한국어Ruina Optoelectronic is a trusted supplier of the Double-tier Pull-out Disinfection Cabinet – the professional choice for dental clinics, tattoo studios, veterinary surgeries, and salons seeking organized, chemical-free sterilization.

- Digital Temperature Control – Precise adjustment from 50°C to 180°C for different tool materials.
- Tempered Glass Door – Monitor the cycle without opening and losing heat.
- Overheat Protection – Auto shut-off ensures safety and prevents tool damage.
- Removable Stainless Trays – Each tier pulls out for easy loading, unloading, and cleaning.
- Space-Saving Design – Vertical stacking of two tiers doubles capacity without increasing footprint.
| Feature | Single-Tier Cabinet | Double-tier Pull-out Disinfection Cabinet |
| Storage capacity | Limited to one layer | Two tiers – double the tool capacity |
| Tool organization | Mixed tools on one tray | Separate tiers for sterile vs. clean tools |
| Access ease | Only one opening | Pull-out access to each tier independently |
| Workflow efficiency | One cycle, one load | Two loads in one cycle – save time |
| Footprint | Compact | Same footprint, double capacity |

A: Yes. Unlike steam autoclaves that introduce moisture, the Double-tier Pull-out Disinfection Cabinet uses dry heat or UV-ozone technology with zero humidity. This prevents oxidation, corrosion, and edge blunting.
For carbon steel or hinged tools, set the temperature to 140°C for 30 minutes – this ensures sterility while preserving sharpness and finish.
Recommended settings by tool type:
| Tool Type | Temperature | Time |
| Carbon steel scissors | 140°C | 30 min |
| Stainless steel forceps | 160°C | 45 min |
| Titanium tattoo grips | 120°C | 20 min |
| Tungsten carbide tips | 150°C | 30 min |
A: The Double-tier Pull-out Disinfection Cabinet transforms daily sterilization workflow. The two tiers allow you to:
- Separate instrument categories – Place delicate tools (e.g., scissors, mirrors) on the top tier and heavier tools (e.g., forceps, clamps) on the bottom tier.
- Load one tier while the other is in use – Prepare tools for the next cycle without waiting.
- Easily access tools without bending or reaching – Each tier slides out smoothly to the edge of the cabinet.
- Reduce cross-contamination risk – Keep sterile instruments on the upper tier and dirty tools on the lower tier during loading.
This design is especially valuable in high-volume clinics where time and organization directly impact patient throughput.
A: Only if the cabinet has a low-temperature mode (50-80°C). Standard dry-heat models operate above 140°C, which can melt plastics or damage rubber grips.
For mixed-material tools, select a UV-C + ozone variant operating at room temperature. The Double-tier Pull-out Disinfection Cabinet in UV-C configuration provides gentle, heat-free sterilization suitable for heat-sensitive instruments.
Material compatibility guide:
| Tool Material | Dry Heat (140°C+) | Low-Temp Dry Heat (50-80°C) | UV Cabinet |
| Full metal tools | Yes | Yes | Yes (with limitations) |
| Plastic-handled tools | No | Yes | Yes |
| Rubber-grip tools | No | Yes | Yes |
| Heat-sensitive alloys | No | Yes | Yes |
Always check the tool manufacturer's heat tolerance before sterilization.
| User Type | Primary Application |
| Dental clinics | Mirrors, explorers, orthodontic pliers, forceps |
| Tattoo and piercing studios | Grips, needle holders, forceps |
| Veterinary clinics | Nail trimmers, examination tools, surgical scissors |
| Beauty and nail salons | Cuticle nippers, razors, callus removers |
| Podiatry clinics | Scalpels, probes, debridement tools |
| Surgical centers | Small instrument kits, biopsy forceps |
1. Place on a level, heat-resistant surface – away from flammable materials.
2. Allow 15 cm clearance on all sides for proper ventilation.
3. Always clean tools before loading – remove visible debris, blood, or tissue.
4. Do not overload individual tiers – leave space between tools for hot air circulation.
5. Check slide rails monthly – wipe them with a dry cloth to ensure smooth pull-out action.
| Interval | Action |
| After each cycle | Leave door open for 2 minutes to cool and ventilate |
| Weekly | Wipe interior and pull-out trays with 70% isopropyl alcohol |
| Every 30 cycles | Remove both trays, check for debris under heating elements |
| Monthly | Lubricate slide rails with food-grade silicone spray |
| Every two weeks (high-volume clinics) | Deep clean to maintain airflow and temperature accuracy |
