Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 18 cu.ft., Manual Defrost Overview
The Platinum Upright Style Low Temperature Freezer LTF501UP from Yamato Scientific is an 18 cu.ft. laboratory freezer holding a 0°C to -40°C range with manual defrost. LabSupplies.com, authorized dealer, supplies this upright unit for sample storage where stable sub-zero temperatures are required. A touch-screen controller, audible and visual alarms, and remote alarm contacts ship standard.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge powder-coated cool gray steel exterior. Four adjustable shelves create five compartments, and the cabinet accepts up to 20 racks across 505 L of interior volume. A single-stage hermetic compressor drives the air-cooled, CFC- and HCFC-free refrigeration system, so no liquid coolant is needed.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 40 × 36 × 79.5 inches, and shipping weight is roughly 900 lbs. Built in the USA, every unit is UL Listed and tested for seven days before dispatch. A 1/2" left-side access port allows external probe routing.

How to Choose the Right Low-Temp Freezer
Matching a low-temperature freezer to your workflow means balancing storage volume against the temperature class your samples demand, then confirming the unit fits your site power and floor space. Use these axes to qualify a model before purchase.
- Capacity: interior volume and rack count determine how many samples you store; this unit offers 505 L / 18 cu.ft. and holds up to 20 racks.
- Temperature range: confirm the rated band suits your samples; a 0°C to -40°C freezer fits reagents and biologicals that do not require ultra-low -80°C storage.
- Control type: touch-screen controllers with alarms, data logging, and remote access support audited storage and faster troubleshooting.
- Voltage: verify your circuit; options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase.
- Footprint and weight: the 40 × 36 × 79.5 inch cabinet and ~900 lb weight require adequate floor space, clearance, and load-rated flooring.
- Defrost type: manual defrost suits stable long-term storage where minimal temperature fluctuation matters more than hands-off maintenance.
