Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 25 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 25 cu.ft., Manual Defrost (model ULF701UP) is an upright laboratory ultra-low freezer from Yamato Scientific built for long-term sample preservation. Rated across a -40°C to -85°C range, the cabinet provides 710 L (25 cu.ft.) of usable interior capacity. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants for stable pull-down without liquid coolant. An air-cooled condenser rejects heat using two heavy-duty fans. Chamber construction is 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel powder-coated in cool gray. Four adjustable shelves create five compartments and accept up to 30 racks.
Power options span 115V, 208V, and 230V at 60 Hz single-phase, plus a 220V 50/60 Hz single-phase configuration. Exterior dimensions measure 50" × 37" × 79.5", with a unit weight of 1,125 lbs. Made in the USA and UL Listed, the freezer integrates a touch-screen controller, audible and visual alarms, battery back-up, USB and Ethernet ports, and a 1/2" access port.
Key Features
- Touch-screen digital control: displays set point and chamber temperature, with viewable temperature graph, data logging, multi-level security, and VNC remote access via PC or smart devices.
- Comprehensive alarm system: battery-operated audible and visual signals on mechanical or electrical failure, with over- and under-temperature settings, silencing switch, and battery test switch.
- Cascade refrigeration: two hermetic compressors run CFC-free R-508B and R-404A refrigerants, supported by an air-cooled, dual-fan condenser that needs no liquid coolant.
- Connectivity and monitoring: USB and Ethernet ports, data acquisition, Hi/Low alarm with email and SMS notification, plus alarm-relay and power-failure dry contacts for remote hook-up.
- Power-failure recovery: an automatic timer system restarts the unit after a power interruption, backed by alarm battery back-up.
- Sample organization and access: four adjustable shelves form five compartments holding up to 30 racks, with a 1/2" porthole and plugs in the left-hand cabinet wall.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching sample volume, target temperature, and your facility's power and footprint constraints. Weigh the following axes .
- Capacity: match interior volume and rack count to your inventory; this unit offers 710 L (25 cu.ft.) and holds up to 30 racks across five compartments.
- Temperature range: confirm the cabinet reaches your storage class; this model operates from -40°C to -85°C for long-term biological and reagent preservation.
- Control and monitoring: decide whether you need touch-screen control, data logging, and remote email/SMS alarms for compliance and audit trails.
- Voltage and site power: verify your circuit before ordering, since this freezer is offered in 115V, 208V, and 230V 60 Hz, plus 220V 50/60 Hz single-phase.
- Footprint and weight: plan placement around the 50" × 37" × 79.5" exterior and 1,125 lb unit weight, including clearance for the air-cooled condenser fans.
- Redundancy and safety: consider optional CO₂ and LN₂ back-up systems and battery alarm back-up where sample loss carries high risk.
