The portable Spiral Biotech MicroBio Air Sampler monitors air quality by collecting airborne bioaerosol contaminants on Petri dishes in both indoor and outdoor environments. The MicroBio utilizes simple and inexpensive contact plates for air quality control. The resulting quantitative data correlates directly to the volume of air sampled in the environment and can be easily evaluated over time. Available for 55mm and 100mm plates, the MicroBio is perfect for any situation where air sampling is required.

Features:
· Adjustable sampling volume from 25 L to1000 L
· User-programmed frequently used volumes
· Programmable and time-delayed operation (15 to 300 seconds)
· Lightweight (650 g) and portable
· Rechargeable NiMH batteries
· Quiet operation
· Easy-to-read alpha-numeric display
· Microprocessor controlled

How it works:
Air is aspirated through a removable metal head, containing a series of 1 mm holes, at a rate of 100 liters/min. The laminar airflow created by this design impels microorganisms onto the agar surface. Once incubated, the visible colonies can be counted. The count, along with volume of air sampled, is used to calculate the number of microorganisms per cubic meter of air (CFU/m3).
