Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 25 cu.ft., Manual Defrost Overview
The Platinum Upright Style Low Temperature Freezer LTF701UP is a 25 cu.ft. (710 L) laboratory freezer from Yamato Scientific, holding chamber temperatures from 0°C to −40°C with manual defrost. Sold by LabSupplies.com as an authorized dealer, this upright cabinet pairs a touch-screen digital controller with email and SMS Hi/Low alarms, dry-contact relays for remote monitoring, battery-backed alarms, and a 1/2" access port for probes or tubing.
Construction centers on a 14-gauge zinc-coated galvanized steel chamber and a 16-gauge steel exterior finished in powder-coated cool gray. Refrigeration runs on a single-stage system driven by one hermetic compressor and a CFC- and HCFC-free refrigerant. An air-cooled condenser needs no liquid coolant, while four adjustable shelves create five compartments and accept up to 30 racks.
Electrical options cover 115V, 208V, and 230V at 60 Hz, single-phase, plus 220V at 50/60 Hz, single-phase. Exterior dimensions measure 50" × 37" × 79.5", and the unit ships at 1125 lbs. Built in the USA and UL Listed, every freezer is run-tested for 7 days, with a stable low setpoint validated in warm +30°C ambient conditions.
Key Features
- Touch-screen control: digital controller displays set point and chamber temperature, with a viewable temperature graph and multi-level security.
- Alarm and notification system: audible and visual Hi/Low alarms trigger email and SMS alerts, backed by alarm-relay and power-failure dry contacts plus a battery back-up.
- Connectivity and data logging: USB and Ethernet ports support data acquisition, FTP and USB downloads, and VNC remote access from a PC or smart device.
- 1/2" access port: a left-side porthole with plugs routes probes, sensors, or tubing into the chamber.
- Storage configuration: four adjustable shelves form five compartments and accommodate up to 30 racks within the 710 L interior.
- CFC- and HCFC-free refrigeration: a single-stage hermetic compressor with an air-cooled condenser eliminates liquid coolant requirements.
How to Choose the Right Low-Temp Freezer
Selecting an upright low-temperature freezer comes down to matching chamber performance and site power to your sample volume and monitoring requirements. Weigh these axes against your lab layout and protocol before specifying a unit.
- Capacity: interior volume and rack count determine how many samples fit; this model offers 25 cu.ft. (710 L) and up to 30 racks across five compartments.
- Temperature range: confirm the cabinet reaches and holds your target setpoint; 0°C to −40°C suits enzymes, reagents, and many biological samples that do not require ultra-low storage.
- Control type: touch-screen digital control with data logging and remote alarms supports audit trails and unattended monitoring that analog dials cannot.
- Voltage and site power: verify available circuits against the unit's 115V, 208V, 230V, or 220V single-phase options to avoid retrofit costs.
- Footprint: measure doorways and floor space against the 50" × 37" × 79.5" exterior and 1125 lb weight before delivery.
- Safety and redundancy: battery-backed alarms, power-failure contacts, and optional CO₂/LN₂ back-up protect samples during outages.
