Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 13 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 13 cu.ft., Manual Defrost (model ULF401UP) is an ultra-low laboratory freezer from Yamato Scientific, sold by LabSupplies.com as an authorized dealer. This upright unit holds 13 cu.ft. across five compartments and reaches -40°C to -85°C. A touch-screen controller manages set points, alarms, data logging, and remote access through USB, Ethernet, and FTP.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Cascade refrigeration uses two hermetic compressors charged with CFC-free R-508B and R-404A. Air-cooled condensing with two heavy-duty fans removes any need for liquid coolant. Four adjustable shelves create five compartments and support up to 15 racks.
Electrical options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 35" × 34.5" × 79.5", while shipping weight runs 850 lbs. Made in USA and UL Listed, the unit adds battery-backed alarms, dry-contact relays, and an automatic power-failure recovery timer.
Key Features
- Touch-screen control: displays set point and chamber temperature with a viewable temperature graph and multi-level security.
- Hi/Low alarm with notifications: sends email and SMS alerts, plus alarm-relay and power-failure dry contacts for remote hook-up.
- Battery-backed alarm system: emits audible and visual signals on mechanical or electrical failure, with over/under-temperature settings, silencing switch, and battery test switch.
- Cascade refrigeration: two hermetic compressors and air-cooled condensing with two heavy-duty fans, using CFC-free R-508B and R-404A.
- Data acquisition and remote access: data logging downloadable via USB or FTP, plus VNC remote access from PC or smart devices.
- Power-failure recovery and access port: automatic timer restarts the unit after an outage, and a 1/2" side porthole supports probes and lines.
How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab depends on sample volume, target temperature, site power, and the monitoring your protocols require. Weigh these axes .
- Capacity: 13 cu.ft. (370 L) with 15-rack support fits mid-sized biorepositories; size to your current inventory plus expected growth.
- Temperature range: a -40°C to -85°C envelope covers most cell-line, enzyme, and biological sample storage; confirm your coldest required set point.
- Control and monitoring: touch-screen control with email/SMS alarms, data logging, and remote VNC access matters for labs under audit or chain-of-custody rules.
- Voltage and site power: verify your outlet matches the 115V, 208V, or 230V 60 Hz option before delivery to avoid install delays.
- Footprint: exterior dimensions of 35" × 34.5" × 79.5" and 850 lbs require a planned floor location with clearance for the air-cooled condenser.
- Backup and continuity: battery-backed alarms and power-failure recovery protect samples; optional CO₂/LN₂ back-up adds redundancy for critical inventory.
