- Capacity: the 766 L / 27 cu.ft. chamber and 48-rack support determine how many samples and racks you can store per unit.
- Voltage: confirm your circuit matches one of the 115V, 208V, 230V (60 Hz) or 220V (50/60 Hz) single-phase configurations.
- Footprint: verify the 98 × 36 × 43.5-inch exterior and 1,125 lb shipping weight fit your floor plan and access path.
