Ultimate Sample Protection:The dual cooling system offers the highest level of sample protection through the use of two independent refrigeration systems that maintain -86°C temperature. In the event of a malfunction in one circuit, the second circuit seamlessly takes over, sustaining the in-chamber temperature at -75°C.
Performance and Reliability: Naturally occurring hydrocarbon refrigerants are environmentally friendly with no ozone depletion. These refrigerants provide more efficiency without compromising cooling performance, ambient tolerance, and recovery speeds following door openings.
Security Control and Monitoring: An eye level, door mounted, 10.1inch high resolution LCD touchscreen allows full user control. A USB port makes transferring logged data easy. Many attributes are displayed in an internal time-temperature log that can be expressed in graphic form over time. It seamlessly integrates with LabSVIFT® for temperature monitoring, predictive analytics, and lab management.
Valuable Sample Storage: TwinGuard series freezers are ideal for safe, long term storage of your most high valued products, such as stem cells, embryos, cell lines, rare specimens, and other biological materials.
Natural Refrigerants: Natural refrigerants with very low Global Warming Potential (GWP), advanced compressors, and integrated electronics help minimize operating costs by reducing energy consumption and heat output.
Electric Lock: Track freezer access with details on who entered, when, and how long the door remained open with four lock options:
- Electric lock with passcode
- Dedicated key per unit
- Facial recognition (optional)
- Proximity card (optional)
Dual Cooling System: The dual cooling system offers ultimate sample protection. The two independent refrigeration systems provide a reliable and exceptionally stable -86°C ultra low temperature environment. If one system unexpectedly fails, the other can maintain the freezer in the -75°C range until service can be arranged.
Filterless Design: The freezer’s filterless design minimizes routine maintenance by eliminating the need for regular filter cleaning.
EZlatch with Electronic Access Control: Standard electronic locking with unique key. Optional upgrades: NFC or facial recognition for advanced security.
