When labs tell me they’re juggling culture plates, impingers, and awkward pumps, I point them to the Bioaerosol Sampler. It’s the CA-1-300 wet-cyclone model out of Shanghai, and—honestly—it hits a sweet spot between rugged field gear and lab-grade capture efficiency. Wet-cyclone isn’t new, but the way this unit balances flow stability, viability protection, and portability is, well, unusually practical.
Demand for environmental surveillance keeps climbing: hospitals tracing HAIs, food plants proving sanitation, transit hubs watching seasonal spikes. The trend is clear—faster, defensible bioaerosol data, with fewer moving parts. And, to be honest, fewer headaches. A wet-cyclone Bioaerosol Sampler supports viable organisms better than dry filters in many conditions, which is a real-world edge when downstream culture or qPCR is critical.
The CA-1-300 pulls air at a controlled high flow into a cyclone chamber where particles spiral into a liquid film—usually sterile PBS or collection buffer (≈10–20 mL typical). That liquid becomes your sample for culture, PCR, or immunoassay. Materials are corrosion-resistant (anodized aluminum housing, chemical-resistant seals, lab-grade tubing). Service life? The cyclone body is engineered for multi‑year duty (≈5+ years with routine cleaning), and fans/pumps are rated for around 10,000 h in real-world use.
Testing is typically aligned to ISO 14698 biocontamination control, NIOSH bioaerosol methods, and internal QA against flow accuracy (±5% target), noise, and microbial viability checks with surrogate organisms.
| Model | CA-1-300 Bioaerosol Sampler |
| Sampling principle | Wet-cyclone (viability-preserving collection) |
| Flow rate | ≈300 L/min (real-world use may vary ±5%) |
| Particle capture | Down to ≈0.5–1 µm (method-dependent) |
| Collection liquid | PBS / buffer, ≈10–20 mL |
| Noise | ≈60–65 dB at 1 m |
| Power/Battery | AC + optional battery pack (≈4–6 h) |
| Dimensions/Weight | Portable frame; field-deployable (around 6–8 kg) |
Many customers say the liquid output reduces prep time. It seems that viability is better than filters in dry climates, which tracks with the literature.
| Feature | CA-1-300 (wet-cyclone) | Vendor A (impinger) | Vendor B (filter-based) |
|---|---|---|---|
| Flow | ≈300 L/min | ≈12–20 L/min | ≈2–100 L/min |
| Viability | High (liquid capture) | Moderate–High | Variable; desiccation risk |
| Setup time | Low | Moderate | Low–Moderate |
| Consumables | Buffer only | Glassware + buffer | Filters (recurring) |
Options include alternate cyclone liners, heated inlets for cold sites, barcode sample tracking, and Bluetooth data export. Typical certifications: ISO 9001 manufacturing, CE, RoHS; designed to align with ISO 14698, ISO 16000 series, and NIOSH bioaerosol methods (0800/0801). Site address: FLOOR 7, NO.1588 HUHANG ROAD, SHANGHAI, CHINA.
Maintenance is basic: rinse cyclone with sterile water, periodic 70% IPA wipe, quarterly seals check. Keep a log for service intervals—small habit, big payoff.
If you need defensible air microbiology without wrestling a lab bench into the hallway, a wet-cyclone Bioaerosol Sampler like the CA-1-300 is—actually—one of the saner picks right now.
