Cole-Parmer Global Water WS700R Refrigerated Wastewater Sampler  DFS Item

Manufacturer:  Cole-Parmer 9924320

This economical refrigerated sampler allows you to take individual time-weighted composite samples or full-bottle discrete grab samples in the supplied 2 gallon polyethylene sample bottle. Sample size control allows individual time-weighted samples or full-bottle discrete samples. Sample interval control allows you to set the time between individual composite samples or enable the external trigger mode. Start delay timer allows multiple units to be set for concurrent sampling or to delay the start of sampling after an event for a more representative sample. Automatic 15 second back flush cycle clears debris from the intake strainer and empties the sample hose so the next composite sample is not contaminated. An external pulse type flow meter can control the sample interval for true flow proportional water sampling. The sample bottle is equipped with a float switch that automatically turns off the pump when the bottle is full.
