DuPont™ Tyvek® goes to space


The Cranfield Astrobiological Stratospheric Sampling Experiment (CASS•E) was designed to address concerns of the wider scientific community that any collected microorganisms in the stratosphere are unlikely to be ground-based contamination.

A key design feature for CASS•E is the use of DuPont™ Tyvek® as a biobarrier mechanism to maintain post-cleaning and dry heat microbial reduction levels of contamination of the sampling mechanism until barrier breaching in the stratosphere.

According to one of the CASS•E researchers, Clara Juanes - Vallejo of Cranfield University, “Tyvek® ensured our experiment was a complete success and we even got awarded finalists of Innovation Engineering and Technology UK awards for the best team.”
