Contrate fecal filters are especially useful when used in conjunction with swing arm centrifuges for fecal exams. The filter is designed to seat on top of conical test tubes. It is used to filter out particals and debris from fecal solution after the floatation solution has been mixed with the sample. The contrate fecal filter helps eliminate messy spills and is a good substitute for gauze sponges or tea bag strainers. 5/pkg.
