Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 13 cu.ft., Manual Defrost Overview
The Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 13 cu.ft., Manual Defrost (model LTF401UP) is a laboratory upright freezer for reliable cold storage. Yamato Scientific builds this 13 cu.ft. cabinet to hold samples from 0°C down to −40°C. Standard equipment includes a touch-screen digital controller, audible and visual alarms, remote alarm contacts, USB and Ethernet ports, data acquisition, and alarm battery back-up.
Galvanized steel construction supports long-term sample security. A 14-gauge zinc-coated galvanized steel chamber forms the interior, while the exterior uses 16-gauge steel finished in powder-coated cool gray. Four adjustable shelves divide the chamber into five compartments and hold up to 15 racks across 370 L of usable space. Single-stage refrigeration with one hermetic compressor and a CFC- and HCFC-free refrigerant drives the air-cooled, coolant-free condenser.
Electrical options cover 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", with a shipping weight of 850 lbs. Built in the USA and UL Listed, this freezer ships from LabSupplies.com as an authorized Yamato Scientific dealer. Every unit undergoes seven days of factory testing before shipment.
Key Features
- Touch-screen control system: displays set point and chamber temperature, with Hi/Low alarm plus email and SMS notification, downloadable data logging via USB or FTP, multi-level security, and VNC remote access from a PC or smart device.
- Battery-operated alarm system: audible and visual signal on mechanical or electrical failure, over- and under-temperature settings, alarm silencing switch, battery test switch, and a relay for remote alarm hook-up.
- CFC- and HCFC-free refrigeration: single-stage system with one hermetic compressor and an air-cooled condenser that requires no liquid coolant.
- 370 L storage layout: four adjustable shelves create five compartments and accommodate up to 15 racks.
- 1/2" access port: portholes in the left-hand side of the cabinet, supplied with plugs for probes or sensor leads.
- Factory-validated performance: each freezer runs a 7-day test and maintains a constant low set point in warm +30°C ambient environments.
How to Choose the Right Low-Temp Freezer
Matching a freezer to your workflow means weighing storage volume against sample security, site power, and floor space. Use these axes to confirm the unit fits your lab before purchase.
- Capacity: 13 cu.ft. (370 L) with 15-rack capacity suits mid-volume sample libraries; estimate growth so shelving and rack counts cover future inventory.
- Temperature range: a 0°C to −40°C span fits reagents, enzymes, and many biological samples that do not require ultra-low −80°C storage.
- Control and monitoring: touch-screen control with data logging, remote VNC access, and email/SMS alarms matters for labs that need audit trails and unattended oversight.
- Voltage and site power: confirm your circuit against the 115V, 208V, 230V, or 220V single-phase options before installation.
- Footprint: verify the 35" × 34.5" × 79.5" exterior and 850 lb weight against door clearances and floor loading.
- Safety and defrost: manual defrost plus battery-backed alarms and remote relay contacts protect samples during failures and routine maintenance.
