Location: Virtual | 10:00 a.m. – 11:00 a.m. ET*

To effectively control bioburden from entering cleanrooms and biological safety cabinets (BSCs), it is essential to implement a robust contamination control strategy (CCS) that supports the aseptic transfer of critical items into controlled environments.

Join this complimentary webinar to discover proactive strategies to prevent contamination from viruses, bacterial and fungal spores and vegetative bacteria. Explore real-world case studies from advanced therapy medicinal products (ATMP) cleanrooms and gain insights into bioburden control through high-risk transfer points. This session will also highlight published data that supports proven methods for maintaining aseptic conditions and protecting critical environments.


* Please note that the webinar broadcast time is listed in the Eastern Time Zone (ET). If necessary, be sure to convert to your local time zone.
