SUS304 High Pressure Steam Sterilizer for Medical and Laboratory Use

Here is the precise English translation of the technical specifications for autoclaves (high-pressure steam sterilizers):

Autoclave Overview

Autoclaves (also known as high-pressure steam sterilizers) utilize pressurized saturated steam to sterilize equipment across medical, scientific research, agricultural, and food industries. By increasing pressure to raise water's boiling point above 100°C (standard conditions: 121°C at 0.1MPa), high-temperature steam eliminates all microorganisms—including bacterial spores—within 15-30 minutes, ensuring sterile safety ‌

Classification & Specifications

Categorized by design and capacity:

• ‌Portable‌:18L/24L/30L capacity for rapid sterilization in labs/small clinics ‌
• ‌Vertical‌:30L-200L capacity; subtypes include manual-handwheel, flip-lid, and smart models (auto-exhaust/drying); suitable for hospitals/factories ‌
• ‌Horizontal‌:Large-scale industrial units for food processing/batch medical instruments ‌

Core Structure & Working Principle

• ‌Components‌:Sealed chamber, pressure gauge, exhaust valve, safety valve, heating element, control system; some feature steam-collection bottles/self-sealing gaskets ‌
• ‌Principle‌:Steam penetrates materials at ≥121°C, sterilizing via microbial protein denaturation ‌

Control & Operational Features

Modern units feature microprocessor controls with:

• ‌Auto-regulation‌:Preset pressure/temperature/duration parameters (e.g., 121°C for 15-30 mins) with real-time monitoring ‌
• ‌Safety mechanisms‌:Overheat protection (auto shutoff), low-water alarms, electrical leakage protection, and dual safety interlocks ‌
• ‌Sterilization modes‌:Standard exhaust, pulse exhaust, or non-exhaust programs for diverse items ‌

Standard Operating Procedure

1. ‌Preparation‌:Add water to outer chamber; load items symmetrically and tighten lid bolts 
2. ‌Air removal‌:Heat to 33.78kPa pressure, open exhaust valve until pressure drops to zero, then close ‌
3. ‌Sterilization‌:Maintain target pressure (e.g., 0.1MPa) for set duration; deactivate heating manually/automatically ‌
4. ‌Cooling‌:Naturally cool to zero pressure before slow venting and unloading ‌

Critical Precautions

• ‌Loading‌:Avoid overpacking to ensure steam penetration ‌
• ‌Air removal‌:Incomplete air elimination causes suboptimal temperatures and sterilization failure ‌
• ‌Safety‌:Post-sterilization pressure must never be immediately vented (risk of liquid boil-over/vessel rupture); regularly inspect seals/gauges ‌

Key Applications

• ‌Medical‌:Sterilizing instruments/surgical supplies per infection control standards ‌
• ‌Research/Education‌:Lab sterilization of culture media/glassware ‌
• ‌Food Industry‌:Thermal processing of canned/vacuum-packed foods (food-grade models required) ‌
• ‌Agriculture/Pharmaceuticals‌:Seed disinfection or drug manufacturing sterilization ‌
