Understanding OD

Optical Density (OD) measures bacterial concentration by light absorption. OD₆₀₀ is standard for bacteria. During exponential phase, OD doubles at regular intervals.

FAQ

Q: What is a typical doubling time?
A: E. coli: 20-30 min in optimal conditions

Q: What OD range is best?
A: 0.1-0.8 for accurate exponential phase measurements
