Drawer or side access?
When using racks with drawers, only the drawer with the freezer boxes of interest is pulled out. All other boxes stay in the cold inner area of the ULT freezer. Eppendorf drawers are optimized for smooth movement at -80°C for ergonomic handling.
When using side access racks, most of the storage boxes have to be pulled out of the cold inner area of the ULT freezer to access the samples.
Racks for chest freezers can be equipped with locking rods to secure freezer boxes when pulling out the rack tower.
Stainless steel or aluminum?
By standard, there are two types of rack materials available.
Stainless steel:
Stable/robust for longevity and higher capacity
For freezer boxes up to 136 mm x 136 mm for high flexibility regarding boxes
Special design for optimized cooling conditions and improved sample safety
Aluminum:
For freezer boxes up to 133 mm x 133 mm
Non-corrosive anodized aluminum for long-term use
