The Yamato LTF-801UP is the largest upright in the LTF Platinum line — a 792 L (28 cu.ft) upright low-temperature freezer holding 0 °C to −40 °C, organized into five compartments behind four adjustable shelves with a door-mounted touch-screen controller. The Yamato LTF-801UP delivers maximum −40 °C capacity with eye-level access, and — because every LTF is factory-tested for seven days — guarantees its setpoint in warm (+30 °C) rooms. Its Platinum controller adds Hi/Low alarms with email and SMS notification, USB/FTP data logging, and VNC remote access. It is the top upright for high-turnover labs consolidating a large −40 °C inventory.

Application Profile
When a lab needs maximum −40 °C capacity but still wants eye-level, compartmented access, the largest upright is the answer. The LTF-801UP delivers 792 L across five inner-door compartments behind four adjustable shelves, consolidating a large inventory into one footprint while keeping racks sorted and reachable without the deep reach a chest requires. Because this material stores correctly above ultra-low, a right-sized single-stage low-temperature freezer holds it more efficiently than filling an −80 °C ultra-low would (see cold-storage-selection).
Compartmented inner doors limit cold-air loss during the frequent retrievals a large shared freezer sees, protecting the whole archive; every LTF is factory-tested for seven days, so the setpoint is guaranteed even in warm rooms. The door-mounted touch-screen Platinum controller adds the monitoring layer a modern facility expects — email/SMS alarms, downloadable temperature logs, and VNC remote access to prove the cold chain held and to catch an excursion before it becomes a loss (see cold-chain-sample-storage). A ½" access port accepts external probes, and a chart recorder plus CO₂/LN₂ back-up are available as options.
Frequently Asked Questions
How much does the LTF-801UP hold and how cold? 0 °C to −40 °C across 792 L / 28 cu.ft, on four adjustable shelves (five compartments) with a 30-rack capacity — the largest upright in the LTF Platinum line.
Why choose an upright over a chest freezer? Uprights keep samples at eye level for fast retrieval and inventory; the five inner-door compartments limit warming when you open one section, which suits high-traffic shared storage.
Low-temperature or ultra-low — which do I need? If your reagents, enzymes, and samples store correctly at −20 to −40 °C, the single-stage LTF-801UP is the efficient choice. Reserve cascade ultra-low ULF freezers (−80 °C) for material that genuinely requires it.
How does it alarm and log? A door-mounted touch-screen controller with Hi/Low alarms via email and SMS, dry-contact alarm and power-failure relays, a battery-backed alarm, and downloadable temperature logs (USB/FTP) plus VNC remote access.
Is defrost automatic? No — manual defrost, standard for laboratory low-temperature storage.
Ordering & Configuration
quote-based. The LTF-801UP is a capital low-temperature freezer sold through a quote. At quote we confirm electrical service (115 V standard, or 208/220/230 V), floor space and door-swing clearance for the 137 × 93 × 201 cm cabinet, shelf/rack configuration, and chart-recorder or CO₂/LN₂ back-up options. Warranty terms are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the LTF-801UP for your storage program.
LTF Platinum low-temperature, by format: the LTF-801UP (792 L / 28 cu.ft upright) is the maximum-capacity upright with eye-level access; step down to the LTF-601UP (626 L / 22 cu.ft) or LTF-401UP (370 L / 13 cu.ft). Choose a chest (LTF-901CP) when door-opening cold retention outranks walk-up access. For −80 °C storage, move to the ULF Platinum ultra-low line. All share the Platinum touch-screen controller and networked alarming.
