 (Presentation) by James R. Rickloff, MS May 25-26, 2000
|
| Past practices and current trends in validating sterility testing isolators was reviewed with an emphasis now being placed on productivity. Although, the key validation criteria remain the same, i.e. no false negatives, improvements to the overall system design have permitted the optimization of the decontamination cycle. |

|
| The importance of performing temperature distribution studies, the use of chemical and biological indicators in optimizing and verifying proper gas distribution, a technique to easily perform square-wave D-value determinations, and a means to quantitatively monitor aeration efficiency when using a prototype VHP1000 was reviewed. |

|
| This presentation provides an overview on the decontamination cycle and regulatory expectations for the process. Past flexible wall data and its' implications are reviewed and how new trends in validation techniques are implemented to reduce them. The benefits of rigid wall isolator construction are also discussed. |

|
| This presentation reviews the principles of microbial monitoring in isolators, current US and European regulatory requirements for monitoring, and the means to achieve and maintain a germ free environment. The current means to monitor the air and surfaces in isolators is also touched upon. |

| This paper compares gamma-irradiation sterilized, modified DE Agar with standard non-irradiated D/E-Agar for recovery of organisms and capacity for neutralizing disinfecting agents. The neutralizing capacity was tested using 4 microorganisms (gram positive coccos, gram positive rod) with a wide range of disinfecting agents neutralized by D/E-Agar including aldehydes, phenol, quaternary agents, chlorine compounds, and hydrogen peroxide. The radiation-sterilized medium neutralized each disinfectant as well as the non-irradiated medium and fertility was equal or better on radiation sterilized DE Agar compared with standard D/E-Agar. |
