Laboratory evaporator Cat#-NT

nitrogensolventwith dry block

Optimized for PFAS Analysis and Water Sample Concentration The N-EVAP is a high-capacity, nitrogen blowdown evaporator specifically well-suited for PFAS analysis and environmental water testing workflows. Designed to meet the stringent sample preparation requirements of laboratories focused on trace contaminant detection, this evaporator delivers consistent, low-contamination concentration of aqueous samples. Each of the 12 or 24 positions features independently adjustable nitrogen flow, allowing for precise control over evaporation rates—critical when working with PFAS compounds to avoid cross-contamination or loss of volatile analytes. The system’s gentle, heated water bath ensures even temperature distribution, promoting efficient yet careful evaporation to dryness or a desired final volume. A standout choice for environmental labs processing multiple water samples simultaneously, the N-EVAP supports test tubes with diameters from 10–30 mm in its standard configuration. For laboratories handling larger volumes, an optional large tube holder accommodates vials up to 70 mm in diameter. For smaller applications, an optional holder is available for vials ranging from 5–16 mm. The rotating circular design provides easy access to all sample positions from the front of the unit, while the robust, chrome-plated brass needle valves allow for uniform, precise nitrogen delivery—minimizing waste and ensuring reproducible results. Trusted by analytical labs worldwide, the N-EVAP offers a clean, efficient, and reliable solution for high-throughput PFAS and water testing sample preparation.
