| Long-term tests have shown that the size
spectrum of particles captured indicated that the Cyclone
was more efficient at sampling paucimicronic particles
(19.9% of total particles below 2.5 µm compared with
9.5% using a standard impaction system). Spores are
collected and retained in a viable condition, the
eppendorf vial can be capped and refrigerated for
subsequent evaluation.
Construction and Equipment Details
A self-contained instrument with built-in mains
charger and mains voltage selector available for 120v or
240v ac. The power unit is fitted with Nickel Cadmium
batteries maintaining an air throughput up to 20 litres
per minute. The pre-set timer on the front panel will
allow 99 minutes of running time and an audible alarm
will sound when the sampling time is complete. A neon
indicator shows when the system is functioning. The
cyclone unit is a precision item fully machined from hard
alloy material, natural anodised to prevent corrosion.
