ScienTemp Corporation 85-3.1 Low Temperature Chest Freezer, 3.1 cu. ft., -45 C to -85 C, 41" Width, Polyurethane, 115 or 230 Voltage Options

The Model 85-3.1 Ultra-Low Temperature Chest Freezer is a precision-engineered solution specifically designed to meet the rigorous thermal stability requirements of clinical, research, and industrial laboratories.

Capable of maintaining an uncompromising environment between -45°C and -85°C, this unit ensures the long-term integrity of sensitive biological samples, vaccines, and specialized materials. Its sophisticated dual-stage refrigeration system, powered by a robust 1/2 hp compressor, works in tandem with high-density polyurethane insulation to provide rapid pull-down times and exceptional recovery after door openings.

Safety is prioritized through an integrated digital controller that provides real-time monitoring alongside both visual and audible alarm systems to prevent catastrophic sample loss.

The compact 3.1 cubic foot interior is housed within a durable exterior that includes heavy-duty locking casters for effortless mobility and a keyed hasp lock for enhanced security in shared workspaces. By utilizing a gravity-based air circulation and cold wall evaporator design, the unit minimizes interior frost buildup while maintaining uniform cooling throughout the chamber.

Whether utilized for genomic research or pharmaceutical storage, the Model 85-3.1 delivers the industrial-grade performance and reliability essential for modern cold-chain management.
