      In the world of environmental testing, many labs encounter extremely dirty samples. For example, EPA Method 1664B is the protocol for extracting oil and grease from wastewater samples. More often than not, these types of samples are really dirty, requiring loads of pre-filters, glass wool, and filter aid in order to get the entire liter of water through the disk. Well, there is!
