This unique personal-sized 120V/60Hz Innova U101 ultra-low temperature laboratory freezer is designed for use on or under the lab bench. It utilizes vacuum insulation panel technology to offer up to 30% more storage capacity than traditionally-insulated lab freezers, without altering external dimensions. It has a flush, front-mounted control panel that is easy to read and reach, featuring a bright LED display and a flat touch-keypad for easy cleaning that is mounted at eye-level. The easy-to-open door allows one-handed operation, while the cam latch ensures secure door closure. The heated air vent with a spring-assisted plunger to break ice prevents vacuum formation, allowing the door to be re-opened quickly. It has a front-mounted washable air filter that is easily accessible without tools. The insulated inner doors have molded grips and ice-proof latches and easily lift off without tools for defrosting and cleaning. It is easily mobile with rear rollers, and has low noise and low heat output. The Model U101 has a programmable temperature control system with a temperature range from -50°C to -86°C, in 1°C increments, even at ambient temperature up to 32°C. It is operated by a microprocessor-controlled temperature and alarm system featuring an automatic restart with non-volatile memory that returns setpoints to user-programmed levels after power interruptions. A user-defined 4-digit password protects alarm and temperature setpoints, preventing unauthorized users from altering settings. Keyed locks on outer doors and lids prevent unauthorized access to valuable samples. The battery back-up activates alarms and displays temperature during power outages. A lockable plate protects the on-off switch, preventing accidental shut-off. Refrigeration is provided by a hermetically-sealed, two-stage cascade system that uses industrial-grade, commercially available compressors. Two pass-through access ports allow CO2/LN2 injection or addition of probes. A unique automatic reset feature protects the microprocessor controller from harm caused by electrical spikes. It has an internal voltage stabilizer that evens out voltage fluctuations, maintaining stable power. Factory-installed RS-485 port with optional BioCommand® SFI software monitors multiple freezers simultaneously for optional remote control and data logging. Monitoring and alarms are controlled by unique S.M.A.R.T. Plus™ diagnostic software that is built into the control panel to help identify the cause of a fault or setpoint variance. Remote alarm contacts provide connection to external user-supplied alarm/monitoring systems. Audial and visual alarms include high/low temperature, power failure, low battery, filter clean, and fault analysis. The Model U101 personal-sized freezer consumes less power per kilowatt-hour than ULT freezers of similar size, resulting in lower energy bills. Rapid temperature recovery after door opening provides enhanced sample security. Covered by a five year warranty, with two years on parts and labor and an additional three years covering parts. Additionally, Innova vacuum insulation panels are warranted for twelve years. Freezer Type: Personal-Size. Model Number: U101. Insulation Method: Vacuum Insulation Panel Technology.
