A: No, they serve different purposes. An autoclave uses pressurized steam for complete sterilization of invasive surgical tools and is required by medical regulations for implants or cutting through tissue.
RUINA's Sterilization Cabinets for Various Metal Tools are designed for non-critical and semi-critical instruments (e.g., scissors, tweezers, razors, nail tools) that contact intact skin or mucous membranes. They provide high-level disinfection without heat or moisture, ideal for clinics, tattoo shops, and beauty salons where autoclave damage (rust, dulling) is a concern.
Best practice by instrument type:
| Tool Type | Recommended Method |
| Surgical scalpels, implants | Autoclave required |
| Scissors, forceps, nail tools | RUINA UV-Ozone cabinet |
| Tattoo grips, dental mirrors | RUINA UV-Ozone cabinet |
| Heat-sensitive plastic tools | RUINA UV-Ozone cabinet |
A: Tools remain sterile only if stored properly. After a full 20-minute cycle in Sterilization Cabinets for Various Metal Tools, instruments should be used immediately or placed in a sealed, sterile pouch.
Sterility timeline by storage method:
| Storage Condition | Sterility Duration |
| Sealed sterile pouch | Up to 6 months |
| Inside cabinet (door closed, not running) | 4-6 hours |
| Open air on clean tray | 2-4 hours |
| Open air on dirty tray | < 1 hour |
For best practice, run the cabinet just before a procedure and leave tools inside with the door closed until the moment of use – the ozone and UV-C stop automatically when opened, but the inner chamber remains clean.
A: No, it extends their life. Unlike steam autoclaves (which can corrode hinges and loosen carbide tips over time) or chemical soaks (which stain and degrade metal alloys), RUINA's dry UV-ozone process causes zero oxidation or material stress.
In fact, many professional piercers and dental hygienists report that switching to Sterilization Cabinets for Various Metal Tools reduces replacement frequency of precision tools by up to 60%.
The only caution: Carbon steel without protective coating – while rust won't occur inside the cabinet, pre-existing surface imperfections may become visible after cleaning. Always dry tools thoroughly before loading.
