Anresco employs several of the most knowledgeable analytical chemists on this planet. Our laboratory co-directors and segment supervisors normal over twenty five many years of encounter within their respective fields of chemistry, chromatography, microbiology and microscopy.
This procedure applies to all media which happens to be used for microbiological testing from the Microbiology laboratory at PharmaInfo Restricted.
It may be supplemented with supplemental factors or indicators to help specific growth requirements or to detect precise metabolic pursuits or reactions.
In GPT failure instances, once again put together contemporary wide range of dehydrated media from your similar media container and accomplish GPT again.
dilakukan setiap bets media karena setiap pembuatan media terdapat beberapa titik kritis yang dapat mempengaruhi kesuburan suatu media. Berikut beberapa titik kritis pada pembuatan media untuk uji mikrobiologi:
