Strathtox is an integrated desktop respirometer comprising the following sub-systems:
Temperature controlled Circulating Waterbath This is used to maintain the activated sludge at constant temperature during a respirometry run. A six position magnetic stirrer is located beneath the bath. The six 20ml respirometer cells are located in a rack, for easy removal at the end of a run.
Activated Sludge Temperature Controlled Containment A flask provides aeration and containment of approximately 600ml of AS that can also be spilt for Nitrification testing.
Oxygen Electrodes These high precision electrodes are housed in electrode holders for easy insertion into the respirometer cells. They require little maintenance, other than occasional membrane changes.
Oxygen Interface The six oxygen electrodes are connected to this unit, which transmits the digital signals to the computer software.
The easy-to-use Windows software comprises 5 different tests. Each test program has a similar basic structure compromising four stages: Setup; Recording; Analysis; Report.
