The emergence
of larger collections of biological samples requiring
automated storage and retrieval at ultra low temperature
(ULT) presents familiar challenges to TAP in terms
of accuracy of sample identity, tracking of sample
history and continuity of controlled sample condition. |

The underlying
architecture of TAP’s established Solar
system for storage and processing of DNA has been
extended to provide storage for samples at -80°c.
As the diagram below shows, samples are stored in
standardized trays, which are arrayed at high density
in static storage racking on either side of a robotic
aisle. Robots move within the aisle to find specific
trays. The entire store, including storage racking
and robotics, is contained in an environmentally
controlled area surrounded by a sealed, insulated
enclosure. In this example the storage racking and
samples are held in compartments maintained at -80°c.
The central aisle together with a zone holding tube
picking robots and the loading station, is held
at -20°c. |
