Applications
- Glassware sterilization & depyrogenation: Dry heat is preferred for borosilicate glassware — no residual moisture, no etching, and effective endotoxin removal at 210°C with ±3.5°C distribution accuracy
- Metal instruments & heat-stable supplies: Forceps, scalpels, spatulas, and probes that cannot tolerate moisture; forced convection eliminates cold spots for consistent sterility assurance
- Powders, oils & moisture-sensitive materials: Talc, starch, petroleum jelly, and mineral oils that cannot be steam sterilized; precise PID control and calibration offset for exact processing conditions
- Pharmaceutical QC & life science: Routine sterilization of consumables and equipment with programmable auto start/stop for unattended overnight cycles
- Food safety & environmental testing: High-capacity 300L chamber reduces sterilization runs per shift for high-throughput lab workflows
- Research & industrial labs: 99-step programmable cycles with memory storage for validated, repeatable protocols
