Analyze activated sludge processes using the Thermo Scientific™ Nalgene™ Settlometer Kit. This kit is an all-plastic tool for wastewater treatment plant operators and is a cost-effective alternative to the glass equivalent. Settlometers and centrifuges are used to monitor sludge quality when analyzing activated sludge processes. The 2L can is lightweight, clear, highly impact resistant and has an easy to read white scale. The stirring paddle can stir smoothly without scratching the tank wall. Tubes fit benchtop centrifuges up to 6000 xg without liners or adapters.
