Lost in boxes in your ULT freezer?
To make scientific life easier, we strongly recommend placing storage boxes (also known as freezer boxes) within the ULT freezer in freezer racks. These metal racks enable optimal use of space as well as easy relocation of sample boxes.
Drawer or side access?
Which freezer rack format can I use? 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, following the PhysioCare Concept®.
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?
Standard freezer racks are available in either stainless steel or aluminum, each with its own benefits. Which material should I select for my freezer racks?
Stainless steel:
• Stable/robust for longevity and higher capacity
• Fits freezer boxes up to 136 mm × 136 mm for high flexibility regarding boxes
• Special design of drawer racks for optimized cooling conditions and improved sample safety
Aluminum:
• For freezer boxes up to 133 mm × 133 mm
• Non-corrosive anodized aluminum for long-term use
