So Low | Undercounter Manual Defrost Freezers | Sensitive Biological Samples and Reagents in Laboratory Clinical and Pharmacy Settings
Alto Med Supply offers the So-Low Undercounter Manual Defrost Freezers, high-performance cold storage solutions designed for laboratory, clinical, and pharmacy environments.
These compact freezers maximize floor space while maintaining consistent low temperatures, with models ranging from -20°C, -25°C, and -30°C, and heavy-duty units capable of reaching -40°C.

Available in capacities from 1.5 to 4.0 cubic feet, these units are built for precision and regulatory compliance.
Select models include integrated datalogging for USB-based temperature monitoring and digital record-keeping, ensuring seamless documentation.
Microprocessor temperature controllers, audible and visual alarms for power or temperature fluctuations, and keyed door locks provide enhanced security and sample protection.
Operating on standard 115V power, So-Low manual defrost freezers deliver energy-efficient, reliable, and stable low-temperature storage solutions for facilities that require secure, localized cold storage.
