Casella VAPex™ Air Sampling Pumps

Casella Vapex Air Sampling Pumps provide low‑flow performance that R&D programs can trust during gas and vapor sampling. R&D labs often need to quantify volatile organic compounds from new materials, assess emissions during process trials, or validate exposure controls before scale‑up. In each case, precise flow control at low rates helps achieve target sample volumes, which supports accurate analysis and repeatable outcomes.

Vapex integrates with common sorbent tubes and badges used across analytical methods in environmental, materials, and occupational research. The pump’s control system helps maintain setpoints as back pressure changes, which can help reduce variability across replicates. Clear status indicators and data logging support audits, reporting, and peer review, while optional wireless features can streamline calibration checks and notes.

Key advantages for research and development:

• Precise Low‑Flow Control: Supports accurate sampling for gas and vapor studies using sorbent media.
• Quiet, Compact Design: Minimizes disruption in sensitive lab environments and test chambers.
• Robust Data Logging: Captures the context needed to compare results across trials and locations.
• Flexible Mounting Options: Supports personal and area sampling in labs and pilot spaces.
• Simple Calibration: Helps teams maintain consistency and traceability across studies.

Typical R&D applications include:

• VOC screening during material selection and formulation
• Emissions testing from adhesives, coatings, and sealants
• Off‑gassing studies for electronics and polymers
• Method development for gas‑phase contaminants in controlled chambers
• Process evaluation during pilot runs and engineering trials

Practical guidance for R&D teams:

• Select Appropriate Sorbents: Match target analytes and expected concentrations to the media.
• Plan Sample Duration: Estimate breakthrough volumes and environmental conditions when setting flow rates.
• Standardize Procedures: Use consistent calibration practices and document environmental parameters.
• Validate With Blanks and Duplicates: Incorporate quality checks to assess method performance.

Vapex helps R&D groups capture high‑quality vapor samples without adding complexity to the lab day. Its combination of stable low‑flow control, quiet operation, and data capture supports faster iteration and more confident comparisons across projects, sites, and collaborators.
