Autoclaves function through moist heat sterilization which achieves 3–10 times the efficiency of dry heat because steam transfers heat better.
During steam condensation 540 calories of latent heat are released from each gram of steam.
Steam possesses the ability to permeate through porous substances along with the lumens of instruments.
Phase Diagram Analysis:
Optimal microbial destruction occurs when steam at 121°C and 15 psi reaches a composition of 97% vapor and 3% liquid.
When temperatures rise above 121°C and moisture levels drop below the optimal range the effectiveness diminishes (for example, steam at 135°C and 30 psi needs precise humidity control).
Autoclave performance hinges on three interdependent variables:
| 매개변수 | Standard Range | Microbial Impact |
|---|---|---|
| 온도 | 121°C – 135°C | Denatures proteins/DNA at 121°C |
| 압력 | 15 – 30 psi | Elevates steam boiling point |
| 시간 | 15 – 60 minutes | Ensures heat penetration |
Formula: [ t = \frac{D_{121} \times \log{N_0/N}}{F_0} ] Where:
( t ): Exposure time
( D_{121} ) represents the time needed for a 90% microbial reduction at 121°C
( N_0/N ): Represents the reduction of microbial population (example: 10^6 to 10^0)
Steam forces air to move downward which works well for solid instruments.
Vacuum-Assisted technology achieves air removal of 99.9% within two minutes for wrapped or textile loads.
Steam quality must meet EN 285 standards:
Dryness fraction ≥97%
Non-condensable gases <3.5%
Minimum Requirements:
121°C for 30 minutes
134°C for 15 minutes (flash cycles)
Controlled pressure release prevents “wet packs”.
Vacuum drying removes residual moisture (≤0.2% humidity).

Q1: Why 121°C for autoclave sterilization? A: 121°C achieves a 10^-6 SAL (Sterility Assurance Level) for 지오바실러스 스테아로모필루스 in 15 minutes, balancing speed and efficacy.
Q2: How to calculate autoclave cycle time for dense loads? A: Add 1 minute per 1kg of stainless steel instruments (e.g., 20kg load requires 20 extra minutes at 121°C).
Q3: Can autoclaves sterilize powders? A: Yes, using specialized cycles with extended dry time. Max recommended: 100g per cycle.
Q4: What’s the lifespan of a hospital-grade autoclave? A: 8–12 years with proper maintenance. Key factors: chamber corrosion resistance and valve quality.
Q5: How to verify steam quality? A: Use a steam quality test kit measuring dryness fraction and non-condensable gases.
