So-Low | Auto-Defrost Upright Laboratory Freezers for Medical & Lab Cold Storage
At Alto Med Supply, we offer So-Low Auto-Defrost Upright Laboratory Freezers designed to provide reliable cold storage for medical, laboratory, and industrial environments.
These professional-grade freezers maintain a stable temperature range of -18°C to -25°C, creating a dependable storage environment for sensitive materials such as biological samples, reagents, pharmaceuticals, and clinical supplies.
The product line includes a variety of capacity options, from space-saving single-door units to larger double-door configurations, making it easy to match storage needs with available laboratory space.
Each freezer operates on standard 115V power, allowing straightforward installation without the need for specialized electrical infrastructure.
These upright laboratory freezers feature an integrated auto-defrost system with adaptive cooling technology, which helps prevent frost buildup while maintaining consistent internal temperatures.
By eliminating the need for manual defrosting and reducing temperature fluctuations associated with traditional defrost cycles, the system helps protect valuable laboratory contents.
The units are built with solid, heavy-duty doors that provide excellent insulation and light protection, while durable exteriors made from high-impact painted steel or stainless steel support long-term performance in demanding work environments.
Inside, adjustable shelving allows laboratories to organize samples and supplies efficiently.
For enhanced monitoring and compliance, each freezer includes a digital microprocessor temperature controller with clear temperature readouts and programmable alarm settings.
High and low temperature alerts help staff quickly identify potential issues, supporting the safe storage of critical materials.
The cabinets are also equipped with heavy-duty swivel casters with front-locking brakes, making it easy to move the unit for cleaning, maintenance, or laboratory reconfiguration.
With dependable temperature control, durable construction, and low-maintenance auto-defrost functionality, So-Low upright laboratory freezers provide an efficient solution for secure laboratory cold storage and cold-chain management.
