Abstract
Broadly speaking, embodiments of the present technique provide apparatus for controlling ice formation, such as during the processes of cryopreservation and freeze drying. In particular, the apparatus provides a mechanism to deliver an ice nucleating material into a biological sample that is to be preserved, without allowing the ice nucleating agent to contact or contaminate the biological matter within the sample.
