
7. To organise sequential sampling to obtain a more representative sample under actual operating conditions.

CALIBRATION DUE

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.
Functions
Operations
Press the ‘ON/OFF’ switch (black button) to switch on the unit.
The ‘ON/OFF’ switch (black button) must be pushed twice to switch the unit on if the automatic switch-off timer was
used previously.
Press ‘CLEAR’ at any time to return to the initial ‘START FOR’ main screen.
The air sampler is provided with eight fixed air volumes (‘Standard Mode’) stored in the memory and eight
programmable air volumes (‘USER MODE’) selectable by the operator.
Volume selection is made by pressing the “▲” or “▼” arrows when the programme is in the relevant sub menu.

Verwendungszweck
Funktionsprinzip
Das Surface Air System (SAS, Oberflächen-Luft-System) umfasst mehrere Modelle, die auf dem gleichen
Funktionsprinzip beruhen. Luft wird mit einer festen Geschwindigkeit über einen variablen Zeitraum durch einen
Entnahmekopf angesaugt, der eine Reihe von kleinen Bohrungen mit einer speziellen Konstruktion aufweist. Die
resultierende Laminarströmung wird auf die Agar-Oberfläche einer RODAC-Platte (oder Petrischale) gelenkt, die ein
Nährmedium für die mikrobiologische Untersuchung enthält.
Wenn der gewählte Probenahmezyklus abgeschlossen ist, wird die Platte entfernt und inkubiert. Die Organismen
sind dann mit bloßem Auge erkennbar und können zur Beurteilung des Kontaminationsgrads gezählt werden.
DEUTSCH
28
Grundkonzept
Die Hauptmerkmale des Surface Air Systems (SAS) sind folgende:
8. Verwendung einer einfachen und preisgünstigen „Abklatschplatte“ („SURFAIR PLATE“, „RODAC“) für
Oberflächen-, Hand- oder Luftsteuerung. Diese gängigen und problemlos erhältlichen Platten können mit
unterschiedlichen Nährmedien vorgefüllt erworben werden.
9. Entnahme eines bekannten Luftvolumens über einen variablen Zeitraum zur Bereitstellung eines
Spektrums an Probenvolumen.
10. Ansaugung von Luft in einer Laminarströmungsstruktur mit ausreichender Geschwindigkeit, um
Organismen auf eine Agar-Oberfläche zu schießen.
11. Sammlung von Daten zum Hygieneniveau in jeder Umgebung, um die Fluktuationen zu überwachen.
12. Nutzung hochentwickelter Elektronik für zuverlässigere Ergebnisse bei unterschiedlichen
Betriebsbedingungen.
13. Flexibilität der Auswahl zwischen 55-mm-Abklatschplatten und 90-mm-Standard-Petrischalen.
14. Organisation einer sequenziellen Probenahme für repräsentativere Proben unter tatsächlichen
Betriebsbedingungen.
Kurzanleitung
Kurzanleitung für SAS Isolator
Der Luftstrom wird bei jedem Einschalten des Geräts nach der automatischen Darstellungsabfolge angezeigt.
Betriebsschalter „ON/OFF“ drücken.
Die Taste „START“ drücken, um das gleiche Luftvolumen wie beim letzten Probenahmezyklus zu entnehmen.
Zur Änderung des Luftvolumens mit Hilfe der Pfeiltasten „Standard Mode“ aus dem Menü wählen.
Für Änderungen der Einstellungen die Bedienungsanleitung heranziehen.
Zur Bestätigung der Auswahl „ENTER“ drücken.
Menüs mit Hilfe der Pfeiltasten auswählen, um weitere voreingestellte Parameter zu ändern:
STANDARD MODE
USER MODE
PROGRAM MODE
DELAY MODE
MULTI MODE
UTILITY MODE
„ENTER“ drücken, um das Untermenü des gewählten Parameters aufzurufen.
Hinweise zum Ändern der Einstellungen finden Sie in der Bedienungsanleitung.
Am Ende der Probenahme den Betriebsschalter „ON/OFF“ drücken.
Jedes Mal „CLEAR“ drücken, wenn eine Aktion abgebrochen werden soll. Das Gerät wird dann auf seine
ursprüngliche Konfiguration zurückgesetzt.

Erste Inspektion
Das Gerät wird vor der Auslieferung spezifischen Qualitätstests unterzogen und sorgfältig verpackt, um einer
möglichen Beschädigung während des Transports vorzubeugen. Es sollte jedoch so bald wie möglich eine
Sichtprüfung durchgeführt werden, um etwaige Schäden festzustellen. Diese sind unverzüglich zu melden. Die
folgenden Arbeitsschritte sind durchzuführen, um zu überprüfen, ob das Gerät korrekt funktioniert.
Vor Durchführung des Tests ist der Akku des Geräts mindestens 14 Stunden lang aufzuladen.
Nach dem Drücken des Betriebsschalters „ON/OFF“ erscheint eine automatische Anzeigeabfolge.
Halteranpassung
Die Abklatschplatten- und Petrischalenhalter können verstellt werden (mit einem Schraubendreher) falls sich der
Durchmesser der verfügbaren Platten geringfügig von der 55-mm-Standard-Abklatschplatte oder
90-mm-Petrischale unterscheidet.
Petrischalenadapter (optional)
Ein Adapter aus Aluminium oder Edelstahl ist erhältlich, der die Verwendung von 90-mm-Standard-Petrischalen mit
dem SAS für Abklatschplatten ermöglicht.
Befüllen von 90-mm-Petrischalen
Wir empfehlen, die 90-mm-Standard-Petrischale für den Einmalgebrauch mit nicht mehr als 18–20 ml Agar zu
befüllen, um zu verhindern, dass das Nährmedium mit der Innenfläche des Ansaugkopfs in Kontakt kommt.
Installation des Stativs (optional)
Das SAS kann an einem Tisch-/Bodenstativ oder einer Wandhalterung befestigt werden. Das Schraubgewinde
befindet sich unten am Gerät, zwischen den beiden vorderen Standfüßen.
Wenn sie nicht verwendet wird, wird die Gewindeöffnung durch eine Metallschraube geschützt.
