The PF-8000 Respirometer System

PF-4000 and PF-8000 Respirometers

RSA’s PF-4000 and PF-8000 (pictured above) 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
