    I believe that Dr. Tim Sandle wrote some lovely words about Dr. Trr Meltzer. Ted was one of my father's best friends. My dad was Dr. Warner Max Linfield. I met Yed and his beautiful and devoted wife on various occasions. Ted lived a long life. B"H.

    Hello Tim I wanted to get your contact details to ask a question about Active Air Sampling and why all tables from FDA 2004 Aseptic Guidance, to USP 1116, GMP etc do not standardize on a media dish set diameter? For example all tables for settle plates state 90mm but for active air sampling there is no set diameter for the media dish - Some Air Samplers can use both 55mm and 90mm but use the same tables to verify CFU's are within alarm limits. But there is a considerable bigger surface area on a 90mm dish compared to a 55mm dish so this issue is really concerning me - do you know why there is no set diameter for media dish?
