Redipor barrier pack overcomes VHP decontamination issues

The Redipor barrier pack from Cherwell Laboratories of Bicester in the UK has been developed in response to increased use of vaporised hydrogen peroxide (VHP) decontamination. It ensures that there are no false negatives following the use of VHP for sterilising isolators, cleanrooms and pharmaceutical processing equipment. All Redipor barrier packs have a clear gas impermeable layer, which is guaranteed to prevent the ingress of decontamination gases such as VHP, while still allowing easy examination of the contents. They are also easy to open with gloved hands and each pack has a convenient hole punched outside the seal to facilitate its hanging for decontamination purposes.

The performance of the packaging has been tested and fully validated using Hydrogen Peroxide (H2O2) detectors capable of detecting <1ppm. After repeated decontamination cycles using peak concentrations of >570ppm, no H2O2 was detected inside the pack. During production of the Redipor barrier packs agar plates are poured aseptically on automated filling lines, conditioned at room temperature and every plate is inspected before being sealed into the transparent, VHP impermeable bag. These are then over bagged with polythene, sealed, packed in lined boxes, sealed again and finally irradiated. Every batch of plates is tested for growth promotion after irradiation, with the results detailed on an accompanying certificate.

The Redipor irradiated prepared media can be used for a variety of applications within the pharmaceutical production environment, such as environmental monitoring, sterility testing, operator validation and quality control. In addition to plates, the Redipor media are available in ampoules, injection bottles, vials and infusion bags. www.cherwell-labs.co.uk

    Avoiding glass delamination Contamination with glass flakes caused by delamination of the internal finish of container closure systems or prefilled syringes has caused numerous drug recalls. Surface imperfections and aggressive drug components can lead to interaction between product and container, resulting in leaching, dissolution, ion exchange and formation of precipitants or particles; use of cyclic olefin polymers as an alternative to glass can avoid these issues
