How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab means weighing storage volume against bench power, footprint, and sample-protection features. Use the criteria below to confirm the unit fits both your workflow and your facility.
- Capacity: 28 cu.ft. (792 L) and 30-rack support determine how many samples and rack systems you can store without a second unit.
- Voltage: confirm your circuit matches the 115V, 208V, or 230V (60 Hz) or 220V (50/60 Hz) single-phase options before installation.
- Footprint: verify the 54" × 37" × 79.5" exterior and 1,125 lb weight clear doorways and floor-load limits.
