| Feature | Single-tier Dry Heat (This Model) | Steam Autoclave |
| Moisture | None | High (condensation) |
| Rust risk | None | High |
| Plumbing required | No | Yes |
| Cycle time | 30-60 min | 15-30 min |
| Suitable for powders/oils | Yes | No |

A: A complete cycle takes 45 to 75 minutes depending on load size and target temperature.
| Temperature | Sterilization Time | Cooling Time | Total Cycle Time |
| 160°C | 40 minutes | 20-25 minutes | 60-65 minutes |
| 170°C | 35 minutes | 15-20 minutes | 50-55 minutes |
| 180°C | 30 minutes | 15-25 minutes | 45-55 minutes |
At 180°C, sterilization time is typically 30 minutes, plus 15–25 minutes for the chamber to cool down to a safe opening temperature (below 80°C). For lightly loaded cycles, the total time may drop to 45 minutes. Always wait until the display shows "cool" before opening the door.
A: No. Standard plastic or rubber materials will melt or deform at 160–180°C. Only items rated for high heat should be placed inside.
Material compatibility guide:
| Material | Suitable for Dry Heat (160-180°C) | Notes |
| Glass (borosilicate) | Yes | Excellent thermal resistance |
| Stainless steel (SUS304, 316) | Yes | Rust-free, durable |
| Carbon steel | Yes | May oxidize over time |
| Aluminum | Yes | Up to 180°C limit |
| Silicone (high-temp grade) | Yes | Max 200°C, check label |
| Polypropylene (PP) | No | Melts at 130-150°C |
| PE (Polyethylene) | No | Melts at 100-120°C |
| Rubber/natural latex | No | Deforms above 100°C |
| PTFE (Teflon) | Yes | Withstands up to 260°C |
The Single-tier High-temperature Sterilizer includes a temperature guide sticker on the door for quick reference. For plastic items, consider low-temperature sterilization methods instead.
A: Clean the interior chamber once every 30 cycles or at least once monthly.
Maintenance schedule:
| Interval | Action |
| After each cycle | Leave door open for 2-3 minutes to cool and ventilate |
| Monthly (or every 30 cycles) | Remove shelf, wipe chamber walls with soft dry cloth |
| Every 2 months | Check door seal for cracks or residue |
| Every 3 months | Vacuum fan intake grille on the back |
| Annually | Professional inspection of heating elements and wiring |
Important:
- Never use water or liquid cleaners inside the chamber – moisture can damage heating elements.
- No routine calibration is needed if the unit displays accurate temperature within ±2°C.
- If temperature drift exceeds ±3°C, contact customer support for calibration service.
