Which volume of air should be aspirated?
The number of collected C.F.U. on the agar surface, after incubation, should be easily countable (up to 200 C.F.U.).
Therefore the most common volumes are 100-300 litres in normal environments (high contamination) and 1000 litres in Clean Room (low contamination).
Which volume of agar medium in each culture plate?
14/16 ml in 55 mm Contact plate
24/30 ml in 90 mm Petri dish.
What is the advantage of battery charger by induction vs traditional cable?
The induction is by contact and therefore there are no connections and cable.
Why “Interval sampling”?
To obtain a representative sample “in operation” conditions.
More than one air sample, on the same culture plate, in sequential order.
Why “Remote Control”?
Typically it is used in Clean Rooms from the outside of the core to reduce risk of contamination from the operator.
