Introduction
The Tisch Environmental TE-BC251 is a wearable, multi-stage bioaerosol cyclone for collecting airborne biological particles for subsequent laboratory analysis. It is designed for personal and field sampling and connects to a commercially available personal air-sampling pump.
Key features
- Two-stage cyclonic separation with collection across three size ranges.
- Standard operating flow rate of 3.5 L/min.
- Collection compartments for particles above 1.8 µm, from 1.0–1.8 µm and below 1.0 µm.
- Wearable format for occupational, healthcare and environmental sampling applications.
- Can be used with an optional backpack or tripod configuration, subject to the selected setup.
Applications
- Bioaerosol and airborne microorganism research.
- Occupational-health and workplace exposure studies.
- Healthcare and indoor-environment sampling programmes.
- Environmental and infectious-disease research requiring laboratory analysis of collected samples.

What it solves
The TE-BC251 provides a wearable collection method for separating bioaerosol particles by size before laboratory analysis. It is intended for sampling workflows, not real-time pathogen identification or an automatic health-risk determination.
