Currently we are following membrane filtration method. we would like to change the method from filtration to Pour plate method according to our convenience. on which basis i can change this method?.
According to USP purified water must be analyzed by membrane filtration.
dear sir if we run three samples of purified water from different location and we have signal cone assembly. so we need again and again sterilised nor not or once only? what protocol we follow for that?
You should have multi sterilized filtration cups and change them for analyzing different water samples.
For analysis of purified water and WFI bulk water can I use R2A Agar medium for total aerobic microbial count?
how much sample quantity required for pathogen testing in purified water?
Give some refference for that and which refference can i give in SOP during preparation?
