THE BUYER'S GUIDE / SELECTION
Selecting the right bioaerosol sampler requires matching the device's operating mode, run time, flow rate, and particle collection range to your specific monitoring scenario. This guide walks through the key purchase criteria — sampling continuity, deployment environment, downstream analysis compatibility, and ease of operation — and maps them to the confirmed specifications of SUZHOU CHANGHE BIOTECH CO., LTD's CA-1-300 and LCA-1-300 models, so procurement teams can identify which configuration fits their site before requesting a quotation.
Sampling continuity and run time: spot sampling (1–15 min, battery-portable) versus continuous unattended monitoring (up to 48 h with automatic solution replenishment) determines which model is appropriate for the monitoring schedule and operator availability.
Particle collection range and deployment environment: both models use wet-cyclone technology capturing ≥ 0.8 μm particles in a liquid concentrate compatible with qPCR and sequencing; field deployments requiring weather tolerance and autonomous operation narrow the choice to the LCA-1-300.
A bioaerosol sampler is only as useful as its match to the monitoring task. Two facilities may both need airborne pathogen data, yet require completely different devices: a food-manufacturing plant running a one-time audit demands a different tool than a livestock barn that needs round-the-clock surveillance. Clarifying four core criteria — sampling continuity, particle capture range, downstream analysis method, and deployment conditions — before you compare models prevents costly mismatches.
The most immediate decision is whether you need spot sampling or continuous, unattended monitoring.
Both wet-cyclone (impact) samplers described in this guide capture particles ≥ 0.8 μm, which covers the size range of bacteria clusters, fungal spores, and most respiratory virus-laden droplet nuclei. Confirm that this lower bound is consistent with the pathogens you are targeting. If your protocol specifies a different cut-point, request updated technical documentation before ordering.
Wet-cyclone technology concentrates collected material into a liquid phase, which is directly compatible with downstream qPCR or sequencing workflows — a meaningful advantage over impactor-based dry collection when molecular analysis is the endpoint.
Verify that the collection solution volume and format match your laboratory's extraction and amplification protocol. The wet-cyclone design delivers a liquid concentrate, making it straightforward to transfer to PCR tubes or sequencing prep kits. If your lab uses a culture-based method, discuss collection solution chemistry with the manufacturer before specifying a model.
Consider where the sampler will be placed:
Evaluate the operator-hour cost alongside hardware cost. A sampler that requires frequent manual liquid replenishment may be adequate for short runs but becomes a bottleneck in continuous monitoring programs. Automatic solution replenishment significantly lowers operational labor and reduces the risk of sample chain interruption.
The CA-1-300 uses wet-cyclone operation and covers a wide range of venues: animal husbandry, pharmaceutical manufacturing, food production, laboratories, hospitals, exhibition halls, shopping malls, restaurants, offices, rail transit, classrooms, stadiums, and ambient outdoor air.
| Parameter | Specification |
|---|---|
| Model | CA-1-300 |
| Air Flow Rate | Low 150 L/min · High 300 L/min |
| Running Time | 1–15 min |
| Collected Particle Sizes | ≥ 0.8 μm |
| Collection Efficiency | D50 |
Design highlights: lightweight and battery-powered for portability; user-friendly interface for easier field operation; validated for qPCR and sequencing analysis; compatible with livestock, zoonotic, and human-related virus targets.
Best fit: buyers who need a portable unit for spot checks across multiple locations, or who require a device that can be redeployed by a single operator.
The LCA-1-300 extends the same wet-cyclone (impact method) platform to support up to 48 hours of continuous, unattended sampling. The sampler actively captures bioaerosol components in the surrounding air and concentrates them in a special aerosol sampling solution under high-speed airflow. Automatic solution replenishment eliminates the need for frequent manual replacement, making it suitable for deployments where operators cannot be present around the clock.
