Work station (top) and sample workflow (bottom) for processing oocytes for storage in vials with in a controlled RH chamber. Within each batch three samples of dried oocytes (green) were taken out of the microwave (a) after 15 min and either directly rehydrated or stored in glass vials (c). Remaining samples were processed for an additional 15 min. At each time point one sample was used for quality control purposes to evaluate the moisture content (red) with a Karl Fisher titrator (b).
