Key Features
- Battery-backed alarm system: audible and visual signals trigger on mechanical or electrical failure, with over- and under-temperature settings, an alarm silencing switch, and a battery test switch.
- Configurable storage: four adjustable shelves form five compartments and hold up to 25 racks within the 626 L chamber.
- Factory-tested performance: every freezer runs a 7-day test and holds its low setpoint in warm ambient conditions up to +30°C.
How to Choose the Right Low-Temp Freezer
Selecting a low-temperature upright freezer comes down to matching capacity, temperature performance, and site power to your storage program. Weigh these criteria against your sample volume and lab infrastructure before specifying a unit.
- Capacity: interior volume (here 22 cu.ft. / 626 L) and rack count determine how many samples you can store; size to current load plus future growth.
- Voltage and power: match the freezer to available circuits; this model supports 115V, 208V, 230V, and 220V single-phase configurations.
