Q. We need to remove perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS) from laboratory glassware and stainless steel. Since they are inorganic residues, we’re using acidic cleaners, but are not finding them as effective as we expected. Any recommendations?
A. PFOS and PFOA are polar, anionic surfactants. They will best be cleaned by a high-emulsifying, anionic-surfactant-containing cleaner that can make mixed micelles to efficiently remove these residues from surfaces….
Q. is there any industry guidance on triple rinsing…any literature that you know of that this is the accepted standard for manual cleaning that you could provide me?
A. To our knowledge, there are no authoritative source documents to define how many times you should rinse glassware. The logic behind a triple rinse is that, in filling and emptying a vessel three times with water, each time you are diluting by 2 orders of magnitude. In theory . . .
Q. We are currently using a solvent and we want to switch to a safer product, such as a water-based cleaner. Do you have a detergent that can assist in the removal of residual silicone oils that are left in medical device mold inserts manufactured using clear rubber material? Will Alconox detergent work as your web page says without ultrasonic?
