Low-Temperature Freezers (0°C to −40°C)

Yamato Scientific low-temperature freezers store samples, reagents, and biologicals between 0°C and −40°C for clinical, research, blood-bank, and industrial labs. LabSupplies.com is an authorized Yamato dealer offering the full LTF range — chest and upright formats from 2 to 28 cu.ft., in standard and Platinum touch-screen configurations. Every freezer is made in the USA and ships from USA inventory.

Why Yamato LTF low-temperature freezers

• Single-stage reliability — one hermetic compressor with CFC- & HCFC-free refrigerant delivers efficient, dependable cooling across the 0°C to −40°C range.
• Guaranteed in warm rooms — every freezer is fully tested for 7 days under demanding conditions; the constant low setpoint is guaranteed even in warm (+30°C) ambient environments.
• Battery-backed alarm — audible and visual alarm on mechanical or electrical failure, with over/under-temperature settings, silencing switch, battery test, and a relay for remote alarm hook-up.
• Rugged construction — 14-ga. zinc-coated galvanized steel chamber, 16-ga. steel exterior with a powder-coated cool-gray finish.

Formats

• Chest (horizontal) — top-opening, 2 to 27 cu.ft. (LTF-001C–901C). Best cold-air retention and the widest capacity range.
• Upright (vertical) — front-opening with 4 adjustable shelves across 5 compartments, 13 to 28 cu.ft. (LTF-401U–901U). Space-efficient footprint and organized access.

Standard vs Platinum

Standard LTF models use a digital controller with two displays — one for the set temperature, one for the actual chamber temperature. Platinum (CP/UP) models add a touch-screen controller with Hi/Low alarm and email & SMS notification, alarm-relay and power-failure dry contacts, battery back-up, a viewable temperature graph, data logging downloadable via USB or FTP, multi-level security, and VNC remote access from a PC or smart device — plus a ½" access port for probes.

Selection criteria

• Capacity — 2 cu.ft. benchtop to 28 cu.ft. floor-standing; size to your rack or sample-box count.
• Chest vs upright — chest for maximum cold retention and capacity; upright for a smaller footprint and shelved organization.
• Control & monitoring — standard digital for routine storage; Platinum for remote alarming, audit-ready data logging, and networked monitoring.
• Back-up — optional CO₂ and LN₂ back-up systems, racks, chart recorder, and cold safety gloves.
