  • PF-4000 and PF-8000 Pulse-Flow Respirometers

    RSAs PF-4000 and PF-8000 Pulse-Flow respirometers are designed specifically to measure oxygen uptake for aerobic biological reactions and gas production from anaerobic and anoxic biological reactions. Modular system design allows easy expansion. The 8-position PF-8000 units can be expanded easily to 16 and 24-position units. The 4-position PF-4000 units can be expanded to an 8-position system.

    A few of the applications of the pulse-flow respirometers are:

    Biodegradation Assessments
    Activated Sludge Respiration (ASR) Tests
    OUR Fingerprinting (OUR Respirograms)
    Biomass Activity Tests
    Extant Kinetic Measurements
    Performance Evaluations
    Toxicity Assessments
    Short-Term BOD Measurements
