Platinum Chest Style Low Temperature Freezers 0°C To -40°C, 12 cu.ft., Manual Defrost Overview
The Platinum Chest Style Low Temperature Freezers 0°C To -40°C, 12 cu.ft., Manual Defrost (model LTF401CP) is a chest-style laboratory freezer from Yamato Scientific, holding 340 L (12 cu.ft.) across a controlled 0°C to −40°C range. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. A single-stage refrigeration system drives one hermetic compressor through an air-cooled condenser, removing the need for liquid coolant. Refrigerant is CFC- and HCFC-free. Interior space accepts up to 27 racks within a 55" × 19" × 20" chamber.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 65.5" × 32" × 47.5", with a shipping weight of 825 lbs. Built in the USA, this freezer carries UL Listed certification. Every unit passes a 7-day performance test before it ships.
Key Features
- Touch-screen digital control: displays set point and chamber temperature, with a viewable temperature graph and multi-level security access.
- Remote monitoring & data logging: Hi/Low alarm with email and SMS notification, downloadable logs via USB or FTP, and VNC remote access from a PC or smart device.
- Battery-backed alarm system: audible and visual signal on mechanical or electrical failure, over- and under-temperature settings, alarm-silence switch, and battery-test switch.
- Remote contacts: alarm-relay and power-failure dry contacts plus a relay for remote alarm hook-up.
- 1/2" access port: porthole on the left-hand side of the cabinet, supplied with plugs for sensor and probe pass-through.
- 7-day factory testing: each freezer is fully tested under demanding conditions and holds a constant low setpoint in warm (+30°C) ambient environments.
How to Choose the Right Low-Temp Freezer
Selecting a chest-style low-temperature freezer comes down to matching capacity, temperature class, and site power to your workflow and sample volume. Use the criteria below to confirm the right fit before purchase.
- Capacity: this unit holds 340 L (12 cu.ft.) and up to 27 racks — confirm your sample inventory and rack format fit the chamber footprint.
- Temperature range: a 0°C to −40°C window suits long-term storage that does not require ultra-low (−80°C) conditions; match the range to your sample stability requirements.
- Control type: touch-screen control with data logging and remote alerts matters for labs that document chain-of-custody or need off-site failure notification.
- Voltage and site power: verify your facility circuit against the available 115V, 208V, 230V (60 Hz) and 220V (50/60 Hz) single-phase options.
- Footprint: the 65.5" × 32" × 47.5" exterior and 825 lb weight should be checked against doorways, floor loading, and bench-side clearance.
- Safety and backup: battery-backed alarms and optional CO₂/LN₂ back-up systems protect samples during power or mechanical failures.
