We receive a lot of questions about Vacuum vs Peristaltic Portable Samplers for Water, Wastewater, Stormwater and Runoff Monitoring. We're looking today at three of the leading providers of water samplers and sampling equipment. These water samplers use different sampling technologies and pumps to get the job done: ISCO 6712 vs Campbell Scientific vs Hach Sigma SD900. See the full comparison table of Peristaltic Vs Vacuum Portable Samplers. Portable water samplers use either peristaltic pump or vacuum pump technology to obtain the liquid samples. Both portable sampler pump technologies are designed to quickly move most fluids from the source into the water sampler. Let's take a closer look at Portable Vacuum Samplers vs Portable Peristaltic Samplers So what do you see as the main differences between vacuum based samplers and peristaltic samplers?
