Note that many folks do not autoclave media containing dextrose — instead they autoclave everything else, then add filtered glucose solution (2% w/v in media; e.g., add 25 mL of 40% dextrose). For vacuum filter sterilization , attach the Nalgene filter assembly (VWR cat no. 28199-303 ) to a sterile 0.5 liter bottle, attach the hose to the .It is generally accepted that terminally sterilized injectable articles or critical devices purporting to be sterile, when processed in the autoclave, attain a 10 –6 microbial survivor probability, i.e., assurance of less than 1 chance in 1 million that viable microorganisms are present in the sterilized article or dosage form. With heat-stable articles, the approach often is to considerably .
Autoclaves heat their contents to 121°C, which is 21°C over the boiling point of water. To prevent the solutions from boiling over/vaporizing, the autoclave chamber is pressurized during this process. . (e.g. Mg and glucose) Autoclave: Most buffers and salt solutions
