Removal of the Agar Strip

• Unscrew the protection cap and remove the
rotor from the magnetic flange.
• To remove the agar strip pull out by the strip
holder. Place the agar strip back into the
protective packaging with the agar surface facing

protective foil).
• Seal the protective packaging by using a cover
slide provided with the agar strips to avoid drying
of the agar during incubation.
NOTE
• It is recommended to label the agar strips with
most important parameters to avoid mistakes
during analysis.
• For incubation of the agar strips an incubation
rack is available (Article No. 1.44249.0001).

Incubation and Analysis

Counting of colonies is performed after an appro-
priate incubation period with the agar strip still
placed within its protective packaging. The number
of colony forming units (CFU) on the entire agar
strip is analyzed in relation to the air volume sam-
pled (in liters).
The calculation of CFU per cubic meter (m
performed according to the following formula:
CFU per agar strip
CFU/m³ =
Selected sample volume
(liters)
