Century 3000-CVE-16 Indoor Refrigerated Composite/ Sequential Vacuum Wastewater Sampler                           

Wide range of bottle configurations and QCEC reliability

Century 3000-CVE-16Built tough for tough duty, the Century 3000-CVE-16 is our refrigerated vacuum wastewater sampler. It relies on proven vacuum pump technology to deliver high sample integrity and reliable performance. The vacuum pump exceeds EPA transport velocity requirements and generates a stronger purge. The maximum vertical lift is 23 feet on a standard unit, and 28 feet is available as an option. A two year warranty is standard.​
