How to Choose the Right Low-Temp Freezer
Selecting a low-temperature laboratory freezer comes down to matching chamber performance and site infrastructure to your storage protocol. Use the criteria below to confirm the LTF401U fits your workflow before ordering.
- Temperature range: verify your samples store safely within 0°C to -40°C; protocols requiring colder ultra-low storage need a different class of unit.
- Capacity: confirm 13 cu.ft. (370 L), four adjustable shelves, and 15-rack capacity accommodate your sample volume and organization scheme.
- Voltage: match the freezer to your available circuit — 115V, 208V, or 230V at 60 Hz, or 220V at 50/60 Hz, single-phase.
