Hey I am currently working in a biopharmacuetical lab which requires daily wfi sampling. Currently we Collect 250 ml for the microbial test, 125 for LAL and 40 for TOC. I am responsible for testing the 250 ml microbial water. As of right now we filter 100ml onto a 2um filter and place it onto TSA and MacConkey Agar. Does anyone know of a more cost effective means to do daily wfi sampling?
