Portable Microbial Air Sampler, 100 L/min
Portable microprocessor-controlled air sampler for biological particle collection at 100 L/min flow rate with battery or AC operation.
The Biological Air Sampler is a portable microprocessor-controlled instrument designed for collection and assessment of airborne biological particles in research and monitoring environments. The system employs a low-noise pump to draw air samples at 100 L/min ±5% through collection media, enabling quantitative analysis of microbial contamination levels in various settings.
Built with anodized aluminum construction for durability, the unit features dual power operation through rechargeable 12V/3000mAh battery or AC mains supply. The compact design (120×200×340mm) and 6-8 hour battery operation facilitate field sampling campaigns and continuous monitoring applications where AC power may be unavailable.
How It Works
The Biological Air Sampler operates on the principle of active air sampling, where a microprocessor-controlled pump draws ambient air through the sampling system at a calibrated flow rate of 100 L/min ±5%. The controlled airflow ensures consistent sample collection volumes essential for quantitative analysis.
Air is drawn through collection media (typically agar plates, impaction surfaces, or filtration substrates) where biological particles are captured based on their size and inertial properties. The low-noise pump design minimizes vibration and operational interference while maintaining precise flow control through integrated microprocessor regulation.
Collected samples can then be processed using standard microbiological techniques including culture-based enumeration, molecular analysis, or microscopic examination depending on the specific research objectives and target organisms.

Practical Tips
Verify flow rate accuracy using a certified external flow meter before critical sampling campaigns, particularly after transport or extended storage.
Why: Flow rate precision directly affects sample volume calculations and quantitative analysis accuracy.
Clean and inspect pump intake regularly for debris or biological buildup that could affect flow characteristics.
Why: Obstructions can reduce sampling efficiency and compromise flow rate stability during collection periods.
Position the sampler at breathing zone height (1.5m) and away from direct air currents or HVAC outlets when assessing human exposure risks.
Why: Proper positioning ensures representative samples of the air actually inhaled by occupants in the environment.
Monitor battery voltage during extended sampling runs and maintain spare charged batteries for critical field deployments.
Why: Battery depletion during sampling can result in incomplete collection and compromised data quality.
Record ambient temperature, humidity, and wind conditions during sampling as these factors affect particle dispersion and collection efficiency.
Why: Environmental conditions influence microbial viability and distribution, affecting interpretation of sampling results.
Use appropriate PPE and follow biosafety protocols when sampling in potentially contaminated environments or handling collected samples.
Why: Biological air sampling may concentrate pathogenic organisms requiring containment and handling precautions.
Check for pump seal integrity if flow rate deviates from specification, as worn seals can cause pressure losses.
Why: Seal degradation is a common cause of flow rate drift and reduced sampling performance over time.
