The UCF-000 is the entry point of Yamato's UCF undercounter and countertop freezer series — a 42 L (1.5 cu.ft.) solid-door lab and pharmacy freezer holding a fixed -20°C / -4°F with a mechanical dial thermostat. It is the right pick where a compact, benchtop-or-under-counter footprint and a single reliable freezing setpoint matter more than digital monitoring, alarms, or data logging. Where a facility needs alarms, adjustable setpoints, or USB data download, step up to the digital UCF-001 (48 L) or the deeper-cold UCF-101A / UCF-101B (90 L).

Application Profile
The UCF-000 suits point-of-use frozen storage where a small, self-contained -20°C freezer belongs at the bench or beneath the counter rather than in a walk-in or shared upright. It handles reagent and enzyme storage at -20°C for individual labs and shared benches, pharmacy cold-chain storage of frozen pharmaceuticals in compact clinic and dispensing settings, and sample or aliquot holding where a single fixed freezing setpoint is sufficient and continuous digital monitoring is not required. Its compact footprint also makes it well suited to satellite or overflow freezing near a workstation and to space-constrained teaching labs, clinics, and satellite facilities where footprint drives the selection.
Because the UCF-000 uses a mechanical dial thermostat with no alarm or logging, it is best matched to non-critical or backup storage. Regulated or high-value inventory that demands alarm annunciation, min/max recall, or downloadable temperature records should move to the digital UCF-001 or UCF-101 models.
Design Architecture
Refrigeration. A single hermetic compressor circulating R600a hydrocarbon refrigerant delivers the -20°C setpoint. Cooling is by gravity flow (natural convection) rather than forced air, which favors quiet, low-vibration operation and gentle handling of stored contents. The urethane-foam insulated cabinet holds temperature between compressor cycles.
Control. A mechanical dial thermostat sets the operating temperature — simple, robust, and field-serviceable, with no electronics to fail. There is no digital display, alarm relay, back-up battery, or data-logging capability on this model.
Cabinet and access. The painted-steel exterior with steel interior houses 1 fixed shelf. A 3/8"-diameter access port allows probe or tubing pass-through for independent temperature verification. The keyed lockable solid door secures contents; 4 leveling legs stabilize either countertop or undercounter placement. Manual defrost keeps the sealed system simple.
Electrical. Runs on standard 115V, 60 Hz, single-phase power drawing ~1.1A running on a 15 Amp dedicated line, terminating in a NEMA 5-15 plug — no special electrical service required.
Frequently Asked Questions
What temperature does the UCF-000 hold? A fixed -20°C / -4°F setpoint, set by a mechanical dial thermostat.
How much can it store? 42 L / 1.5 cu.ft. with 1 fixed shelf behind a solid, keyed-lockable door; external dimensions are 18.5" x 19.5" x 19.5".
Does the UCF-000 have alarms or data logging? No. This entry model uses a mechanical dial thermostat with no digital display, alarm relay, back-up battery, or data logging. For alarms, adjustable setpoints, or USB data download, step up to the digital UCF-001 or UCF-101 models.
Why does it use gravity-flow cooling? Cooling is by gravity flow (natural convection) rather than forced air, which favors quiet, low-vibration operation and gentle handling of stored contents.
What power does it require? 115V, 60 Hz, single-phase on a dedicated 15 Amp circuit, drawing about 1.1A running, terminating in a NEMA 5-15 plug — no special electrical service required.
Ordering & Configuration
Each UCF-000 ships as a complete, ready-to-run undercounter/countertop freezer: cabinet, 1 fixed shelf, keyed lock, 4 leveling legs, and NEMA 5-15 cord. Chart recorder and cold safety gloves are available as optional accessories.
