New “High-Density” Rack: Even More ULT Storage Capacity in the Same Space

By Jim Miller, Stirling Ultracold Chief Revenue Officer

Our 600-box SU780XLE ultra-low freezer already stores the most samples per floor space area of any comparable model. With the new “High-Density” Storage Rack solution, it can now store 100* more boxes in the same footprint! Storing up to 700* two-inch sample boxes, this optional rack solution further increases the freezer’s storage density to 81.6 boxes per sq. ft/m of floor space, which is 35-70% more ULT storage per floor space area than similarly-sized freezer models.

The High-Density Storage Rack is a perfect solution for laboratories and biorepositories with limited space who want to expand biological sample inventories without new construction. The ability to store more samples in a smaller freezer footprint not only reduces your cost per sq. ft/m, but offers the potential of replacing older ULT models with fewer freezers to reduce capital costs.

Considering that the SU780XLE is the most energy-efficient ENERGY STAR®-certified ULT freezer, this new 700-box rack furthers its efficiency per sample. In fact, the XLE uses 20-60% less energy per sample than other ENERGY STAR-certified ULT freezers (energy consumption data source: energystar.gov) in the high-density configuration. This not only enhances energy savings for all users, and potentially reduces the number of units required, but particularly benefits commercial biorepositories by improving profitability with the lowest operating cost per sample stored.

* To keep the vacuum release port unobstructed on the SU780XLE, it is recommended that one box be removed from the High-Density Storage Rack. This will reduce storage capacity to 699 2-inch boxes in the high-density configuration.
