Aseptic Processing Isolators (Presentation) by Richard L. Friedman, MS June 7, 2001
The highlights of this presentation by a leading FDA-CDER authority on aseptic processing isolator systems include basic design and validation approaches as well as feedback by FDA inspectors on various isolator applications during pre-approval inspections.
Industry Survey on Sterility Testing Isolators: Current Status and Trends by Carmen M. Wagner, Ph.D. and Jennifer Raynor, Pharmaceutical Engineering March/April 2001, pp. 134-140
This article presents the current results of an ongoing survey assessing the implementation status of sterility test isolator systems worldwide. The results from the survey confirmed that sterility testing in isolators is now the "norm" vs. being a novelty. One key finding of the survey was that these systems have been predominantly placed in unclassified, although controlled access, areas.
Equivalency Testing for Multiple Isolator Systems by James R. Rickloff, MS, Principal Scientist 5-Mar-01
A second identical isolator can be shown equivalent to another through the use of a single test if all critical decontamination cycle parameters can be duplicated.
Key Aspects of Validating Hydrogen Peroxide Gas Cycles in Isolator Systems by James R. Rickloff, M.S., Journal of Validation Technology,pp. 61-71 November 1998
The purpose of this paper was to revisit some essential validation aspects of sanitizing isolators with H202 gas in order to assist the industry in demonstrating reproducibility of the process under worst-case conditions.
Practical Validation Strategies for Isolated Sterility Testing Labs - Part II (Presentation) by James R. Rickloff, MS June 13-14, 2002
The second part of the Workshop focused on the Performance Qualification studies that are needed to properly validate the gaseous decontamination method in sterility test isolator systems. Practical examples, a discussion of acceptance criteria, and the demonstration of test methods were included. Key learning objectives included determining a D-value for your BIs, developing and qualifying decontamination cycles, isolator aeration, sterilant ingress methods, and creating a meaningful process simulation (no false negative) study.
Current Trends and Concepts in Validating Sterility Testing Isolators (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.
Hydrogen Peroxide Gas Sterilization: A Review of Validation Test Methods by James R. Rickloff, Joseph P. Dalmasso, Ph.D., and Lisa W. Lyhte, American Sterilizer Company, Apex , North Carolina, Proceedings of the PDA Annual Meeting 1992
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.
The Effect of VHP® on Testing Devices & Culture Media Used in Sterility Test Isolators (Presentation) by Michelle Stafford October, 2 2001
This presentation reviewed the physical and microbiological testing performed by Millipore on Steritest canisters following their exposure to hydrogen peroxide gas. The microbiological test results on new line of agar plates containing a sterilant neutralizer were also shared with the attendees.
Implementing Validation Strategies for Isolator-Based Systems (Presentation) by Leslie M. Edwards, MSE and James R. Rickloff, MS January 27-28, 2003
This presentation thoroughly reviewed the overall strategies and basic validation methodologies for isolator system validation utilizing gaseous decontamination methods. Facility design and qualification, equipment qualification, performance qualification, and process simulation testing was reviewed, with practical examples and demonstrations of key methods and techniques.
