Maintenance for ULT Freezers
Protect your research investment with professional maintenance strategies.
Why Maintenance Matters?
Ultra-Low Temperature (ULT) freezers are the silent guardians of your most valuable samples. When replacements are difficult or prohibitively expensive, proper maintenance is not just a suggestion—it's an essential practice to extend equipment lifespan and ensure 100% sample security.
Professional Installation
- 📍 Level Surface: Must be installed on a flat, vibration-free surface.
- 🌬️ Airflow Space: Maintain at least 5" (back) and 8" (top) clearance.
- ⚡ Dedicated Power: Always use a dedicated circuit to prevent voltage fluctuations.
- 🌡️ Ambient Temp: Keep room temperature between 15°C and 32°C for peak efficiency.

Daily Operational Best Practices
Minimize Exposure
Limit door openings to maintain temperature stability and reduce energy spikes.
Smart Access
Open one inner door at a time. Retrieve samples quickly and close the door immediately.
Sample Pre-cooling
Pre-cool warm samples before loading to prevent system overload.
Optimize Your Storage Space
Efficient organization reduces door-open time. Choose the right rack for your freezer:

Maintenance Checklist
✅ Clean the Filter: Ensure proper airflow by vacuuming the filter monthly. Wash with mild soap if necessary.
✅ Seal Inspection: Check door gaskets for frost buildup or leaks. A tight seal is critical for -86°C performance.
✅ Annual Defrost: Perform a full manual defrost once a year. Plan sample transfers in advance to a backup unit.
Operational Hints
- Keep it Full: A full freezer (using water jugs if necessary) acts as a thermal mass, maintaining temperature better during openings.
- Disaster Planning: Always have a backup power source and a remote monitoring system (like Wi-Fi thermometers) installed.
