Frequently Asked Questions
How is -40°C storage different from -20°C or -70°C ultra-low freezers?
-40°C is the sweet spot for most biobanking and vaccine storage: cold enough to dramatically slow degradation (half-life extended by ~10–15 years vs. -20°C) yet more energy-efficient than -70°C ultra-low freezers. -70°C is reserved for multi-decade archival (50+ years). For 5–10 year storage, -40°C is ideal.
Will power loss compromise my samples?
The 12+ hour holdover time gives you a buffer. In a typical lab with emergency generator backup, you have ample time to restore power. For critical samples, some institutions add redundant freezers or integrate with facility-wide power management systems.
Can I store vaccines in this freezer?
Yes. Indeecon freezers meet WHO specifications for vaccine cold-chain storage. Most vaccines are stored at 2–8°C or -20°C, but some experimental and next-generation vaccines require -40°C. Consult your vaccine manufacturer's stability data to confirm compatibility.
How often should I defrost?
Modern frost-free designs defrost automatically every 12 hours for 20 minutes during low-demand periods. Manual defrost is also available. Moisture drains to the floor or a collection pan—ensure adequate drainage in your facility.
What temperature monitoring and documentation does this support?
Indeecon offers USB data loggers (100+ readings) or Ethernet-connected versions for continuous remote monitoring. NABL-traceable calibration of internal temperature sensors ensures audit compliance. Export data to Excel or integrate with your LIMS for GxP traceability.
