Thermo Scientific™ Cryogenic Storage Chest Freezers

Description

• Maintain uniform temperatures of -140° and -150°C (safely below the -130°C glass transition temperature of water) with Thermo Scientific™ Cryogenic Storage Chest Freezers
• These freezers offer mechanical cryopreservation for long-term biological storage and are safer and more convenient than LN 2 systems
• Features : Top-to-bottom temperature uniformity is dramatically improved when compared to LN 2 vapor
• Cell viability is improved as biologically relevant, thermally driven reactions are not known to occur
• System offers manual defrost
• Refrigeration System: Exclusive mixed refrigerant autocascade with a single, orbital air-cooled compressor Downfeed evaporator High-capacity air-cooled condenser with dual condenser fans Washable condenser filter IntrLogic™ Microprocessor Control System: Touchpad data entry with digital display of all functions Key-operated main power and alarm switch for setpoint security Setpoints adjustable in 1°C increments Independent operating temperature and high/low limit alarm functions Alarm System: Power failure or temperature deviation triggers audible and visual warning
• Automatic Incident Monitor identifies temperature deviation beyond alarm setpoints
• System includes adjustable safety alarm with automatic, continuous charge battery backup and digital battery indicator
• System includes touchpad alarm test function RS-232 data port with system software
• Exterior alarm contacts for connection to remote monitoring system
• Monitoring System: Lifeguard compressor protection to monitor performance and automatically adjust to internal and external conditions Extreme Ambient Alert that warns if room temperature can affect performance Voltage Boost Indicator that advises of low source voltage below safe parameters and indicates voltage boost system is activated On-board power monitoring with digital readout of incoming line voltage Built-in surge suppressor "Clean Filter" indicator Construction: Low-profile design for easy access to inventory Heavy-gauge steel cabinet with high-impact powder paint finish Heavy-duty counterbalanced lid with integrated keyed lock and independent sublids Double-seal lid gaskets minimize frost buildup Minimum 5″ (12.7cm) foamed-in-place closed-cell, CFC-free urethane insulation Access port, 1″ (2.54cm) diameter, with cap Recessed heavy-duty swivel casters Ordering Information: Uses standard Thermo Scientific inventory racks and fiberboard boxes, available separately. 208/230V model comes with P6 plug
• 380V and 220/240V models require a hardwire connection.
