Freezers, Laboratory Freezer, High-Performance, Revco®
Thermo Scientific Revco high-performance laboratory freezers feature microprocessor control for simplified operation and greater accuracy. Revco 0°C and -20°C high-performance freezers are designed for medical and scientific applications such as storage of reagents, pharmaceuticals, biologicals, or other commonly used laboratory materials. Models offer cabinet sizes to fit a variety of space needs and storage volume requirements.
Features
- Temperature factory-preset at -20° or -30°C
- Capacities from 4.9 to 51.1 cu.ft. (139 to 1447L)
- Icon-based controls and displays
- Large, easy-to-read digital display shows temperature within 1°C
- Graphic thermometer is steady green when temperature is normal, flashes top bar for overtemperature, flashes bulb for undertemperature
Microprocessor Control
- Audible/visual warnings for overtemperature, undertemperature, or power failure
- Key-operated OFF/ON/ALARM ON master switch for setpoint security
- Push-button alarm test
- Remote alarm contacts
- Alarm silence, ringback, and auto reset
- Controller battery backup system
Construction
- Scratch-resistant cold-rolled steel interior and exterior finishes
- High-density, 2 inch thick (5.1cm) CFC-free urethane foam insulation protects against ambient temperature fluctuations
- CFC-free, HFC-blend refrigerant
- Single-door models are hinged on right
- Full-length door handle and key lock
- Doors self-close and lock open at 90°
- Adjustable epoxy-coated wire shelves
- 1 inch (2.5cm) diameter access port with plug on undercounter model
-30°C Freezers
- Automatic defrost and condensate removal
- Sensor automatically initiates defrost cycle on demand, eliminating need for a defrost timer, minimizing frost buildup, and optimizing coil efficiency
- Forced-air circulation improves temperature uniformity, provides faster recovery after door is opened
-20°C Freezers
- Suitable for applications in which slight intermittent coil warming during an automatic defrost cycle is not desired (such as enzyme storage)
- Gravity convection air system for maximum stability without a blower or fan
- Manual defrost
Ordering Alerts: Alarm systems, temperature chart recorders, and power monitors are available separately.
