Medical sterilizer BKM series

for sterilization servicessteamsaturated steam

Introduction
The pulse-vacuum Class B tabletop autoclave performs repeated vacuum pulses and steam injections to remove air and allow saturated steam to reach the set pressure and temperature, delivering validated steam sterilization for medical instruments, dressings and liquids.

Key features

• 5-inch LCD touchscreen with real-time display of temperature, pressure, time, program status, alarms and process curve for monitoring and documentation.
• Multiple safety protections: automatic over-temperature protection, door safety interlock, dual over-pressure protection and evaporator control.
• Door options: manual door for K-series (BKM-K18B/BKM-K23B) and automatic door for Z-series (BKM-Z18B/BKM-Z23B) for ergonomic operation.
• Vacuum system: high-efficiency vacuum pump, low noise, ultimate vacuum > -80 kPa for effective air removal and improved drying.
• Program selection: fast, packaged, rubber, dressing, liquid, customizable liquid/solid cycles, enhancement program, B&D test, vacuum test and scheduling.
• Air filtration: 0.22 μm sterilizing filter with ≥99.5% efficiency to prevent recontamination during vacuum break.
• Data recording: integrated thermal printer and USB interface for real-time process records.
• Automated cycle stages: preheating, displacement, heating, sterilization, steam exhaust and vacuum drying; built-in dual water tanks (clean + waste).
