Air Sampling Pumps

Advancing research depends on reproducible sampling that captures airborne contaminants consistently across trials, instruments, and environments. Casella air sampling pumps from TSI are designed to support rigorous R&D workflows by delivering precise, consistent flow control across personal, low-flow, and high-volume applications.

Whether you are refining a sampling method, executing exposure simulations, or characterizing emissions from new materials, pump selection starts with the protocol. Define target analytes, media, flow range, and sampling duration, then match the pump to the requirement:

• Apex2 personal pumps: Support particulate and mixed contaminant sampling for bench-to-field studies, human factors evaluations, and exposure simulations.
• VAPex air sampling pumps: Purpose-built for low-flow sampling of vapors and gases during method development, compound screening, and sorbent tube studies.
• Vortex3 high-flow pumps: Provide high-volume area sampling capability for asbestos and other hazardous materials, as well as chamber or enclosure studies that need elevated flow.

Consistent flow helps maintain sample integrity as back pressure shifts across media, tubing, and environmental conditions. This stability supports standardization across replicates, improves comparability between experimental arms, and helps reduce sources of variability that can complicate analysis. For R&D teams balancing precision with throughput, a pump platform that sustains target flow over long runs is a practical asset.

R&D environments range from controlled laboratories to pilot sites and outdoor test locations. Casella pumps are designed for rugged use, making lab-to-field transitions straightforward. This versatility helps teams deploy a single portfolio across different stages of development without rebuilding the sampling approach for each site.

Typical research applications include:

• Validating sampling trains and media for novel or mixed aerosol challenges.
• Measuring emissions, off-gassing, or VOC profiles from new materials and devices using low-flow vapor methods.
• Characterizing aerosol behavior in chambers, ducts, or enclosures with high-volume area sampling.
• Evaluating engineering controls and prototypes by comparing baseline and modified conditions.

Method fidelity is central to credible research. By aligning the pump to recognized methods and protocol requirements, teams can design sampling that supports defensible conclusions and smooth technology transfer. Apex2 supports personal exposure-style protocols. VAPex meets low-flow needs common in vapor and gas studies. Vortex3 addresses high-flow applications where volume and time are critical.

Practical considerations matter as well. Set up pumps according to the sampling plan, verify pre- and post-flow, record environmental conditions, and document any deviations. These steps, supported by stable pump performance, help sustain data quality across replicates and sites.

From early feasibility to validation and field trials, Casella air sampling pumps provide the flow control and application breadth that R&D programs need. Pair the right pump with the right method to strengthen repeatability, accelerate study execution, and support publication-quality results — without adding complexity to your protocol.
