Technical Data

Sampling principle: Microbial air sampler of
®
the RCS series employ the impaction principle,
whereby the air stream enters the rotor at
the front of the instrument and the airborne
microbes are separated onto the agar strip
by centrifugal force.
Measurement range: 1-1999 liters (recom-
mended measurement range 10-1000 liters)
Air flow-rate: approx. 50 L/min
Instrument precision: ± 5%
Sample volume: 7 volumes in memory in
ascending order of 10, 20, 50, 100, 200, 500
and 1000 liters. 3 positions in memory, individual
selectable from 1 to 1999 liters. The accuracy
of sampling volume is achieved through cali-
bration.
Rotor speed: approx. 6100 rpm
Maximum allowable axial force on rotor
shaft: 30 Newtons
Power supply: Rapid charging 7.2 V nickel cad-
mium battery (charging time 1 hour)
Automatic power-off: The instrument
switches itself off automatically after
8 minutes
Materials:
• Housing: polycarbonate; resistant to 70%
ethanol
• Rotor: anodized aluminium; autoclavable
• Protection cap: stainless steel; autoclavable
