Sterilization time depends on following key variables: Volume - The greater the volume of liquid, the longer it takes for the product to reach temperature. 10x 200ml heats faster than 1x 2L.; Viscosity - Thicker, more viscous solutions absorb heat more slowly than products such as water.; Material of the container - Different containers with the same volume of liquid will reach .

However, can a sterile filter(ex; 0.2 um) be used instead if the autoclave isn't available?The autoclave operator can calculate a lower cycle time for sterilizing the liquid based on the Fo (F Zero) empirical tables. If a normal sterilization holding time is set to 15 minutes, it may be reduced by seconds/minutes based on the Fo calculation. This will help prevent overcooking the liquid while still ensuring proper sterilization.
Why do you want to microwave it instead of autoclaving? It takes < 1 hour to make up and autoclave a supply of LB that will last 3-6 months. Most of that time is hands-off, just waiting for the autoclave cycle to complete. I actually think it would be significantly more annoying to rely on microwaving LB, since you'd have to boil it batch by batch.Made LB broth per label. 2x 500ml h20, 12.5g mix.
