Platinum Chest Style Ultra Low Freezers -40°C To -80°C, 27 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezer (model ULF901CP) from Yamato Scientific is a 766 L / 27 cu.ft. laboratory freezer holding a stable range of -40°C to -80°C. Sold by LabSupplies.com, authorized dealer, this chest-style unit accepts up to 48 racks for high-density sample storage. Manual defrost keeps the design serviceable.
A cascade refrigeration system pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants. Air-cooled condensing through two heavy-duty fans removes the need for liquid coolant. Construction centers on a 14-gauge zinc-coated galvanized steel chamber, while the 16-gauge steel exterior carries a powder-coated cool gray finish.
Electrical options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 98" × 36" × 43.5", with a shipping weight of 1,125 lbs. Built in the USA and UL Listed, the freezer ships from USA inventory ready for installation.
Key Features
- Touch-screen controller: displays set point and chamber temperature, logs data, and supports VNC remote access via PC or smart devices.
- Alarm system: battery-operated audible and visual signaling on mechanical or electrical failure, with over- and under-temperature settings, silencing switch, and battery test switch.
- Connectivity: USB and Ethernet ports enable data acquisition and downloads via USB or FTP, plus Hi/Low alarms with email and SMS notification.
- Cascade refrigeration: two hermetic compressors and air-cooled condensing with CFC- and HCFC-free refrigerants reach -80°C without liquid coolant.
- Power-failure recovery: automatic timer restarts the unit after an outage, backed by alarm battery back-up and dry-contact remote alarm relays.
- Access port: a 1/2" porthole with plugs on the left-hand cabinet wall routes probes and lines into the chamber.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage volume, temperature performance, and site infrastructure to your sample protocol. Review these axes before purchase.
- Capacity and rack count: a 27 cu.ft. / 766 L chamber holding 48 racks suits high-volume biorepositories; confirm your sample throughput against available rack space.
- Temperature range: a -40°C to -80°C span covers most long-term biological storage; verify the lowest set point your samples require.
- Control type: a touch-screen controller with data logging, remote access, and SMS/email alarms matters when chain-of-custody and audit records are mandatory.
- Voltage and site power: confirm available circuits, since this unit offers 115V, 208V, 230V at 60 Hz and 220V at 50/60 Hz single-phase.
- Footprint and access: chest-style loading needs overhead clearance; check the 98" × 36" × 43.5" exterior against your lab layout.
- Backup and safety: battery alarm back-up, power-failure recovery, and optional CO₂/LN₂ systems protect irreplaceable samples during outages.
