Abstract
A container assembly comprises a vessel for containing a biological medium, gametes and/or one or more embryo(s). The vessel has a COpermeable seal and a closure valve device for selective access. A buffer chamber for a COenriched atmosphere cooperates with the vessel and is in communication with the COpermeable wall. Such a container assembly is particularly adapted for intravaginal use in which case the permeable seal prevents ingress of vaginal secretions. The buffer chamber mediates the aqueous pH in the vessel after the container assembly is removed from a COenriched environment.
